Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, and in particular to a tooling for clamping and pushing magnetic blocks. Background Technology

[0002] The magnet in a permanent magnet has the function of generating a magnetic field and is the core component of the permanent magnet. High field strength permanent magnets require a strong magnetic field, so the magnet has a large mass.

[0003] Currently, magnets are mostly installed manually, but this method has the following problems and drawbacks in actual operation: Magnets have strong magnetism, and when the magnet is about to be placed in the pole plate inlet, it will be subjected to a strong repulsive force. In addition, the gap between the magnet and the pole plate inlet and the upper and lower parts of the yoke is very small, making it difficult for the operator to place the magnet parallel to the upper and lower parts, making it difficult to place the magnet in place; at the same time, the repulsive force can cause great danger, such as the magnet flying out or flipping over. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a tooling for clamping and pushing magnetic blocks to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a tooling for clamping and pushing magnetic blocks, comprising: A long base plate, on which clamping components and pushing components are arranged correspondingly on the left and right sides; The clamping assembly includes a first clamping block, a second clamping block, and a first driving unit. The first clamping block is fixedly installed at one end of the long base plate. The first driving unit is provided on one side of the first clamping block. The movable end of the first driving unit is connected to the second clamping block, so that the first clamping block and the second clamping block are in a front-to-back corresponding relationship to clamp and fix the magnet. The pushing component includes a meshing rack, a gear, and a second drive unit. The rack is slidably positioned in front of the long base plate, and one end of it passes through the first drive unit and contacts the magnet. The second drive unit is connected to the gear to drive the gear to rotate, so as to convert the rotational motion into linear motion to push the rack out of the magnet.

[0006] Preferably, the clamping assembly further includes an assembly base plate, which is placed at the bottom of the first clamping block and the second clamping block to support the magnet.

[0007] Preferably, the first drive unit includes a support base plate, a sliding block, a spring, a washer, an eccentric shaft, and a rocker arm. The support base plate is fixedly installed on the long base plate and located on one side of the first clamping block. The sliding block is slidably connected to the rear of the support base plate, and a spring is also connected between the support base plate and the sliding block. The second clamping block is fixedly installed on the end face of the sliding block and corresponds to the front and rear of the first clamping block. A washer is embedded in the front of the sliding block. The front end of the support base plate is rotatably connected to the eccentric shaft. The side of the eccentric shaft abuts against the washer, and a rocker arm is also connected to the side of the eccentric shaft.

[0008] Preferably, one end of the rack passes through the support base plate, and a push plate is connected to the end of the rack, with the push plate positioned between the first clamping block and the second clamping block.

[0009] Preferably, the pushing assembly also includes a linear guide and a slider, with at least two sliders, which are bolted to the long base plate. One side of the linear guide is slidably connected to the slider, and a rack is fixedly installed in front of the linear guide.

[0010] Preferably, a protective shield is also included.

[0011] Preferably, the second drive unit includes a rotating handle and a rotating shaft. One end of the rotating shaft is connected to the rotating handle, and the other end extends through to the bottom of the protective cover and is rotatably connected to the protective cover. One end of the rotating shaft that extends through the protective cover passes through a gear and is fixedly connected to it. A limit sleeve, a gasket, and a limit ring are also provided at the connection between the rotating shaft and the top of the protective cover.

[0012] Preferably, flexible pads are attached to the opposite surfaces of the first clamping block and the second clamping block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model places the magnet between the first clamping block and the second clamping block, and uses the first driving unit to push the second clamping block toward the first clamping block so that the first clamping block can clamp and fix the magnet. Then, the second driving unit rotates the gear, causing the rack to move to the right, so as to push the clamped and fixed magnet into the inside of the disk for assembly. Through mechanical clamping and by using the method of converting rotational motion into linear motion for transfer and assembly, it replaces the traditional manual assembly method, which not only improves the assembly accuracy of the disk, but also effectively avoids the safety hazards caused by repulsive forces.

[0014] 2. The sliding block of this utility model applies a force perpendicular to the tangent plane to the cylindrical surface at the end of the eccentric shaft through the shim. This ensures that the eccentric shaft will not return to its original position even if it is subjected to force at the cylindrical end, giving the first drive unit a certain self-locking function. This effectively prevents loosening during the pushing process and ensures the stability of the magnet clamping. Attached Figure Description

Detailed Implementation

[0019] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0020] This utility model provides a tooling for clamping and pushing magnetic blocks, such as Figure 1-3 As shown, it includes: 1. Long base plate; 2. Clamping assembly; 3. Pushing assembly; 4. Protective cover.

[0021] Both the clamping assembly 2 and the pushing assembly 3 are mounted on the long base plate 1 and are arranged in a left-right correspondence.

[0022] Specifically, the clamping assembly 2 includes a first clamping block 21, a second clamping block 22, and a first driving unit 23. The first clamping block 21 is fixedly installed at one end of the long base plate 1. The first driving unit 23 is provided on one side of the first clamping block 21. The front end of the first driving unit 23 protrudes from the first clamping block 21, and the movable end of the first driving unit 23 is connected to the second clamping block 22, so that the first clamping block 21 and the second clamping block 22 are in a front-to-back corresponding relationship to cooperate in clamping and fixing the magnet.

[0023] Specifically, the pushing component 3 includes a meshing rack 31, a gear 32, and a second drive unit 33. The rack 31 is slidably placed in front of the long base plate 1, and one end of it passes through the first drive unit 23 and contacts the magnet. The second drive unit 33 is connected to the gear 32 to drive the gear 32 to rotate, so as to convert the rotational motion into linear motion to push the rack 31 out of the magnet.

[0024] During assembly, the magnet is placed between the first clamping block 21 and the second clamping block 22, and the first drive unit 23 pushes the second clamping block 22 toward the first clamping block 21 to cooperate with the first clamping block 21 to clamp and fix the magnet. Then, the second drive unit 33 rotates the gear 32, causing the rack 31 to move to the right to push the clamped magnet into the inside of the disk for assembly. Through mechanical clamping and by converting rotational motion into linear motion, the assembly is transferred, replacing the traditional manual assembly method. This not only improves the assembly accuracy of the disk but also effectively avoids the safety hazards caused by repulsive forces.

[0025] Furthermore, the clamping assembly 2 also includes an assembly base plate 24, which is placed at the bottom of the first clamping block 21 and the second clamping block 22 to support the magnet.

[0026] In this embodiment, the first drive unit 23 includes a support base plate 231, a sliding block 232, a spring 233, a washer 234, an eccentric shaft 235, and a rocker arm 236. The support base plate 231 is fixedly installed on the long base plate 1 and located on one side of the first clamping block 21. The sliding block 232 is slidably connected to the rear of the support base plate 231, and the spring 233 is also connected between the support base plate 231 and the sliding block 232. The second clamping block 22 is fixedly installed on the end face of the sliding block 232 and corresponds to the front and rear of the first clamping block 21. The washer 234 is embedded in the front of the sliding block 232. The front end of the support base plate 231 is rotatably connected to the eccentric shaft 235. The side of the eccentric shaft 235 abuts against the washer, and the side of the eccentric shaft 235 is also connected to the rocker arm 236.

[0027] When clamping and fixing, the rocker arm 236 can be rotated first. The rocker arm 236 drives the eccentric shaft 235 to rotate. Using the principle of eccentricity, it squeezes the eccentric shaft 234, thereby causing the sliding block 232 to move backward, that is, to drive the second clamping block 22 to move closer to the first clamping block 21 until the magnet is clamped.

[0028] It is worth noting that the force applied by the sliding block 232 to the cylindrical surface at the end of the eccentric shaft 235 through the shim 234 is perpendicular to the tangent. This means that even if the eccentric shaft 235 is subjected to force at the cylindrical end, it will not return to its original position. This gives the first drive unit 23 a certain self-locking function, thereby effectively preventing loosening during the pushing process and ensuring the stability of the magnet clamping.

[0029] Furthermore, one end of the rack 31 passes through the support base plate 231, and a push plate 34 is connected to the end of the rack 31. The push plate 34 is placed between the first clamping block 21 and the second clamping block 22. The push plate 34 moves synchronously with the rack 31 to push out the magnet, so as to avoid damage to the end face of the rack 31 when it comes into contact with the magnet.

[0030] In this embodiment, the pushing component 3 also includes a slider 35 and a linear guide rail 36. There are at least two sliders 35, which are bolted to the long base plate 1. One side of the linear guide rail 36 is slidably connected to the slider 35. The rack 31 is fixedly installed in front of the linear guide rail 36 so that the rack 31 can slide freely in front of the long base plate 1 through the cooperation between the slider 35 and the linear guide rail 36.

[0031] In this embodiment, the second drive unit 33 includes a rotating handle 331 and a rotating shaft 332. One end of the rotating shaft 332 is connected to the rotating handle 331, and the other end extends through to the bottom of the protective cover 4 and is rotatably connected to the protective cover 4. One end of the rotating shaft 332 that extends through the protective cover 4 passes through the gear 32 and is fixedly connected to it. A limiting sleeve 333, a gasket, and a limiting ring 335 are also provided at the connection between the rotating shaft 332 and the top of the protective cover 4. That is, the rotating shaft 332 is rotatably mounted on the protective cover 4 through the limiting sleeve 333, the gasket, and the limiting ring 335. In use, rotating the rotating handle 331 causes the rotating shaft 332 to rotate, thereby synchronously driving the gear 32 to rotate and drive the rack 31 to move.

[0032] In this embodiment, flexible pads are attached to the opposite surfaces of the first clamping block 21 and the second clamping block 22. The flexible pads can be made of soft plastic, rubber pads, elastic cloth, sponge, or other materials, and are used to protect the magnets from being clamped and damaged.

[0033] The working principle of this utility model: During clamping, the magnet is placed between the first clamping block 21 and the second clamping block 22, so that the mounting base plate 24 supports the magnet. Then, the rocker arm 236 is rotated, and the rocker arm 236 drives the eccentric shaft 235 to rotate. Using the principle of eccentricity, it squeezes 234, thereby causing the sliding block 232 to move backward, that is, to drive the second clamping block 22 to move closer to the first clamping block 21 until the magnet is clamped. During assembly, rotating the handle 331 causes the rotating shaft 332 to rotate, which in turn drives the gear 32 to rotate and drive the rack 31 to move. The push plate 34 moves synchronously with the rack 31 to push out the magnet until the magnet is pushed to the assembly position.
