Description

Technical Field

[0001] This invention relates to the field of silicon component processing technology, and in particular, to a graphite groove cutting fixture. Background Technology

[0002] Grooving is an important production process in silicon boat manufacturing. It is mainly used to support silicon wafers, and grooves with the same spacing are cut into the groove bar to support the silicon wafers.

[0003] Conventional processing method: The groove bar is bonded to the fixture with wax. After measuring the position, the first groove is machined. After machining, it is sent for inspection. Once it meets the dimensional requirements, the other grooves can be machined. Generally, there are many grooves on the groove bar. Machining a single groove bar takes about 20 hours, and cutting grooves on multiple groove bars requires a lot of time.

[0004] Currently, in order to improve the grooving efficiency of the grooving rod, the grooving rod is fixed on the grooving fixture. The existing grooving fixture can refer to the grooving fixture in the utility model patent with authorization announcement number CN211941535U. This fixture is made of graphite material and uses two clips on the base to divide the upper part into a slot for placing three grooving rods at the same time. The clips are integrally formed with the base, and the width of the slot between the two clips cannot be adjusted, nor can the tilt angle of the side of the clips be adjusted.

[0005] Since different models of groove bars have different widths, the inclination angle of the applicable clamping strip also varies during the groove cutting process. Different models of groove bars need to be fixed with jigs of corresponding sizes, making it impossible to use one jig to process multiple models of groove bars.

[0006] Therefore, how to design a graphite grooving fixture that can adapt to the processing of various types of grooving bars has become a technical problem that urgently needs to be solved by people in this field. Summary of the Invention

[0007] In order to solve at least one of the technical problems mentioned in the background art, the present invention aims to provide a graphite groove cutting fixture that solves the problem that the fixture cannot be applied to the processing of different types of grooved bars.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A graphite grooving fixture includes a base, a recessed mounting groove on the top wall of the base, a first retaining strip and a second retaining strip slidably connected along the Y-axis within the mounting groove, a width adjustment mechanism on the base for adjusting the gap between the first and second retaining strips, a downwardly extending support plate rotatably connected to the side walls of the first and second retaining strips extending out of the mounting groove, a sliding groove on the bottom wall of the base along the Y-axis, a slider slidably connected within the sliding groove, a connector extending to the sliding groove on the support plate, a slotted hole on the slider along the Z-axis, a pin fixed to the connector and inserted into the slotted hole, an adjustment plate fixed to the slider on the base, a positioning mechanism between the adjustment plate and the base, and a grooving rod clamping assembly for fixing the grooving rod on the adjustment plate.

[0010] Furthermore, the positioning mechanism includes a second positioning groove, a second bolt, and a positioning hole. The positioning hole is located on the top wall of the base. The second positioning groove is arranged along the Y-axis and is located on the adjustment plate. The second positioning groove passes through the adjustment plate vertically. The side wall of the second positioning groove is provided with a positioning step. When the adjustment plate is fixed, the second bolt is threadedly connected to the positioning hole, and the end of the second bolt abuts against the top wall of the positioning step.

[0011] Furthermore, the positioning mechanism also includes an anti-slip pad, which is placed on the positioning step. When the adjusting plate is fixed, the end of the second bolt squeezes the anti-slip pad and causes elastic deformation.

[0012] Furthermore, the grooved bar clamping assembly includes an adjusting groove, a push plate, a push rod, a push block, and an adjusting screw. The adjusting groove is disposed on the top wall of the adjusting plate along the X-axis direction. The side wall of the push plate is slidably connected to the side wall of the adjusting groove along the Y-axis direction. The adjusting screw is rotatably mounted on the adjusting plate and threadedly connected to the push plate. The push rod is fixedly mounted on the push plate and extends through the adjusting groove toward the support plate side. The push block is fixedly mounted on the push rod.

[0013] Furthermore, the push block is provided with a push slope, and the push slope is in the same direction as the inclination of the support plate on the same side.

[0014] Furthermore, the width adjustment mechanism includes a first screw and a second screw fixed to the first screw. The first screw and the second screw are arranged along the Y-axis direction. The first screw is provided with a first threaded section, and the second screw is provided with a second threaded section. The first threaded section is a forward thread, and the second threaded section is a reverse thread. The first threaded section is threadedly connected to the first locking bar, and the second threaded section is threadedly connected to the second locking bar.

[0015] Furthermore, both the first and second clips are equipped with mounting seats, and the mounting seats are provided with internal threads. The first threaded section and the second threaded section are threadedly connected to the internal threads on the corresponding mounting seats.

[0016] Furthermore, the first screw is provided with a first insertion channel, and the second screw is provided with a second insertion channel that extends through both ends. The inner walls of both the first and second insertion channels are provided with first insertion grooves arranged along the Y-axis. The screw also includes a synchronizing rod, a headless bolt, and a third bolt. The outer wall of the synchronizing rod is fixedly provided with a synchronizing insertion rib that inserts into the first insertion groove. When the first screw and the second screw are assembled, the synchronizing insertion rib of the synchronizing rod is simultaneously inserted into the first insertion groove in both the first and second insertion channels. The external thread of the headless bolt is threadedly connected to the internal thread of the second insertion channel. The headless bolt abuts against the synchronizing rod. The third bolt passes through the first screw and is threadedly connected to the synchronizing rod.

[0017] Furthermore, the system includes a torsion nut fixed to the end of the first screw, a insertion hole on the torsion nut, a limit rod rotatably connected in the insertion hole, a limit ring groove on the side wall of the base, a limit block fixedly attached to the end of the limit rod and inserted into the limit ring groove, the longitudinal section of the limit ring groove being transversely T-shaped, the side wall of the limit block abutting against the side wall of the limit ring groove to restrict the movement of the first screw along the Y-axis, and a limit mechanism for restricting the rotation of the limit rod.

[0018] Furthermore, the limiting mechanism includes a positioning sleeve, a limiting slot arranged along the Y-axis on the side wall of the limiting rod, a second insertion groove arranged along the Y-axis on the side wall of the torsion nut, a limiting rib for insertion into the limiting slot inside the positioning sleeve, and an insertion rib inserted into the second insertion groove. When the positioning sleeve and the torsion nut are assembled, the insertion rib is inserted into the second insertion groove, the limiting rib is inserted into the limiting slot, and the positioning sleeve and the torsion nut are fixed by a third bolt.

[0019] Compared with the prior art, the beneficial effects of the present invention are: the present invention adjusts the gap between the first and second card bars through the width adjustment mechanism, thereby enabling the clamping of different types of groove bars, and at the same time fixing the groove bars in the card slot;

[0020] By moving the position of the adjustment plate, the slider can be moved, thereby changing the tilt angle of the support plate and making it suitable for placing different types of groove bars.

[0021] Then, the positioning mechanism is used to fix the adjusting plate on the base to prevent the angle of the support plate from changing during the processing of the groove bar;

[0022] After the groove bar is placed, the groove bar clamping assembly is used to push the groove bar onto the support plate. Compared with the traditional wax-coating method, this simplifies the method of fixing the groove bar and improves the processing efficiency of the groove bar. Attached Figure Description

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] This embodiment provides a graphite grooving fixture, which is mainly used for grooving processing of different types of grooving bars.

[0042] like Figure 1 As shown, it includes a base 1. In this embodiment, its orientation is first redefined. The direction along the length of the base 1 is defined as the X-axis direction, the direction along the width of the base 1 is defined as the Y-axis direction, and the direction along the height of the base 1 is defined as the Z-axis direction.

[0043] like Figure 2As shown, the top wall of the base 1 is provided with a downwardly recessed mounting groove 13, in which a locking strip 2 that slides along the Y-axis is installed. Specifically, there are two locking strips 2, including a first locking strip 21 and a second locking strip 22. The first locking strip 21 and the second locking strip 22 are arranged along the X-axis, and a slot is formed between the first locking strip 21 and the second locking strip 22 for placing one of the grooved bars. The base 1 is also provided with a width adjustment mechanism 6 for adjusting the position of the first locking strip 21 and the second locking strip 22. The width adjustment mechanism 6 can adjust the first locking strip 21 and the second locking strip 22 synchronously, thereby adjusting the width of the slot to accommodate the clamping of different types of grooved bars.

[0044] It is worth noting here that different models of groove bars may have different widths.

[0045] In order to adjust the positions of the first card strip 21 and the second card strip 22, in this embodiment, as follows: Figure 5 and Figure 7 As shown, the width adjustment mechanism 6 includes a first screw 61 and a second screw 62 fixedly connected to the first screw 61. The outer wall of the first screw 61 is provided with a first threaded section 601, and the second screw 62 is provided with a second threaded section 602. Specifically, the first threaded section 601 is configured to rotate clockwise, and the second threaded section 602 is configured to rotate counterclockwise. The first threaded section 601 is threadedly connected to the first locking strip 21, and the second threaded section 602 is threadedly connected to the second locking strip 22.

[0046] With the above settings, when the fixture clamps different types of grooved bars, by rotating the first screw 61, the second screw 62 can be driven to rotate synchronously. Since the first threaded section 601 and the second threaded section 602 have opposite rotation directions, the first clamping bar 21 and the second clamping bar 22 can be driven to move synchronously in opposite directions, thereby enabling the clamping of different types of grooved bars.

[0047] To improve the stability of the movement of the first locking bar 21 and the second locking bar 22 along the Y-axis, in this embodiment, as follows: Figure 6 As shown, the side wall of the mounting groove 13 is provided with a first sliding groove 131 arranged along the Y-axis direction. The side walls of the first locking strip 21 and the second locking strip 22 are each provided with a guide rib 23 that is inserted into the first sliding groove 131. The guide rib 23 is slidably connected to the first sliding groove 131, thereby maintaining the stability of the first locking strip 21 and the second locking strip 22 during movement.

[0048] In this embodiment, as Figure 6 and Figure 8 As shown, the portion extending to the upper side of the top wall of the base 1 is mainly rectangular. When the first locking bar 21 and the second locking bar 22 move relative to each other, in order to support the groove bar 200 between the two locking bars 2, as shown... Figure 6As shown, the first clip 21 and the second clip 22 are each fixedly provided with a plurality of support plates 25 on their sidewalls close to each other. The first clip 21 has a plurality of first insertion holes 211 through which the support plates 25 on the second clip 22 pass, and the second clip 22 has a plurality of second insertion holes 221 through which the support plates 25 on the first clip 21 pass. During the installation of the first clip 21 and the second clip 22, the support plates 25 are inserted into the corresponding first insertion holes 211 or second insertion holes 221. At this time, the sidewall of the support plate 25 is slidably connected to the inner wall of the first insertion hole 211 or the inner wall of the second insertion hole 221. It is worth noting that the top wall of the support plate 25 is flush with the top wall of the base 1, and the support plate 25 is used to support the groove bar 200 between the first clip 21 and the second clip 22.

[0049] At the same time, the support plate 25 is inserted into the first insertion hole 211 and the second insertion hole 221, which can further enhance the stability of the relative movement process of the first locking strip 21 and the second locking strip 22.

[0050] In order to support the grooved bars 200 on both sides of the card strip 2, in this embodiment, as follows: Figure 2 , Figure 3 and Figure 14 As shown, the first clip 21 and the second clip 22 extend from the side wall of the mounting groove 13 and are rotatably mounted with support plates 3. The support plates 3 are provided with two plug rods 32 that are rotatably connected to the side wall of the clip 2. Specifically, the two plug rods 32 on the support plates 3 are distributed along the X-axis direction. The bottom end of the support plates 3 is slidably connected to the top wall of the base 1. The base 1 is also provided with an angle adjustment mechanism to adjust the tilt angle of the support plates 3.

[0051] To prevent interference between the support plate 3 and the locking strip 2 on the same side during the angle adjustment of the support plate 3, in this embodiment, as follows: Figure 14 As shown, the support plate 3 is provided with an avoidance groove 31 to solve the problem of collision between the support plate 3 and the card strip 2.

[0052] In order to achieve the angle adjustment of the support plate 3, in this embodiment, as follows: Figure 3 As shown, the side wall of the base 1 is provided with several sliding grooves 18 arranged along the Y-axis and opening upwards. The longitudinal section of the sliding groove 18 is inverted T-shaped. A slider 4 is provided in the sliding groove 18 and slidably connected along the Y-axis. A connecting plate 41 is provided on the side of the slider 4 near the support plate 3. A connector 33 is fixed on the support plate 3, extending downward into the sliding groove 18 and movably connected to the connecting plate 41. The angle adjustment mechanism also includes a positioning mechanism for fixing the slider 4 on the base 1.

[0053] With the above settings, when it is necessary to adjust the angle of the support plate 3, the positioning mechanism is released from limiting the position of the slider 4. At this time, the clip 2 is stationary in any position. By adjusting the position of the slider 4 in the sliding groove 18, the bottom of the support plate 3 can be rotated around the plug rod 32 through the connecting plate 41 and the connecting head 33. This allows the angle between the support plate 3 and the upper wall of the base 1 to be adjusted, thereby realizing the angle adjustment of the support plate 3 to accommodate the fixing of different types of groove rods 200.

[0054] To enable the movable installation of connector 33 and connecting plate 41, and to accommodate the vertical movement of connector 33 after the angle of support plate 3 changes, in this embodiment, as follows: Figure 3 As shown, the connecting plate 41 is provided with a waist hole 411 arranged along the Z-axis direction, and the connector 33 is fixedly provided with a pin 331 inserted into the waist hole 411, wherein the outer wall of the pin 331 abuts against the side wall of the waist hole 411.

[0055] With the above settings, since the position of the clip 2 remains unchanged, the angle of the support plate 3 changes, which causes the connector 33 to swing around the axis of the plug rod 32. At this time, the position of the pin 331 in the Z-axis and Y-axis directions changes. The change of the pin 331 in the Y-axis will push the slider 4 to move inside the sliding groove 18. The movement of the pin 331 in the Z-axis direction will be eliminated by the longitudinal gap of the waist hole 411, thus solving the installation problem between the connector 33 and the connecting plate 41.

[0056] Since slider 4 is located inside sliding groove 18, it is inconvenient to manually push slider 4. Therefore, in this embodiment, as Figure 3 As shown, the upper wall of the base 1 is provided with an adjustment plate 5 that is fixedly connected to the slider 4. Specifically, the adjustment plate 5 is provided with a downwardly recessed countersunk hole 51, and the top wall of the slider 4 is provided with a downwardly recessed bolt hole 42. A first bolt 501 is provided in the countersunk hole 51. The first bolt 501 is threadedly connected to the inner wall of the bolt hole 42. The end of the first bolt 501 sinks into the countersunk hole 51, thereby completing the fixation of the slider 4 and the adjustment plate 5.

[0057] After the angle of the support plate 3 is adjusted, in order to fix the adjusting plate 5 on the base 1, in this embodiment, as follows: Figure 4 and Figure 14As shown, the top wall of the base 1 is provided with a positioning hole 19, and the top wall of the adjusting plate 5 is provided with a second positioning groove 52 that runs vertically through the base. The side wall of the second positioning groove 52 is provided with a positioning step 521. The second positioning groove 52 is set along the Y-axis direction to accommodate the movement of the slider 4 in the Y-axis direction. A second bolt 523 is also provided in the second positioning groove 52. After the angle of the support plate 3 is adjusted, the outer wall of the second bolt 523 is threadedly connected to the inner wall of the positioning hole 19, so that the end of the second bolt 523 abuts against the positioning step 521. The friction between the end of the second bolt 523 and the end face of the positioning step 521 restricts the adjustment plate 5 from moving further.

[0058] To increase the friction between the end of the second bolt 523 and the positioning step 521, in this embodiment, as follows: Figure 4 and Figure 14 As shown, an anti-slip pad 522 is placed on the positioning step 521. When the adjusting plate 5 is fixed, the end of the second bolt 523 abuts against the anti-slip pad 522, squeezing the anti-slip pad 522 to deform it, further increasing the friction between the two and increasing the stability of the adjusting plate 5.

[0059] In conventional machining processes, groove bars 200 are fixed to fixtures using wax adhesion. However, this method is cumbersome, requiring the wax to be melted. Therefore, in this embodiment, as... Figure 14 and Figure 16 As shown, the top wall of the adjusting plate 5 is provided with a downwardly recessed adjusting groove 53, wherein the adjusting groove 53 is arranged along the X-axis direction, and the inner wall of the adjusting groove 53 is provided with a push plate 54 slidably connected along the Y-axis direction. An adjusting screw 55 is rotatably installed on the adjusting plate 5 and threadedly connected to the push plate 54. A push rod 541 extending out of the adjusting plate 5 through the adjusting groove 53 is fixedly provided on the side wall of the push plate 54 near the support plate 3, wherein a push block 56 is fixedly installed at the end of the push rod 541.

[0060] After the angle of the support plate 3 is adjusted, place the groove bar 200 on the outside of the clip 2 and attach it to the side wall of the support plate 3. Rotate the adjusting screw 55, which will drive the push plate 54 to move, and then drive the push block 56 to move through the push rod 541, thereby clamping the groove bar 200 between the push block 56 and the support plate 3, thus fixing the groove bars 200 on both sides of the clip 2.

[0061] To improve the stability of the groove bars 200 on both sides of the card strip 2, in this embodiment, as follows: Figure 16As shown, the longitudinal section of the push block 56 is a right trapezoid, and the push inclined surface 561 on the push block 56 is in the same direction as the inclination of the support plate 3. When the push block 56 presses the groove bar 200, it will apply a downward force to the groove bar 200, pushing the groove bar 200 onto the inclined surface of the support plate 3, preventing the groove bar 200 from moving upward along the inclined surface of the support plate 3 during the fixing process.

[0062] In this embodiment, the base 1, the support plate 3, and the clip 2 are made of graphite.

[0063] Since the base 1 is made of graphite, the installation method of the first retaining strip 21 and the second retaining strip 22 on both sides is restricted. During the processing, it is necessary to avoid the metal material from affecting the groove bar and the tool from colliding with the fixed parts. The fixed parts need to be hidden inside the base 1.

[0064] Therefore, in this embodiment, as Figure 5 , Figure 6 and Figure 7 As shown, the base 1 includes a first base body 11 on the left and a second base body 12 on the right, wherein the first base body 11 and the second base body 12 are fixedly assembled into the base 1 body by positioning screws 15.

[0065] Since the first screw 61 and the second screw 62 are threadedly connected to the first clamping strip 21 and the second clamping strip 22 respectively, and the first clamping strip 21 and the second clamping strip 22 are made of graphite, the movement of the first clamping strip 21 and the second clamping strip 22 needs to be achieved through the engagement of the threads, which can easily cause wear on the graphite material and reduce the service life of the fixture.

[0066] In this embodiment, as Figure 5 , Figure 7 and Figure 9 As shown, the first clip 21 and the second clip 22 located in the mounting groove 13 are provided with through holes 24, wherein a mounting base 7 is fixedly installed inside the through hole 24. The mounting base 7 is cylindrical, and the inner wall of the mounting base 7 is provided with an internal thread 701 that is adapted to the first threaded section 601 and the second threaded section 602. The first threaded section 601 and the second threaded section 602 are both threadedly connected to the internal thread 701.

[0067] Specifically, the mounting base 7 includes a mounting cylinder 71, with an internal thread 701 on the inner wall of the mounting cylinder 71. One end of the mounting cylinder 71 is fixedly provided with a first retaining ring 711 extending radially outward along the mounting cylinder 71, such as... Figure 9As shown, the through hole 24 is provided with a number of limiting holes 26 in the circumference. Specifically, there are three limiting holes 26 and they are evenly distributed along the circumference of the through hole 24. A limiting rod 712 that can be inserted into the limiting hole 26 is fixed on the first retaining ring 711. It also includes a second retaining ring 72 and a fourth bolt 73 that fixes the second retaining ring 72 to the other end of the mounting cylinder 71.

[0068] During the installation of the mounting base 7, the mounting cylinder 71 is first passed through the through hole 24, so that the limiting rod 712 on the first retaining ring 711 is aligned with the limiting hole 26. Then, the limiting rod 712 is inserted into the limiting hole 26, thereby limiting the rotation of the mounting cylinder 71. Then, the second retaining ring 72 is fixed to the mounting cylinder 71 on the side away from the first retaining ring 711 by the fourth bolt 73. The second retaining ring 72 is used to limit the movement of the entire mounting base 7 along the Y-axis, thereby realizing the installation of the mounting base 7.

[0069] To facilitate the installation of the first retaining strip 21, the second retaining strip 22, the first screw 61, and the second screw 62, in this embodiment, the installation steps of the retaining strip 2 are as follows:

[0070] The first step is to insert the support plate 25 on the first card strip 21 into the second insertion hole 221 on the second card strip 22, and at the same time insert the support plate 25 on the second card strip 22 into the first insertion hole 211 on the first card strip 21.

[0071] The second step is to move the first seat 11 and the second seat 12 toward the first clip 21 and the second clip 22 from the left and right sides respectively, and then align the guide rib 23 on the clip 2 with the first sliding groove 131 in the mounting groove 13, so that the guide rib 23 is inserted into the mounting groove 13.

[0072] The third step is to use positioning screws 15 to fix the first seat 11 and the second seat 12 together.

[0073] Fourth step, pass the first screw 61 through the mounting hole 16 on the first base 11 and then thread it to the mounting seat 7 on the first clip 21; pass the second screw 62 through the mounting hole 16 on the second base 12 and then thread it to the mounting seat 7 on the second clip 22.

[0074] Fifth step, fix the first screw 61 and the second screw 62, and then restrict the first screw 61 and the second screw 62 from moving along the Y-axis.

[0075] To achieve the fixation of the first screw 61 and the second screw 62, in this embodiment, as follows: Figure 5 and Figure 7As shown, the first screw 61 has a first insertion channel 603 at one end near the second locking strip 22, and the second screw 62 has a second insertion channel 621 extending through both ends. The side walls of the first insertion channel 603 and the second insertion channel 621 are provided with a first insertion groove 622 arranged along the Y-axis direction. It also includes a synchronizing rod 67 for insertion into the first insertion channel 603 and the second insertion channel 621, and a headless bolt 68 for restricting the movement of the synchronizing rod 67 along the Y-axis direction. The peripheral wall of the synchronizing rod 67 is provided with a synchronizing insertion rib 671 that inserts into the first insertion groove 622.

[0076] With the above configuration, when the end of the first screw 61 abuts against the end of the second screw 62, the synchronous insertion rib 671 on the synchronous rod 67 is aligned with the first insertion slot 622, and then inserted into the second screw 62 from the second insertion channel 621 until one end of the synchronous rod 67 is inserted into the first insertion channel 603 in the first screw 61, enabling the first screw 61 and the second screw 62 to rotate synchronously in the circumferential direction. Then, the headless bolt 68 is installed in the second insertion channel 621 of the second screw 62, wherein the external thread of the headless bolt 68 is threadedly engaged with the internal thread in the second insertion channel 621, enabling the headless bolt 68 to be fed. When the end of the headless bolt 68 abuts against the end of the synchronous rod 67, and at the same time the end of the synchronous rod 67 abuts against the end wall of the first insertion channel 603, the movement of the synchronous rod 67 in the Y-axis direction can be restricted.

[0077] To limit the movement of the first screw 61 along the Y-axis, in this embodiment, as follows: Figure 10 , Figure 11 and Figure 12 As shown, a torsion nut 63 is fixedly provided at the end of the first screw 61 extending from the first base 11. The torsion nut 63 is cylindrical and its diameter is larger than that of the first screw 61. The first base 11 is provided with a limiting ring groove 100 located outside the mounting hole 16. The longitudinal section of the limiting ring groove 100 is a transverse T-shape. The torsion nut 63 is provided with a insertion hole 632 and includes a limiting rod 64 passing through the insertion hole 632. The limiting rod 64 is rotatably connected to the insertion hole 632. The end of the limiting rod 64 is provided with a limiting block 641 that can be inserted into the limiting ring groove 100. When the limiting block 641 rotates 90 degrees, the side wall of the limiting block 641 abuts against the side wall of the limiting ring groove 100, preventing the limiting block 641 from moving out of the limiting ring groove 100 again.

[0078] With the above settings, when the first screw 61 is inserted into the limit position through the mounting hole 16, the angle between the limiting rod 64 and the limiting block 641 is adjusted so that the limiting block 641 is inserted into the limiting ring groove 100. Then the limiting rod 64 is rotated ninety degrees to restrict the movement of the limiting block 641 along the Y-axis. Then the circumferential rotation of the limiting rod 64 is used for limiting, thereby restricting the movement of the first screw 61 along the Y-axis.

[0079] In order to limit the circumferential rotation of the limiting rod 64, in this embodiment, as follows: Figure 11 and Figure 12 As shown, the device includes a positioning sleeve 65, a limiting slot 642 arranged along the Y-axis on the side wall of the limiting rod 64, a limiting rib 651 inserted into the limiting slot 642 inside the positioning sleeve 65, a second insertion groove 631 arranged along the Y-axis on the side wall of the torsion nut 63, an insertion rib 652 inserted into the second insertion groove 631 on the inner side wall of the positioning sleeve 65, and a third bolt 66 for fixing the positioning sleeve 65 to the torsion nut 63. The torsion nut 63 is also provided with an indicator mark 633.

[0080] Specifically, through the above settings, such as Figure 13 As shown, when the limiting block 641 is inserted into the limiting ring groove 100, the limiting rod 64 is rotated so that the limiting slot 642 on the limiting rod 64 is aligned with the indicator mark 633. At this time, the limiting block 641 cannot be removed from the limiting ring groove 100, thus restricting the axial movement of the first screw 61. Then, the insertion rib 652 on the positioning sleeve 65 is inserted into the second insertion slot 631 on the torsion nut 63. This restricts the circumferential rotation of the positioning sleeve 65. The limiting rib 651 on the positioning sleeve 65 is inserted into the limiting slot 642, thereby restricting the rotation of the limiting rod 64. In order to restrict the relative movement of the positioning sleeve 65 and the torsion nut 63 along the Y-axis, the positioning sleeve 65 and the torsion nut 63 are fixedly connected by the third bolt 66.

[0081] It is worth noting that in this embodiment, as Figure 5 and Figure 15 As shown, the third bolt 66 is arranged along the Y-axis direction, and the end of the third bolt 66 is threadedly connected to the synchronizing rod 67 to fix the second screw 62 and the first screw 61.

[0082] It is worth noting that in this embodiment, the threaded connection between the third bolt 66 and the synchronizing rod 67 restricts the movement of the synchronizing rod 67 along the Y-axis. The synchronous circumferential rotation of the first screw 61 and the second screw 62 is achieved by using the synchronous insertion rib 671 on the synchronizing rod 67. Compared with the solution of directly connecting the third bolt 66 to the second screw 62 by thread, this method has the following advantages.

[0083] Firstly, the third bolt 66 directly passes through the first screw 61 and is threadedly connected to the second screw 62. At this time, the thread of the third bolt 66 restricts the movement of the second screw 62 along the Y-axis and also ensures that the second screw 62 and the first screw 61 rotate synchronously. During this process, the third bolt 66 and the second screw 62 are prone to stripping during the circumferential rotation of the first screw 61. In this solution, the axial movement of the first screw 61 and the second screw 62 is solved by the third bolt 66, and the problem of synchronous circumferential rotation of the first screw 61 and the second screw 62 is solved by the synchronous insertion rib 671, which improves the stability of the connection between the first screw 61 and the second screw 62.

[0084] To improve the grooving efficiency of the groove bar 200, three groove bars are generally processed simultaneously. One groove bar 200 is placed in the groove between the two clamping strips 2 and clamped by the measuring clamping strip 2 to fix the middle groove bar 200. The other two groove bars 200 are placed on one side of the first clamping strip 21 and the second clamping strip 22 respectively, and then fixed by the push block 56.

[0085] In order to align the ends of the three grooved rods 200, in this embodiment, as follows: Figure 1 and Figure 8 As shown, the top wall of the base 1 is provided with a positioning baffle 14. After the three grooved rods 200 are placed, the ends of the three grooved rods 200 are simultaneously abutted against the positioning baffle 14 to achieve the initial positioning of the grooved rods 200.

[0086] To fix the fixture on the workbench, in this embodiment, several first positioning blocks 8 are provided along the X-axis direction. The first positioning blocks 8 are made of 45# steel. Specifically, eight first positioning blocks 8 are provided, four on each side of the base 1. The top wall of the base 1 has a recessed, waist-shaped first positioning groove 17 that communicates with the side wall. Each first positioning block 8 has a positioning plug 81 that matches the shape of the first positioning groove 17. When installing the first positioning block 8, as... Figure 8 As shown, align the positioning plug 81 with the first positioning groove 17, and then insert the positioning plug 81 into the first positioning groove 17 from top to bottom. An electromagnet is provided on the worktable to attract the bottom wall of the first positioning block 8, thereby fixing the first positioning block 8 on the worktable. (The text then repeats itself, so the translation reflects this.) Figure 8 As shown, the first positioning groove 17 does not penetrate the base 1. At this time, the top wall of the positioning plug 81 abuts against the bottom wall of the first positioning groove 17, thereby restricting the base 1 from moving upward. Since the first positioning groove 17 is waist-shaped, it can restrict the base 1 from moving along the X-axis and Y-axis, thereby achieving the positioning of the base 1.

[0087] Due to the process of base 1, in order to prevent the two ends of base 1 from tilting upwards, in this embodiment, as follows: Figure 8The diagram also includes two L-shaped second positioning blocks 9, which are made of 45 steel. One side of the second positioning block 9 is attached to the worktable, and the other side is pressed against the top wall of the base 1, thereby solving the problem of the base 1 tilting at both ends.

[0088] During the processing of the groove bar 200, in order to improve the stability of the fixture, the groove bar 200 needs to be placed in the middle position of the fixture to prevent the positions of the two clamping strips 2 from deviating from the central axis of the fixture. Therefore, after the clamping strips 2 are installed, they should be symmetrical about the central axis of the fixture.

[0089] To ensure accurate installation of the card strip 2 and prevent it from shifting, the installation method is as follows:

[0090] The installation method is based on the first clip 21 and the second clip 22 being engaged and installed in the mounting groove 13, with the first seat 11 and the second seat 12 being fixed by the positioning screws 15.

[0091] like Figure 15 As shown, in the first step, the first retaining bar 21 is moved to the left so that it abuts against the side wall of the mounting groove 13, and the first retaining bar 21 is moved to the limit position. At this time, the first screw 61 is passed through the mounting hole 16, and then the first threaded section 601 on the first screw 61 is threadedly connected to the internal thread 701 on the mounting base 7. At this time, the first screw 61 is fed into the first base body 11 and moves along the Y axis. When the first screw 61 is installed to the limit position, the rotation of the first screw 61 is stopped.

[0092] The second step is to use the limiting rod 64 to drive the limiting block 641 to be inserted into the limiting ring groove 100, and then twist the limiting rod 64 so that the side wall of the limiting block 641 abuts against the side wall of the limiting ring groove 100, thereby restricting the first screw 61 from moving along the Y-axis.

[0093] Third, move the second locking bar 22 to the right to its limit position and abut against the side wall of the mounting groove 13. At this time, insert the second screw 62 into the mounting hole 16. The second threaded section 602 on the second screw 62 is threadedly connected to the internal thread 701 of the mounting seat 7 on the second locking bar 22. Continue to rotate the second screw 62. At this time, the second screw 62 feeds along the Y axis in the direction of the first screw 61. When the second screw 62 abuts against the first screw 61, stop rotating the second screw 62.

[0094] Fourth step: Align the synchronous insertion rib 671 on the synchronous rod 67 with the first insertion slot 622, and push it toward the first screw 61 so that part of the synchronous rod 67 is inserted into the first insertion channel 603 of the first screw 61.

[0095] Fifth step, connect the external thread of the headless bolt 68 to the internal thread of the second insertion channel 621, so that the end of the headless bolt 68 abuts against the end of the synchronizing rod 67;

[0096] The sixth step is to insert the limiting rib 651 on the positioning sleeve 65 into the limiting slot 642 on the limiting rod 64, and at the same time, insert the insertion rib 652 into the second insertion groove 631 on the side wall of the torsion nut 63 to restrict the circumferential rotation of the limiting rod 64 and prevent the limiting rod 64 from rotating back.

[0097] Step 7: Set the third bolt 66 along the Y-axis to fix the positioning sleeve 65 to the first screw 61. At the same time, the end of the third bolt 66 is threaded to the synchronizing rod 67, so that the first screw 61 and the second screw 62 become one.

[0098] After completing steps 1-7 as described above, the first locking bar 21 and the second locking bar 22 can be moved synchronously by rotating the positioning sleeve 65, and the first locking bar 21 and the second locking bar 22 can always be symmetrical about the central axis of the fixture.

[0099] After the fixture is installed and fixed on the workbench, in order to fix the groove bar 200, firstly, as... Figure 4 As shown, the second bolt 523 is unscrewed upwards to release the pressure between the end of the second bolt 523 and the anti-slip pad 522; second, one of the grooved bars is placed into the groove between the first locking strip 21 and the second locking strip 22, and the end of the grooved bar abuts against the positioning baffle 14; third, by rotating the positioning sleeve 65, the first screw 61 and the second screw 62 are rotated synchronously, thereby adjusting the gap between the first locking strip 21 and the second locking strip 22, thereby clamping and fixing the grooved bar 200; during the movement of the locking strip, the slider 4 is pushed along the Y-axis direction by the connector 33 and the connecting plate 41; fourth, the remaining grooved bar 200 is placed on the support plate 3, and the adjusting plate 5 is manually pushed, thereby driving the slider 4 to move. At this time, the angle of the support plate 3 can be adjusted to accommodate the placement of the grooved bar 200.

[0100] Fifth, by rotating the second bolt 523, the end of the second bolt 523 is brought into contact with the anti-slip pad 522, thereby fixing the position of the adjusting plate 5;

[0101] Sixth, make the grooved bar 200 on the outside of the card strip 2 abut against the positioning baffle 14, so that the multiple grooved bars 200 are aligned;

[0102] Seventh, by rotating the adjusting screw 55, the movement of the push plate 54 and the push block 56 is adjusted, so that the groove bar 200 is clamped between the push inclined surface 561 and the support plate 3, thus completing the fixation of the groove bar 200.

[0103] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
