Description

Technical Field

[0001] This invention relates to a processing device with a magnetic table, and more particularly to a processing device with a magnetic table that can accurately position itself in the front-back direction and quickly switch between magnetic tables. Background Technology

[0002] A processing device for processing parts includes a magnetic table, on which the part is adsorbed and fixed on the upper surface of the magnetic table, and a fixed seat is fixed on the machine tool. The fixed seat is located below the magnetic table and is fixedly connected to the magnetic table by bolts, so that the magnetic table and the part are fixed on the machine tool. When processing the part, such as grooving the part, the worktable can move back to the left, thereby driving the magnetic table and the part to move back to the left and right, which facilitates the processing of grooving and other processes on the part.

[0003] However, since the magnetic platform and the mounting base are fixedly connected by bolts, when the magnetic platform needs to be replaced, the bolts that were originally fixed between the magnetic platform and the mounting base must be removed, and then the new magnetic platform and the mounting base must be locked in place using bolts. This requires repeated disassembly and installation of the bolts, which not only makes the replacement of the magnetic platform more complicated, but may also cause the bolts to loosen and rotate in the front-back direction. Moreover, due to installation errors, the installation position of the replaced magnetic platform in the front-back direction will be offset compared to the installation position of the previous magnetic platform in the front-back direction. This will lead to inaccurate positioning of the magnetic platform, which in turn will lead to inaccurate positioning of the parts adsorbed on the magnetic platform, resulting in poor part processing.

[0004] Therefore, it is necessary to design a new processing equipment with a magnetic stage to overcome the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a stopping member mounted on a limiting block of a fixed base, a positioning frame fixedly connected below a magnetic table, and a positioning block extending downward from the positioning frame with an inclined surface. A second pushing member of a sliding component slides on the inclined surface to push the positioning block, thereby clamping the positioning block between the stopping member and the second pushing member of the sliding component in the front-back direction. Then, by sliding the sliding component back, the sliding component gradually releases the pushing force on the positioning block, thus facilitating the replacement of the magnetic table in an automated production line.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A processing device with a magnetic table, characterized in that it comprises: the magnetic table; a positioning frame, fastened to the magnetic table and located below the magnetic table, with at least one positioning block extending downward from the positioning frame, the positioning block having an inclined surface; a fixed base fixed to the machine platform, the upper surface of the fixed base having at least one recessed receiving groove extending in a left-right direction, the fixed base having an abutment block and at least two parallel limiting blocks integrally formed on the front and rear sides of the receiving groove, the two limiting blocks jointly limiting the left and right sides of the positioning block; a stop member fixedly installed on the two limiting blocks to stop the positioning block from displacing along the side away from the abutment block; at least one power mechanism and a sliding member connected to the power mechanism, the power mechanism being fixed to the fixed base, the sliding member being disposed in the receiving groove and capable of reciprocating from an initial position to a final position in a left-right direction. The sliding member has at least one first pusher that can slide along the surface of the abutment block and a second pusher that can slide along the inclined surface of the positioning block. The second pusher and the first pusher are arranged in a vertical direction. When the power mechanism pushes the sliding member from an initial position to a lateral position, the first pusher contacts the abutment block and slides on the surface of the abutment block to press against the abutment block in a front-back direction. The second pusher contacts the inclined surface and slides along the inclined surface to gradually push the positioning block toward the stop, so that the positioning block is locked between the stop and the second pusher in a front-back direction. When the power mechanism pulls the sliding member back to the initial position, the second pusher slides back on the inclined surface and gradually releases the pushing force on the positioning block until the positioning block is unlocked between the stop and the second pusher.

[0008] Furthermore, the abutment block has a recessed relief groove on the side near the second pusher, the side of the second pusher near the abutment block is located in the relief groove and has a gap with the side wall of the relief groove, and the other side of the second pusher slides in contact with the inclined surface.

[0009] Furthermore, the limiting block is located on the front side of the receiving groove, and the positioning block protrudes rearward from the rear surface of the limiting block. When the power mechanism pushes the sliding member to slide, the first pushing member always has a gap with the inclined surface, and the gap between the second pushing member and the inclined surface gradually narrows until the second pushing member abuts against the inclined surface, and pushes the positioning block to move towards the stop member.

[0010] Furthermore, both the first and second pushers are bearings, and there are two first pushers, which are located on the upper and lower sides of the second pusher, respectively. The first and second pushers are coaxially arranged, and the diameter of the second pusher is larger than the diameter of the first pusher.

[0011] Furthermore, the sliding member is provided with a guide block located below the first pusher and the second pusher. A guide groove is provided below the receiving groove and extends vertically through it. When the sliding member slides, the guide block is located in the guide groove and moves horizontally.

[0012] Furthermore, the lower surface of the positioning frame is provided with at least one first protrusion protruding downwards, and the upper surface of the limiting block is provided with at least one second protrusion protruding upwards corresponding to the first protrusion. The sliding member protrudes upwards from the second protrusion. When the positioning frame drives the magnetic platform to be installed on the fixed base, the first protrusion and the second protrusion abut against each other, and there is a gap between the sliding member and the lower surface of the positioning frame.

[0013] Furthermore, each of the limiting blocks is provided with a through hole in the left-right direction, and the stop is a rigid pin. The two ends of the stop are respectively tightly engaged with the through holes of the two limiting blocks. When the positioning block is locked between the stop and the second pusher, the middle part of the stop is aligned with the second pusher, and the middle part of the stop is rigidly abutting against the positioning block.

[0014] Furthermore, a locking member and at least one limiting block are fixedly installed on the lower surface of the positioning frame, and a mating fastener is fixedly installed on the upper surface of the fixing seat corresponding to the locking member. One of the limiting blocks extends outward beyond the abutting block in the left-right direction. When the positioning frame is installed on the fixing seat, the locking member and the mating fastener are locked together to limit the positioning frame in the up-down direction. The abutting block limits the limiting block in the left-right direction, and the limiting block limits the limiting block in the front-back direction.

[0015] Furthermore, the magnetic platform has at least one clamping groove on each of its two sides along the left-right direction, the clamping groove being used for gripping by a robotic arm, and the positioning frame having multiple material removal holes penetrating along the up-down direction, with the magnetic platform covering the top of the material removal holes.

[0016] Furthermore, it further includes a dust cover, which comprises an upper cover and a lower cover that are nested and fixed to each other. The upper cover is fixed to the positioning frame and covers the perimeter of the positioning frame. The lower end of the lower cover is fixed to the machine platform and the side walls of the lower cover extend upward to cover the perimeter of the fixed base.

[0017] Compared with the prior art, the electrical connector assembly of the present invention has the following advantages:

[0018] In this invention, a positioning frame is mounted below and securely connected to the magnetic platform. The positioning frame also extends downwards with a positioning block having an inclined surface. A fixed base is fixed to the equipment platform, and the fixed base has abutment blocks and two limiting blocks formed on its front and rear sides of the receiving groove, respectively. When the positioning frame and the magnetic platform are installed together on the fixed base, the two limiting blocks jointly limit the left and right sides of the positioning block, thus limiting the positioning frame and the magnetic platform in the left and right directions. A stop is installed on the two limiting blocks. A power mechanism pushes a sliding member from its initial position to its final position in the left and right directions. The first pushing member slides on the surface of the abutment block and presses against the abutment block in the front and back directions. The second pushing member slides along the inclined surface to gradually push the positioning block towards the stop, gradually increasing the pushing force on the positioning block until the positioning block presses against the stop in the front and back directions. The stop and lock are locked between the stop and the second pusher; this allows the positioning frame and magnetic table to be accurately installed on the fixed seat in the front-back direction and to be automatically locked, thus ensuring that the parts can be processed accurately. When the magnetic table needs to be replaced, the power mechanism only needs to pull the sliding component back, and the second pusher will slide back on the inclined surface and gradually release the pushing force on the positioning block until the positioning block is unlocked between the stop and the second pusher. At this time, the positioning frame and magnetic table can be directly removed without repeatedly tightening and unlocking the bolts, which makes the replacement of the magnetic table simple. This facilitates the replacement of magnetic tables in automated production lines and also ensures that the newly replaced positioning frame and magnetic table can be quickly and accurately positioned on the fixed seat in the front-back direction, thereby enabling the parts adsorbed on the magnetic table to be quickly and accurately positioned, reducing the defect rate of processed parts.

Detailed Implementation Methods

[0031] To facilitate a better understanding of the purpose, structure, features, and effects of this invention, a processing device with a magnetic table 1 will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 10 As shown, the processing equipment with a magnetic table 1 of the present invention defines a front-back direction, a left-right direction perpendicular to the front-back direction, and a top-bottom direction. For ease of understanding of the drawings, the forward direction in the front-back direction is taken as the positive direction of the X-axis, the rightward direction in the left-right direction is taken as the positive direction of the Y-axis, and the upward direction in the top-bottom direction is taken as the positive direction of the Z-axis.

[0033] like Figures 1 to 10As shown, this invention discloses a processing device with a magnetic table 1. This processing device has a processing component (not shown, the same below) for processing a part (not shown, the same below). In this embodiment, the processing device is a grinding machine, and the corresponding processing component is a grinding wheel (not shown, the same below). Of course, in other embodiments, the processing device can also be a milling machine, a lathe, or other equipment for processing parts, and the corresponding processing component can be a milling cutter, a turning tool, or other components for processing parts. A processing device with a magnetic table 1 includes: a magnetic table 1, a part adsorbed and fixed on the upper surface of the magnetic table 1, and a positioning frame 2 securely connected to the magnetic table 1 and located below the magnetic table 1. The positioning frame 2 and the magnetic table 1 are fixedly connected by bolts, and the positioning frame 2 is disassembled and replaced along with the magnetic table 1 when the magnetic table 1 is replaced. A fixed base 4 is fixed on the equipment platform (not shown, the same below), and at least one power mechanism 5 (in this embodiment, there are two power mechanisms 5, but in other embodiments, the number of power mechanisms 5 can be one, three, etc.) is fixed on the fixed base 4. Each power mechanism 5 is also connected to a sliding member 6. The fixed base 4, the power mechanism 5 and the sliding member 6 fix the positioning frame 2 and the magnetic table 1 on the equipment platform, thereby fixing the parts on the equipment platform for easy processing of the parts.

[0034] like Figure 1 and Figure 2 As shown, the magnetic table 1 is plate-shaped (of course, in other embodiments, the shape of the magnetic table 1 can be trapezoidal or other shapes), and the magnetic table 1 is similar to the magnetic table on a conventional grinding machine, both of which are used to adsorb parts. In this embodiment, the upper surface of the magnetic table 1 is used to adsorb and fix the parts, and its lower surface is provided with multiple screw holes (not shown, the same below), so that screws (not shown, the same below) can be inserted into the screw holes to fix the positioning frame 2 under the magnetic table 1. The magnetic table 1 is provided with at least one clamping groove 11 on each of its two sides along the left and right directions. In this embodiment, the left and right sides of the magnetic table 1 are provided with two clamping grooves 11 respectively (of course, in other embodiments, the clamping grooves 11 can also be provided on the front and rear sides of the magnetic table 1, and the number of clamping grooves 11 can be one, three, etc.). The clamping grooves 11 are used for the clamping protrusions 11' of a robot arm 1' to extend into, thereby facilitating the robot arm 1' to clamp the magnetic table 1.

[0035] like Figure 1 , Figure 2 , Figure 7 , Figure 8 and Figure 10 As shown, the positioning frame 2 is plate-shaped, and it also has multiple screw holes (unnumbered, the same below) along its vertical direction. Some of these screw holes correspond one-to-one with the screw holes of the magnetic platform 1, allowing screws to be inserted to fix the positioning frame 2 and the magnetic platform 1. At least one positioning block 21 extends downwards from the positioning frame 2 (in this embodiment, there are two positioning blocks 21; however, in other embodiments, the number of positioning blocks 21 can be one, three, etc.). Figure 7and Figure 8 As shown, each positioning block 21 has an inclined surface 211, which is used to cooperate with the sliding member 6. Figure 10 As shown, the lower surface of the positioning frame 2 is also provided with at least one first protrusion 22 protruding downward. In this embodiment, there are three first protrusions 22, two of which are adjacent to two positioning blocks 21 respectively, and the other first protrusion 22 is located behind the two first protrusions 22 (of course, in other embodiments, the number of first protrusions 22 can be two, four, etc.).

[0036] like Figure 1 , Figure 2 , Figure 7 , Figure 8 and Figure 10 As shown, a locking member 3 and at least one limiting block 23 are also fixed to the lower surface of the positioning frame 2 by bolts. The locking member 3 has a locking post 31, and a locking groove 311 is recessed in the circumference of the locking post 31. There are four limiting blocks 23 (of course, in other embodiments, the number of limiting blocks 23 can also be two, etc.). The four limiting blocks 23 are respectively installed at the four corners of the positioning frame 2. The limiting blocks 23 are used to cooperate with the fixed base 4 to limit and stop the positioning frame 2 and the magnetic table 1 in the front-back direction and the left-right direction. The positioning frame 2 also has a plurality of material removal holes 24 extending in the vertical direction. The material removal holes 24 can reduce the weight of the positioning frame 2, making it easier to move when replacing the magnetic table 1 and the positioning frame 2. The magnetic table 1 is covered above the material removal holes 24, thus preventing waste and dust from the processed parts from entering between the fixed base 4 and the positioning frame 2 through the material removal holes 24.

[0037] like Figure 2 , Figure 5 and Figure 9As shown, the upper surface of the fixing base 4 is recessed downwards with at least one receiving groove 41. In this embodiment, there are two receiving grooves 41, which are spaced apart in the left-right direction, and each receiving groove 41 extends in the left-right direction. The fixing base 4 has an abutment block 42 and at least two limiting blocks 43 arranged side by side integrally formed on the front and rear sides of the receiving groove 41, respectively. In this embodiment, the abutment block 42 is located on the rear side of the two receiving grooves 41, and two limiting blocks 43 are provided on the front side of each receiving groove 41. The two limiting blocks 43 located directly in front of any receiving groove 41 together limit the left and right sides of one of the positioning blocks 21. Each limiting block 43 has a through hole 431 extending in the left-right direction. A stop 44 is installed in the through holes 431 of the two limiting blocks 43 directly in front of each receiving groove 41. The stop 44 is a rigid pin (in other embodiments, the stop 44 can also be other rigid components with curved surfaces). The two ends of the stop 44 are tightly engaged with the through holes 431 of the two limiting blocks 43 respectively. The stop 44 is used to prevent the positioning block 21 from moving away from the abutment block 42. A guide groove 45 is provided below the receiving groove 41 and communicates with it vertically. There is one guide groove 45. The guide groove 45 is located below the two receiving grooves 41 and communicates with the two receiving grooves 41 vertically. The guide groove 45 extends in the left-right direction and passes through the fixing seat 4 in the left-right direction. The guide groove 45 is used to guide the sliding member 6 to slide in the left-right direction. Two clearance grooves 421 are provided on the side of the abutment block 42 near the receiving groove 41 (i.e. the front side of the abutment block 42), and the clearance grooves 421 are used to provide clearance for the sliding member 6.

[0038] like Figure 2 , Figure 7 , Figure 8 and Figure 9 As shown, the outermost limiting block 43 extends beyond the abutment block 42 in the left-right direction. When the positioning frame 2 is installed on the fixed base 4, the abutment block 42 restricts the limiting block 43 in the left-right direction, and the limiting block 43 restricts the limiting block 23 in the front-back direction. Specifically, in this embodiment, the leftmost limiting block 43 extends beyond the abutment block 42 to the left, and the rightmost limiting block 43 extends beyond the abutment block 42 to the right. When the positioning frame 2 is installed on the fixed base 4, the left wall of the abutment block 42 is used to restrict the leftward displacement of the limiting block 23 located on the left front side, and the leftmost limiting block 43 is used to restrict the forward displacement of the limiting block 23 located on the left front side. Similarly, the right wall of the abutment block 42 is used to restrict the rightward displacement of the limiting block 23 located on the right front side, and the rightmost limiting block 43 is used to restrict the forward displacement of the limiting block 23 located on the right front side.

[0039] like Figure 2 and Figure 9As shown, a support block 46 is integrally formed on the upper surface of the fixing base 4. The support block 46 is located behind the abutment block 42, and the support block 46 is at the same height as the limiting block 43. The support block 46 is used to support the positioning frame 2 and the magnetic platform 1 upward. A notch 461 is provided on the left and right sides of the support block 46. The two notches 461 are used to accommodate two limiting blocks 23, thereby blocking and limiting the two limiting blocks 23 located on the rear side in the left and right directions and the rear side.

[0040] like Figure 2 and Figure 9 As shown, the fixed base 4 is provided with three second protrusions 47 corresponding to the three first protrusions 22. Two of the second protrusions 47 are formed by protruding from the upper surfaces of the leftmost limiting block 43 and the rightmost limiting block 43 in the left-right direction, respectively. The other second protrusion 47 is formed by protruding from the upper surface of the support block 46. The sliding member 6 protrudes upward from the second protrusions 47. When the positioning frame 2 drives the magnetic table 1 to be installed on the fixed base 4, the first protrusions 22 and the second protrusions 47 abut against each other, and there is a gap between the sliding member 6 and the lower surface of the positioning frame 2.

[0041] like Figure 2 , Figure 7 , Figure 8 and Figure 9 As shown, there are two power mechanisms 5 and two sliding members 6 (of course, in other embodiments, the number of power mechanisms 5 and sliding members 6 can be one, three, etc.). In this embodiment, both power mechanisms 5 are push cylinders, and both sliding members 6 are slide rods. Both power mechanisms 5 are fixed to the fixed base 4, and the two power mechanisms 5 are arranged adjacent to each other in the left-right direction. The two sliding members 6 are respectively disposed in two receiving slots 41. Each power mechanism 5 is connected to its corresponding sliding member 6, and each power mechanism 5 can push the corresponding sliding member 6 to reciprocate from the initial position to the end position in the left-right direction.

[0042] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 9As shown, each sliding member 6 has at least one first pushing member 61 that can slide along the surface of the abutment block 42 and a second pushing member 62 that can slide along the inclined surface 211 of the positioning block 21. The second pushing member 62 and the first pushing member 61 are arranged in a vertical direction. In this embodiment, each sliding member 6 has two first pushing members 61 and one second pushing member 62, with the two first pushing members 61 located on the upper and lower sides of the second pushing member 62, respectively. Both the first pushing member 61 and the second pushing member 62 are bearings (of course, in other embodiments, the first pushing member 61 and the second pushing member 62 can also be wedge-shaped blocks with inclined surfaces, or balls, etc.), and the first pushing member 61 and the second pushing member 62 are coaxially arranged, and the diameter of the second pushing member 62 is larger than the diameter of the first pushing member 61. Each of the abutment blocks 42 has a recessed relief groove 421 on one side near each of the second pushers 62. The side of the second pusher 62 near the abutment block 42 is located in the relief groove 421 and has a gap with the side wall of the relief groove 421. The other side of the second pusher 62 slides in contact with the inclined surface 211 of the corresponding positioning block 21.

[0043] like Figure 2 , Figure 4 , Figure 5 As shown, each sliding member 6 is also provided with a guide block 63. The guide block 63 is located below the first pusher 61 and the second pusher 62. When the sliding member 6 slides, the guide block 63 is located in the guide groove 45 and moves in the left and right directions.

[0044] like Figure 2 and Figure 9 As shown, a fastener 7 is installed on the upper surface of the fixed base 4 corresponding to the locking member 3. The fastener 7 has a locking hole 71 and a locking bead (not shown, the same below) is provided in the locking hole 71. When the positioning frame 2 is installed on the fixed base 4, the locking member 3 and the fastener 7 are locked together. The locking pin 31 extends into the locking hole 71 and the locking bead extends into the locking groove 311, thereby fixing the positioning frame 2 and the magnetic table 1 on the fixed base 4 in the vertical direction.

[0045] like Figure 1 and Figure 2 As shown, a processing device with a magnetic table 1 further includes a dust cover 8. The dust cover 8 includes an upper cover 81 and a lower cover 82 that are nested and fixed to each other. The upper cover 81 is fixed to the positioning frame 2 by bolts and covers the perimeter of the positioning frame 2. The lower end of the lower cover 82 is fixed to the machine platform and the side walls of the lower cover 82 extend upward to cover the perimeter of the fixed base 4. In this way, the upper cover 81 and the lower cover 82 can cover the perimeter of the positioning frame 2 and the fixed base 4, which can prevent processing waste and dust from entering between the positioning frame 2 and the fixed base 4 from the perimeter, thereby interfering with the sliding of the sliding member 6.

[0046] like Figure 2 , Figure 4 , Figure 5 , Figure 7 Figure 9 and Figure 10 As shown, when the positioning frame 2 and the magnetic platform 1 are installed and fixed on the fixed base 4, the two positioning blocks 21 extend into the space between their corresponding adjacent limiting blocks 43, so that the two limiting blocks 43 together limit the left and right sides of the corresponding positioning block 21, thus restricting the displacement of the positioning frame 2 and the magnetic platform 1 in the left and right directions. The locking pin 31 of the locking member 3 extends into the locking hole 71 of the mating fastener 7, and the locking ball is engaged in the locking groove 311, thereby restricting the displacement of the positioning frame 2 and the magnetic platform 1 in the up and down directions. The two limiting blocks 23 located on the rear side are respectively limited in the two recesses 461 of the support block 46, and the two limiting blocks 23 located on the front side are respectively limited to the left and right by the abutment block 42. The limiting blocks 43 stop forward, thereby restricting the displacement of the positioning frame 2 and the magnetic platform 1 in the front and rear directions and the left and right directions. At the same time, the two ends of each stop member 44 are tightly engaged with the through holes 431 of the two limiting blocks 43, and the positioning block 21 protrudes backward from the rear surface of the limiting block 43. After this, the power mechanism 5 begins to push the corresponding sliding member 6 to slide. When the power mechanism 5 pushes the sliding member 6 to move from the initial position to the end position in the left-right direction, the guide block 63 of the sliding member slides in the guide groove 45. The first pushing member 61 contacts the front surface of the abutment block 42 and slides on the front surface of the abutment block 42 to press against the abutment block 42 in the front-back direction, that is, press against the abutment block 42 backward. Moreover, there is always a gap between the front side of the first pushing member 61 and the inclined surface 211. During the sliding process of the sliding member 6, the gap between the second pushing member 62 and the inclined surface 211 gradually decreases until ... The second pusher 62 contacts the inclined surface 211 and slides along the inclined surface 211 in the positive direction to gradually push the positioning block 21 against the stop 44, so that the second pusher 62 pushes the positioning block 21 to move towards the stop 44, thereby locking the positioning block 21 between the stop 44 and the second pusher 62 in the front-back direction. At this time, the second pusher 62 abuts against the inclined surface 211 of the positioning block 21, and the middle part of the stop 44 is aligned with the second pusher 62, and the middle part of the stop 44 rigidly abuts against the positioning block 21; thus, the positioning frame 2 and the magnetic table 1 are locked and positioned in the front-back direction.

[0047] like Figure 2 , Figure 4 , Figure 5 and Figure 8As shown, when replacing the magnetic platform 1 and the positioning frame 2, the power mechanism 5 pulls the sliding member 6 back to the initial position, and the second pushing member 62 slides in the opposite direction on the inclined surface 211 and gradually releases the pushing force on the positioning block 21 until the positioning block 21 unlocks between the stop member 44 and the second pushing member 62. Then, the gripping protrusion 11' of the robot arm 1' can be inserted into the gripping groove 11 to grip the magnetic platform 1 and the positioning frame 2. By positioning the positioning frame 2 and the magnetic platform 1 in the above manner, not only can the positioning frame 2 and the magnetic platform 1 be accurately positioned in the front-back direction, left-right direction, and up-down direction, thus enabling precise positioning of parts, but it also facilitates the replacement of the magnetic platform 1.

[0048] In summary, the processing equipment with a magnetic table 1 of the present invention has the following beneficial effects:

[0049] (1) The positioning frame 2 is located below the magnetic table 1 and is fastened to the magnetic table 1. The positioning frame 2 also extends downward to a positioning block 21 with an inclined surface 211. The fixed seat 4 is fixed to the machine platform. The fixed seat 4 has abutment blocks 42 and two limiting blocks 43 respectively formed on the front and rear sides of the receiving groove 41. When the positioning frame 2 and the magnetic table 1 are installed together on the fixed seat 4, the two limiting blocks 43 jointly limit the left and right sides of the positioning block 21. In this way, the positioning frame 2 and the magnetic table 1 can be limited in the left and right directions. The stop 44 is installed on the two limiting blocks 43. The power mechanism 5 pushes the sliding member 6 from the initial position to the end position in the left and right directions. The first push member 61 slides on the surface of the abutment block 42 and presses against the abutment block 42 in the front and back directions. The second push member 62 slides along the inclined surface 211 to gradually push the positioning block 21 towards the stop 44. During the sliding process, the pushing force on the positioning block 21 is gradually increased until the positioning block 21 is close to the stop 44. The positioning frame 2 and magnetic table 1 are pressed tightly against the stop 44 in the front-back direction and locked between the stop 44 and the second pusher 62. This allows the positioning frame 2 and magnetic table 1 to be accurately installed on the fixed base 4 in the front-back direction and to be automatically locked, thus ensuring that the parts can be processed accurately. When the magnetic table 1 needs to be replaced, the power mechanism 5 only needs to pull the sliding member 6 back, and the second pusher 62 will slide back on the inclined surface 211 and gradually release the pushing force on the positioning block 21 until the positioning block 21 is unlocked between the stop 44 and the second pusher 62. At this time, the positioning frame 2 and magnetic table 1 can be directly removed without repeatedly tightening and unlocking the bolts, making the replacement of the magnetic table 1 simple. This facilitates the replacement of the magnetic table 1 in the automated production line and also ensures that the newly replaced positioning frame 2 and magnetic table 1 can be quickly and accurately positioned on the fixed base 4 in the front-back direction, thereby enabling the parts adsorbed on the magnetic table 1 to be quickly and accurately positioned, reducing the defect rate of processed parts.

[0050] (2) The abutment block 42 is recessed with a relief groove 421 on the side near the second pusher 62. The side of the second pusher 62 near the abutment block 42 is located in the relief groove 421 and has a gap with the side wall of the relief groove 421. The other side of the second pusher 62 slides in contact with the inclined surface 211. This allows the second pusher 62 to move smoothly between the abutment block 42 and the two limiting blocks 43, thereby avoiding the situation where the abutment block 42 and the second pusher 62 abut against each other, causing the second pusher 62 to be stuck by the abutment block 42 during the movement and unable to slide smoothly on the positioning block 21 and continue to push against the positioning block 21.

[0051] (3) The limiting block 43 is located on the front side of the receiving groove 41, and the positioning block 21 protrudes backward from the rear surface of the limiting block 43. The inclined surface 211 is set on the rearward protruding part of the positioning block 21. When the power mechanism 5 pushes the sliding member 6 to slide, there is always a gap between the first pushing member 61 and the inclined surface 211. The gap between the second pushing member 62 and the inclined surface 211 gradually narrows until the second pushing member 62 stops sliding and abuts against the inclined surface 211. At this time, the pushing force of the second pushing member 62 on the positioning block 21 is the greatest, so that the positioning block 21 is tightly abutted. The stopper 44 not only allows a gap between the first pusher 61 and the second pusher 62 and the rear surface of the limiting block 43, but also allows a gap between the first pusher 61 and the inclined surface 211. This prevents the limiting block 43 from blocking the sliding of the first pusher 61 and the second pusher 62, and also prevents the positioning block 21 from blocking the sliding of the first pusher 61. As a result, the first pusher 61 can slide smoothly along the abutment block 42, and the second pusher 62 can also smoothly push against the positioning block 21, thereby accurately positioning the positioning frame 2 and the magnetic platform 1 in the front-back direction.

[0052] (4) Both the first pusher 61 and the second pusher 62 are bearings, and the two first pushers 61 are located on the upper and lower sides of the second pusher 62 respectively. The first pusher 61 and the second pusher 62 are coaxially arranged, and the diameter of the second pusher 62 is larger than the diameter of the first pusher 61. This allows the abutting member to push against the two first pushers 61 at the same time, thereby enabling the second pusher 62 to continuously approach and contact the inclined surface 211 and push against the positioning block 21, thereby ensuring that the positioning block 21 can be clamped by the stopper 44 and the second pusher 62 in the front-back direction.

[0053] (5) The guide block 63 is located below the first pusher 61 and the second pusher 62. The receiving groove 41 is provided with a guide groove 45 that is vertically connected to it. The guide groove 45 extends in the left and right direction. When the sliding member 6 slides, the guide block 63 is located in the guide groove 45 and moves in the left and right direction. This ensures that the sliding member 6 can move in a straight line along a fixed trajectory during the left and right sliding process, avoiding the deviation that would cause the first pusher 61 to fail to abut against the abutting block 42 and the second pusher 62 to fail to abut against the inclined surface 211.

[0054] (6) The lower surface of the positioning frame 2 is provided with a first protrusion 22 protruding downwards, and the upper surface of the limiting block 43 is provided with a second protrusion 47 protruding upwards corresponding to the first protrusion 22. The sliding member 6 protrudes upwards from the second protrusion 47. When the positioning frame 2 drives the magnetic table 1 to be installed on the fixed seat 4, the first protrusion 22 and the second protrusion 47 abut against each other, and there is a gap between the sliding member 6 and the lower surface of the positioning frame 2. This reduces the contact area between the positioning frame 2 and the fixed seat 4, thereby ensuring that the positioning frame 2 and the fixed seat 4 can be pressed together, avoiding the situation where the positioning frame 2 and the fixed seat 4 do not contact each other and thus tilting, which would cause the upper surface of the magnetic table 1 to tilt, thereby causing the part to tilt. The gap between the sliding member 6 and the lower surface of the positioning frame 2 also prevents the positioning frame 2 from pressing the sliding member 6 downwards. This not only avoids the sliding member 6 from being obstructed, but also avoids damage to the sliding member 6.

[0055] (7) The stop 44 is a rigid pin. The two ends of the stop 44 are tightly engaged with the through holes 431 of the two limit blocks 43 respectively. When the positioning block 21 is locked between the stop 44 and the second pusher 62, the middle part of the stop 44 is aligned with the second pusher 62, and the middle part of the stop 44 is rigidly abutting against the positioning block 21. Thus, the abutting surface of the stop 44 and the positioning block 21 is an arc surface. When the stop 44 and the positioning block 21 abut against each other, the positioning block 21 and the stop 44 can be in line contact, thus making it easy to determine that the positioning block 21 and the stop 44 are locked together, thereby ensuring that the positioning frame 2 can be accurately positioned in the front and rear directions.

[0056] (8) The positioning frame 2 and the fixed seat 4 are locked together by the locking member 3 and the fastener 7, so that the positioning frame 2 can be positioned in the vertical direction. The positioning frame 2 also has a limiting block 23. The limiting block 43 located on the outermost side of the fixed seat 4 extends outward beyond the abutting block 42 in the horizontal direction. When the positioning frame 2 is installed on the fixed seat 4, the abutting block 42 restricts the limiting block 43 in the horizontal direction, and the limiting block 43 restricts the limiting block 23 in the front-back direction. In this way, the positioning frame 2 can be limited in the horizontal direction and the front-back direction through the abutting block 42 and the limiting block 43, so that the positioning frame 2 and the magnetic table 1 can be positioned in the vertical direction, the front-back direction and the horizontal direction, so that the parts can be positioned in the vertical direction, the front-back direction and the horizontal direction.
