Description

Technical Field

[0001] This application relates to the technical field of metal product processing, and in particular to a deburring fixture. Background Technology

[0002] Hardware products are auxiliary and accessory manufactured goods used in daily life and industrial production. Originally, they were mostly made of metals such as gold, silver, copper, iron, and tin, hence the name. However, currently, in addition to various metals, non-metallic materials such as plastics and fiberglass are widely used. Hardware products often undergo grooving and other processes, inevitably creating burrs. Therefore, deburring is necessary. In related technologies, if a hardware product has multiple parallel grooves, workers need to use a deburring knife to process each groove to complete the deburring process.

[0003] Regarding the aforementioned technologies, there is a drawback: when using a deburring knife to process each through groove, the worker needs to constantly switch the position of the hardware in their hand to complete the processing of all through grooves, resulting in low deburring efficiency. Summary of the Invention

[0004] To improve the efficiency of deburring, this application provides a deburring fixture.

[0005] The deburring fixture provided in this application adopts the following technical solution:

[0006] A deburring fixture, comprising:

[0007] A placement stand for placing workpieces;

[0008] A positioning component is disposed on the placement seat, the positioning component being used to position the workpiece at a predetermined position on the placement seat;

[0009] The skateboard is slidably connected to the placement seat;

[0010] A cutting tool is connected to the slide plate, and the cutting tool is used to fit the workpiece.

[0011] By adopting the above technical solution, when deburring a workpiece, the workpiece is first placed on the upper surface of the placement seat. Then, the workpiece is adjusted to the predetermined position by the positioning component. Then, by moving the slide plate, the cutting edge on the tool simultaneously deburrs multiple through slots on the workpiece. After the slide plate moves back and forth once, the workpiece is finally removed from the placement seat, thus completing the deburring process. Compared with the manual deburring method of using a deburring tool to deburr each through slot of the workpiece, this design method has the advantages of allowing the tool to process multiple through slots on the workpiece simultaneously, and the workpiece does not need to constantly change its posture during the tool movement, thereby improving the efficiency of deburring.

[0012] Preferably, the movement path of the slide has a processing start point and a processing end point; the positioning component includes a first limiting plate and a second limiting plate, the first limiting plate is fixedly connected to the upper surface of the placement seat, and the first limiting plate is used to abut against one side of the workpiece; the second limiting plate is fixedly connected to the upper surface of the placement seat, and the second limiting plate is used to abut against the other side surface of the workpiece, and the second limiting plate is located at the processing end point.

[0013] By adopting the above technical solution, due to the setting of the first limiting plate and the second limiting plate, on the one hand, during the process of the slide moving from the processing start point to the processing end point, the workpiece will not move away from the second limiting plate. On the other hand, during the process of the slide moving from the processing end point to the processing start point, the friction between the tool and the workpiece will be reduced due to the deburring process. At the same time, there is also a certain friction between the workpiece and the placement seat. Therefore, the workpiece is not easy to move away from the second limiting plate. Thus, by simply making the two adjacent side surfaces of the workpiece abut against the first limiting plate and the second limiting plate respectively, the purpose of stably placing the workpiece on the predetermined position on the upper surface of the placement seat can be achieved.

[0014] Preferably, the upper surface of the placement seat is provided with two uprights spaced apart, and two parallel and spaced mounting guide rods are fixedly connected between the two uprights; the slide plate is slidably sleeved on the two mounting guide rods; the mounting guide rods are slidably sleeved with multiple connecting sleeves, and each connecting sleeve is provided with a ball bearing on its peripheral outer wall, the ball bearing abutting against the slide plate.

[0015] By adopting the above technical solution, on the one hand, the setting of the stand and the installation guide rod realizes the basic sliding connection between the skateboard and the placement seat; on the other hand, due to the setting of the connecting sleeve and the ball bearing, the skateboard will move to different connecting sleeves during the movement of the skateboard, so the resistance encountered by the skateboard during the movement will be less than the sliding friction between the connecting sleeve and the installation guide rod, thus making it easier for the staff to move the skateboard.

[0016] Preferably, a return spring is provided on the portion of the mounting guide rod near the processing endpoint. One end of the return spring is connected to the stand near the processing endpoint, and the other end is connected to one of the connecting sleeves near the processing endpoint.

[0017] By adopting the above technical solution, due to the setting of the return spring, and the fact that there is also a certain rolling friction between the connecting sleeve and the slide plate, the return spring will apply a force to the slide plate in the direction of the processing start point through the connecting sleeve during the process of the slide plate moving from the processing end point to the processing start point, so that the operator can more easily reset and move the slide plate.

[0018] Preferably, the slide plate is connected to a first mounting base and a second mounting base. The first mounting base is fixedly connected to the slide plate. The first mounting base is provided with a first connecting groove, and a first connecting shaft is connected to two opposite side walls of the first connecting groove. One end of the second mounting base is rotatably sleeved on the first connecting shaft, and the other end of the second mounting base is connected to the cutting tool.

[0019] By adopting the above technical solution, since one end of the second mounting seat is rotatably sleeved on the first connecting shaft, during the process of the slide moving from the processing start point to the processing end point, the second mounting seat will be slightly pressed down at the end away from the first connecting shaft due to the friction between the tool and the workpiece, thereby better deburring the workpiece. During the process of the slide moving from the processing end point to the processing start point, the second mounting seat will also be slightly tilted upward at the end away from the first connecting shaft due to the friction between the tool and the workpiece, thereby making it less likely for the tool to scratch the workpiece.

[0020] Preferably, the second mounting base has a second connecting groove at the end away from the first connecting shaft, and a second connecting shaft is connected to the two opposite sidewalls of the second connecting groove; the cutting tool includes:

[0021] A connecting column is rotatably sleeved on the second connecting shaft, and an installation groove is provided on the outer peripheral wall of the connecting column;

[0022] An unlocking spring is provided in the mounting slot;

[0023] A connecting magnet is slidably connected in the mounting groove, the connecting magnet is connected to the unlocking spring, and the sliding direction of the connecting magnet is parallel to the groove opening direction of the mounting groove;

[0024] The blade has one end connected to the connecting magnet and the other end capable of entering and exiting the slot of the mounting groove;

[0025] An abutment block is connected to the connecting magnet, and the abutment block is connected to the end of the connecting magnet away from the first limiting plate;

[0026] A partition ring is connected to the second mounting base. The partition ring is sleeved on the connecting post. The partition ring abuts against the abutting block to restrict the blade from sliding out of the mounting groove. The partition ring is provided with an unlocking notch.

[0027] A rotation limiter is disposed on the second mounting base, and the rotation limiter is used to keep the connecting column in a predetermined posture.

[0028] By adopting the above technical solution, when deburring workpieces of different specifications, first rotate the connecting column until the mounting slot with the corresponding specification blade on the connecting column is rotated to the unlocking notch. Then, the unlocking spring will apply a force to the connecting magnet in the direction of the mounting slot opening, so that the abutment block and the end of the blade away from the connecting magnet will be disengaged from the mounting slot opening. Then, by rotating the limiting member, the connecting column is kept in this position, so that the tool can be switched to the state that is suitable for workpieces of different specifications.

[0029] Preferably, the slide plate includes two connecting parts, a functional part, and a flip-locking member. The two connecting parts are spaced apart and are respectively connected to two mounting guide rods. A mounting shaft is connected at the gap between the two connecting parts. The functional part is connected to the cutter and has an oval-shaped connecting slide hole. The length direction of the connecting slide hole is perpendicular to the upper surface of the placement seat, and the mounting shaft passes through the connecting slide hole. The flip-locking member is connected to both the connecting parts and the functional part. Two cutters are centrally symmetrically arranged on the functional part relative to the mounting shaft.

[0030] By adopting the above technical solution, since the functional part can rotate relative to the mounting shaft, and there are two tools symmetrically arranged at the center, after the flipping locking device releases the connection between the connecting part and the functional part, the functional part can first be moved away from the upper surface of the placement seat until the lower end of the connecting slide hole in the length direction abuts the mounting shaft. Then, the functional part is rotated 180° around the mounting shaft, and then moved closer to the upper surface of the placement seat until the upper end of the connecting slide hole in the length direction abuts the mounting shaft. Finally, the flipping locking device fixes the functional part to the connecting part, thereby achieving the purpose of swapping the positions of the two tools. Compared with the method of having only one tool on the slide plate, this design allows the two tools to be of the same specification, so one tool can serve as a spare for the other tool to deal with unexpected situations in actual production. Similarly, different specifications can also be selected, thereby improving the practicality of the entire fixture.

[0031] Preferably, the two cutting tools are divided into a first functional group and a second functional group. The second mounting base connected to the first functional group cannot move along the axial direction of the first connecting shaft. The first functional group is used to accommodate multiple through slots that are sequentially distributed with the first limiting plate as the starting point. The second mounting base connected to the second functional group can move along the axial direction of the first connecting shaft. The second mounting base connected to the second functional group is also connected to an axial adjustment component. The second functional group is used to accommodate multiple through slots that are gradually distributed outward from the midpoint of the workpiece size.

[0032] By adopting the above technical solution, when the workpiece has different numbers of through slots distributed sequentially starting from the first limiting plate, the cutter of the first functional group can be selected to deburr the workpiece. When workpieces of different specifications need to be placed on the placement seat, they only need to be in contact with the first and second limiting plates, thus enabling faster deburring of workpieces of different specifications under this type. When the workpiece has multiple through slots gradually distributed outward from the midpoint of its own size, the distance between the middle of the blade in the second functional group and the first limiting plate can be adjusted by the axial adjustment component, thus enabling deburring of workpieces of different specifications under this type. In summary, the practicality of the entire fixture can be improved, so that the fixture can adapt to more different production conditions.

[0033] Preferably, the axial adjustment assembly includes:

[0034] An extension shaft has one end rotatably mounted on the second mounting base, and the other end located outside the second mounting base;

[0035] The drive gear is rotatably mounted on the extension shaft;

[0036] A driven gear is rotatably connected to the slide plate. The driven gear has a larger gear than the driving gear, and the driven gear meshes with the driving gear.

[0037] A spatial cam is fixedly connected to one end face of the driven gear, and a guide groove in the shape of a closed ring is provided around the outer peripheral wall of the spatial cam.

[0038] One end of the guide rod is connected to the second mounting base, and the other end is movably inserted into the guide groove.

[0039] By adopting the above technical solution, when adjusting the position of the second mounting seat on the first connecting shaft, the drive gear is rotated first, and then the drive gear drives the driven gear to rotate. Then the guide groove on the space cam will match the guide rod so that the entire second mounting seat moves along the axial direction of the first connecting shaft, thereby changing the distance between the middle of the blade and the first limiting plate, and thus achieving the purpose of adapting the second functional group to the workpiece with multiple through slots gradually distributed outward from the center of the workpiece size.

[0040] In summary, this application includes at least one of the following beneficial technical effects:

[0041] 1. By setting up a mounting base, positioning components, slide plate, and cutting tool, compared to the manual deburring process of each through groove of the workpiece using a deburring tool, this design method can improve the efficiency of deburring by allowing the cutting tool to simultaneously work on multiple through grooves on the workpiece, and by eliminating the need for the workpiece to constantly change its posture during the movement of the cutting tool.

[0042] 2. By using a positioning component including a first limiting plate and a second limiting plate, the workpiece can be stably placed on the predetermined position on the upper surface of the placement seat simply by having two adjacent side surfaces of the workpiece abut against the first limiting plate and the second limiting plate respectively.

[0048] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0049] This application discloses a deburring fixture. (Refer to...) Figure 1 The deburring fixture includes a placement seat 1, a positioning component 2, a sliding plate 3, and a cutting tool 4. The placement seat 1 is rectangular in shape, and the upper surface of the placement seat 1 is for placing the workpiece. The positioning component 2 is disposed on the upper surface of the placement seat 1, and after the workpiece is placed on the upper surface of the placement seat 1, the workpiece can be adjusted to a predetermined position by the positioning component 2. The sliding plate 3 is slidably connected to the placement seat 1, and the sliding direction of the sliding plate 3 is parallel to the length direction of the through groove on the workpiece. The cutting tool 4 is connected to the sliding plate 3, and the cutting tool 4 has multiple cutting edges to cooperate with multiple through grooves on the workpiece. After the workpiece is fixed in the predetermined position of the placement seat 1, the cutting tool 4 can be moved along the length direction of the through groove on the workpiece by moving the sliding plate 3. After the sliding plate 3 completes one reciprocating movement, the deburring process of the workpiece is completed, thereby processing multiple through grooves on the workpiece at the same time, which helps to improve the efficiency of deburring.

[0050] Reference Figure 1Because the structure of the positioning component 2 is related to the movement of the slide plate 3, for ease of description, in this embodiment, the starting point and ending point of the movement path of the slide plate 3 will be set as the processing starting point 5 and the processing ending point 51, respectively. Specifically, the positioning component 2 includes a first limiting plate 21 and a second limiting plate 22. The first limiting plate 21 is fixedly connected to the upper surface of the placement seat 1 by bolts, and the length direction of the first limiting plate 21 is parallel to the movement direction of the slide plate 3. Moreover, the first limiting plate 21 will abut against one side surface of the workpiece. The second limiting plate 22 is also fixedly connected to the upper surface of the placement seat 1 by bolts, and the length direction of the second limiting plate 22 is perpendicular to the movement direction of the slide plate 3. Moreover, the second limiting plate 22 also abuts against the other side surface adjacent to the workpiece. At the same time, the second limiting plate 22 is also close to the location of the processing ending point 51. Therefore, during the reciprocating movement of the slide plate 3, the workpiece will be less likely to move away from the second limiting plate 22 under the action of the friction between the second limiting plate 22 and the placement seat 1. Thus, the positioning and holding of the workpiece position can be achieved through a simple structure.

[0051] Reference Figure 1 The upper surface of the placement base 1 has two parallel and spaced rectangular uprights 11 fixed. Between the two uprights 11 are two parallel and spaced mounting guide rods 12. The axis of the mounting guide rods 12 is parallel to the direction of movement of the slide plate 3. Specifically, each mounting guide rod 12 is slidably fitted with multiple connecting sleeves 13, distributed along the axis of the mounting guide rod 12. Each connecting sleeve 13 has multiple ball bearings embedded on its outer periphery. The two ends of the slide plate 3 are respectively fitted onto the connecting sleeves 13 of the two mounting guide rods 12. This enables a sliding connection between the slide plate 3 and the placement seat 1, and also makes the sliding of the slide plate 3 smoother. In addition, in this embodiment, a return spring 14 is sleeved on the part of the mounting guide rod 12 near the processing end point 51. One end of the return spring 14 is fixedly connected to the stand 11 near the processing end point 51, and the other end abuts against one end of the connecting sleeve 13 near the processing end point 51. Therefore, the return spring 14 can apply a force to the slide plate 3 towards the processing start point 5 through the connecting sleeve 13, so that the operator can return the slide plate 3 to its original position with less effort.

[0052] Reference Figure 1 and Figure 2A first mounting base 6 and a second mounting base 7 are provided at the connection between the slide plate 3 and the tool 4. The first mounting base 6 is fixedly connected to the slide plate 3, and a first connecting groove 61 is provided on the first mounting base 6. The first connecting groove 61 is vertically oriented, and a cylindrical first connecting shaft 62 is connected between the two opposite side walls of the first connecting groove 61. One end of the second mounting base 7 is rotatably sleeved on the first connecting shaft 62, and the other end is connected to the tool 4. When the slide plate 3 moves towards the processing endpoint 51, the friction between the tool 4 and the workpiece will cause the end of the second mounting base 7 away from the first connecting shaft 62 to be slightly pressed down, thereby more fully deburring the workpiece. When the slide plate 3 moves towards the processing start point 5, the friction between the tool 4 and the workpiece will cause the end of the second mounting base 7 away from the first connecting shaft 62 to be slightly tilted up, thereby preventing the tool 4 from scratching the workpiece.

[0053] Reference Figure 2 and Figure 3 The second connecting groove 71 is provided at one end away from the first connecting shaft 62. The connecting direction of the second connecting groove 71 is vertical. A cylindrical second connecting shaft 72 is fixedly connected to the two opposite side walls of the second connecting groove 71 to serve as the basic connection structure between the tool 4 and the second mounting base 7. Specifically, the tool 4 includes a connecting post 41, an unlocking spring 42, a connecting magnet 43, a blade 44, an abutment block 45, a spacer ring 46, and a rotation limiting member 47. The connecting post 41 is rotatably sleeved on the second connecting shaft 72, and the outer peripheral wall of the connecting post 41 is provided with... The device is provided with a mounting groove 411, and multiple mounting grooves 411 are evenly distributed around the axis of the connecting post 41. One end of the unlocking spring 42 is fixedly connected to the bottom of the mounting groove 411. The connecting magnet 43 is slidably connected in the mounting groove 411, and the other end of the connecting magnet 43 is fixedly connected to the unlocking spring 42. The sliding direction of the connecting magnet 43 is parallel to the opening direction of the mounting groove 411. One end of the blade 44 is attracted to the connecting magnet 43, and the other end can enter and exit the opening of the mounting groove 411 under the action of the unlocking spring 42. At the same time, the blade 44 is also aligned with the end of the connecting magnet 43 near the first limiting plate 21.

[0054] Reference Figure 2 and Figure 3The abutment block 45 is fixedly connected to the connecting magnet 43, and the abutment block 45 is located on the end of the connecting magnet 43 away from the first limiting plate 21; the partition ring 46 is circular in shape, and the partition ring 46 is fixedly connected to the second mounting base 7. When the partition ring 46 abuts against the abutment block 45, the end of the blade 44 away from the connecting magnet 43 will retract into the mounting groove 411. At the same time, the partition ring 46 also has an unlocking notch 461 so that the end of the blade 44 away from the connecting magnet 43 can slide out of the mounting groove 411, thereby realizing the opening and closing of the blade 44.

[0055] Reference Figure 2 and Figure 3 To accommodate the rotation limiting member 47, a receiving groove 73 is provided at the bottom of the second connecting groove 71. Specifically, the rotation limiting member 47 includes a limiting wheel 471, a limiting pin 472, and a limiting spring 473. The limiting wheel 471 is fixedly connected to one end of the connecting post 41, and a limiting groove 10 is provided on the outer circumferential wall of the limiting wheel 471. The cross-section of the limiting groove 10 along the communication direction is semi-circular, and multiple limiting grooves 10 are distributed around the axis of the limiting wheel 471. One end of the limiting pin 472 is slidably disposed in the receiving groove 73, and the other end is adapted to be inserted into the limiting groove. In section 10, a limiting spring 473 is disposed in the receiving groove 73 and is connected to a limiting pin 472. When the connecting column 41 rotates, the limiting pin 472 will directly move towards the bottom of the receiving groove 73 and forcefully disengage from the limiting through groove 10. Then, the limiting pin 472 will abut against the outer wall of the limiting wheel 471 where the limiting through groove 10 is not provided. When the limiting pin 472 moves to the next limiting through groove 10, the limiting pin 472 will be inserted into the limiting through groove 10 again under the action of the limiting spring 473, so that the connecting column 41 can be automatically locked after rotating to the predetermined posture.

[0056] Reference Figure 1 and Figure 2In this embodiment, the slide plate 3 includes two connecting parts 31, a functional part 32, and a flip-locking component. Specifically, the two connecting parts 31 are spaced apart and are respectively connected to two mounting guide rods 12. A cylindrical mounting shaft 311 is also installed at the gap between the two connecting parts 31. The functional part 32 is used for mounting the cutter 4, and an oval-shaped connecting sliding hole 321 is provided on the functional part 32. The length direction of the connecting sliding hole 321 is vertical, and the connecting... The sliding hole 321 also allows the mounting shaft 311 to pass through. When it is necessary to flip the functional part 32, the functional part 32 is first moved upward until the mounting shaft 311 abuts against the lower end of the connecting sliding hole 321. Then the functional part 32 is rotated 180° and then moved downward until the mounting shaft 311 abuts against the upper end of the connecting sliding hole 321. The flipping locking member can be a combination of square plate and bolts. After the functional part 32 is flipped 180° as a whole, the flipping locking member locks the functional part 32 onto the connecting part 31.

[0057] Reference Figure 2 and Figure 4 In this embodiment, two cutting tools 4 are provided. The two cutting tools 4 are centrally symmetrically arranged on the functional unit 32 with respect to the mounting shaft 311. At the same time, the two cutting tools 4 correspond to different application scenarios. Specifically, the two cutting tools 4 are respectively in the first functional group 8 and the second functional group 81. The cutting tools 4 in the first functional group 8 are adapted to workpieces with multiple through slots distributed with the first limiting plate 21 as the starting point. In this case, the cutting tools 4 in the first functional group 8 only need to select the blade 44 according to the number of through slots on the workpiece. The cutting tools 4 in the second functional group 81 are adapted to workpieces with multiple through slots distributed outward from the middle position of the workpiece itself. In this case, the cutting tools 4 in the second functional group 81 need to select the blade 44 according to the number of through slots on the workpiece, and at the same time, the distance between the middle of the blade 44 and the first limiting plate 21 needs to be changed to adapt to this type of workpiece.

[0058] Reference Figure 2 and Figure 4The second mounting base 7, connected to the second functional group 81, can move along the axial direction of the first connecting shaft 62. The second functional group 81 is also connected to an axial adjustment assembly 9. Specifically, the axial adjustment assembly 9 includes an extension shaft 91, a drive gear 92, a driven gear 93, a spatial cam 94, and a guide rod 95. The extension shaft 91 rotatably passes through the second mounting base 7, with its other end outside the second mounting base 7. The extension shaft 91 is also coaxially arranged with the second connecting shaft 72. The drive gear 92 is coaxially rotatably sleeved on the extension shaft 91. The driven gear 93 is rotatably connected to the functional part 32 and meshes with the drive gear 92. The tooth thickness of the driven gear 93 is greater than that of the drive gear 92, so that the driven gear 93 and the drive gear 92 remain meshed when the second mounting base 7 moves.

[0059] Reference Figure 2 and Figure 4 The spatial cam 94 is coaxially fixedly connected to one end of the driven gear 93, and a closed-ring guide groove 941 is provided on the outer wall of the spatial cam 94, which surrounds the periphery of the spatial cam 94. One end of the guide rod 95 is fixedly connected to the second mounting base 7, and the other end is movably inserted into the guide groove 941. When the second mounting base 7 is to be moved, the driving gear 92 is rotated first, and then the driven gear 93 will drive the spatial cam 94 to rotate. During this process, the end of the guide rod 95 connected to the spatial cam 94 will move along the axis of the spatial cam 94, which will drive the second mounting base 7 to move along the axis of the first connecting shaft 62, thereby changing the distance between the middle of the blade 44 and the first limiting plate 21.

[0060] The implementation principle of a deburring fixture in this application embodiment is as follows: When deburring is required for a workpiece, the workpiece is first placed on the upper surface of the placement seat 1, and the workpiece abuts against the first limiting plate 21 and the second limiting plate 22. Then, the sliding plate 3 is moved to complete one reciprocating movement from the processing start point 5 to the processing end point 51, thereby completing the deburring of the through grooves on the workpiece. Compared with the manual deburring method of each through groove of the workpiece by using a deburring knife, this design method allows the tool 4 to process multiple through grooves on the workpiece at the same time. In addition, the workpiece does not need to change its posture constantly during the movement of the tool 4, thereby improving the efficiency of deburring.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
