Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, specifically to a tooling and fixture for processing micro switches. Background Technology

[0002] A micro switch, as the name suggests, is a switch that uses very little force. It is a switch in which external mechanical force acts on an actuating spring through a transmission element, causing the fixed contact at its end to quickly connect or disconnect with the moving contact. A micro switch has a small contact interval and a quick-acting mechanism. The contact mechanism, which performs the switching action with a specified stroke and force, is covered by a housing, has an external actuator, and is relatively small in size.

[0003] In the existing technology, in order to improve the stability of the micro switch during the processing, clamps are used to squeeze both sides of the micro switch to fix it and improve processing stability.

[0004] The existing technology still has some shortcomings. Simply pressing the two sides of the micro switch with two clamps makes it impossible for the micro switch to be accurately centered on the top of the worktable, which can easily cause the micro switch to deviate during the processing and thus affect the processing accuracy. To address this, we propose a tooling fixture for micro switch processing. Utility Model Content

[0005] The purpose of this invention is to provide a tooling fixture for processing micro switches, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tooling fixture for processing micro switches, including a mounting plate;

[0007] Two grooves are formed inside the mounting plate;

[0008] The micro switch body is slidably connected to the top of the mounting plate;

[0009] And a clamping assembly for fixing the micro switch body, the clamping assembly including a rotating rod rotatably connected to the center of the bottom of the mounting plate via a bearing, a rotating block fixedly connected to the outer wall of the middle part of the rotating rod, a U-shaped bottom block rotatably connected to the outer wall of the bottom of the rotating rod via a bearing, the top of the U-shaped bottom block being fixedly connected to the bottom of the mounting plate, a vertical plate fixedly connected to the center of the bottom of the U-shaped bottom block, an electric push rod fixedly connected to the side wall of the vertical plate, a displacement plate fixedly connected to the output end of the electric push rod, a displacement frame fixedly connected to the top of the displacement plate, and a top outer wall of the displacement frame slidingly connected to the inner wall of the slide groove. The inner wall of the frame is movably connected to a connecting plate via a hinge. The other end of the connecting plate is movably connected to the inner wall of the rotating block via a hinge. A clamping plate is fixedly connected to the top of the displacement frame. By setting up a clamping assembly, when one of the connecting plates rotates, it will pull the rotating block to rotate. When the rotating block rotates, it will pull the other connecting plate to rotate and pull the other displacement frame to move. When the two displacement frames are relatively close, the side walls of the two clamping plates will press against the outer wall of the micro switch body, thereby achieving clamping and fixing of the micro switch body to improve the stability during the processing of the micro switch body.

[0010] Preferably, there are two displacement frames, which are symmetrically distributed along the center plane of the mounting plate, and the top outer walls of the two displacement frames are respectively adapted to the inner walls of the two slides.

[0011] Preferably, the top of the mounting plate is further provided with a positioning component. The positioning component includes a U-shaped frame fixedly connected to the top of the front side of the mounting plate. The inner wall of the U-shaped frame is rotatably connected to a bidirectional threaded rod via a bearing. The other end of the bidirectional threaded rod movably penetrates the interior of the front side of the U-shaped frame. An adjusting block is fixedly connected to the outer wall of the other end of the bidirectional threaded rod. Two sleeve blocks are symmetrically threaded to the outer wall of the bidirectional threaded rod. The tops of the two sleeve blocks are slidably connected to the top of the inner wall of the U-shaped frame. An L-shaped plate is fixedly connected to the bottom of the sleeve blocks. The bottom of the L-shaped plate is slidably connected to the top of the mounting plate. A positioning block is fixedly connected to the other end of the L-shaped plate. The side wall of the positioning block is slidably connected to the outer wall of the micro switch body. The positioning assembly is used to initially position the microswitch body after the operator places it on top of the mounting plate. This initial positioning ensures the microswitch body is centered on the mounting plate. The operator rotates the adjusting block, causing the bidirectional threaded rod to rotate. During this rotation, the two socket blocks move closer together. As the two socket blocks move, they move the two L-shaped plates and push the two positioning blocks until the sidewalls of the two positioning blocks press against the front and rear sides of the microswitch body. This initial positioning of the microswitch body, placing it at the top center of the mounting plate, facilitates further processing by the operator.

[0012] Preferably, the bottom of the mounting plate is fixedly connected with four support legs. The four support legs are equidistantly fixedly connected to the bottom of the four corners of the mounting plate. The four support legs at the bottom of the mounting plate can provide stable support for the mounting plate.

[0013] Preferably, there are two connecting plates, and the two connecting plates are respectively movably connected to the inner walls of the two displacement frames.

[0014] Preferably, there are two positioning blocks, which are located on the front and rear sides of the micro switch body.

[0015] This invention provides a tooling fixture for machining micro switches. This tooling fixture for machining micro switches has the following advantages:

[0016] (1) The tooling fixture for processing the micro switch, by setting up a clamping component, ensures the stability of the micro switch body during processing. First, the micro switch body needs to be clamped and fixed. The operator places the micro switch body at the top center of the mounting plate, and then closes the electric push rod, causing the output end of the electric push rod to retract. When the output end of the electric push rod retracts, it will pull the displacement plate to move. When the displacement plate moves, it will drive one of the displacement frames to move along the inner wall of the slide. During the movement, the clamping plates will move. When the displacement frame moves, the hinge will squeeze one of the connecting plates to rotate. When one of the connecting plates rotates, it will pull the rotating block to rotate. When the rotating block rotates, it will pull the other connecting plate to rotate and pull the other displacement frame to move. When the two displacement frames are relatively close, the side walls of the two clamping plates will squeeze the outer wall of the micro switch body, thereby clamping and fixing the micro switch body to improve the stability during the processing of the micro switch body.

[0017] (2) The tooling fixture for processing the micro switch, by setting a positioning component, when the operator places the micro switch body on the top of the mounting plate, the micro switch body first needs to be initially positioned so that the micro switch body is in the center position of the mounting plate. The operator rotates the adjusting block to make the bidirectional threaded rod rotate. During the rotation of the bidirectional threaded rod, the two socket blocks will be brought closer to each other. When the two socket blocks move, they will drive the two L-shaped plates to move and push the two positioning blocks to move until the side walls of the two positioning blocks press against the front and rear sides of the micro switch body, thereby achieving the initial positioning of the micro switch body and making the micro switch body in the top center position of the mounting plate, which makes it convenient for the operator to process the micro switch body.

[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, this utility model has the following two specific embodiments.

[0025] Example 1

[0026] A tooling fixture for machining micro switches includes a mounting plate 1;

[0027] Two grooves 3 are formed inside the mounting plate 1;

[0028] The micro switch body 5 is slidably connected to the top of the mounting plate 1;

[0029] And a clamping assembly 41 for fixing the micro switch body 5. The clamping assembly 41 includes a rotating rod 411 rotatably connected to the bottom center of the mounting plate 1 via a bearing. A rotating block 412 is fixedly connected to the outer wall of the middle part of the rotating rod 411. A U-shaped bottom block 413 is rotatably connected to the bottom outer wall of the rotating rod 411 via a bearing. The top of the U-shaped bottom block 413 is fixedly connected to the bottom of the mounting plate 1. A vertical plate 414 is fixedly connected to the bottom center of the U-shaped bottom block 413. An electric push rod 415 is fixedly connected to the side wall of the vertical plate 414. A displacement plate 416 is fixedly connected to the output end of the electric push rod 415. A displacement frame 417 is fixedly connected to the top of the displacement plate 416. The top outer wall of the displacement frame 417 is slidably connected to the inner wall of the slide groove 3. A connecting plate 418 is movably connected to the inner wall of the displacement frame 417 via a hinge. The other end of the connecting plate 418 is movably connected to the inner wall of the rotating block 412 via a hinge. A clamping plate 419 is fixedly connected to the top of the displacement frame 417.

[0030] By setting the clamping assembly 41, in order to ensure the stability of the micro switch body 5 during processing, the micro switch body 5 first needs to be clamped and fixed. The operator places the micro switch body 5 at the top center of the mounting plate 1, and then closes the electric push rod 415, causing the output end of the electric push rod 415 to retract. When the output end of the electric push rod 415 retracts, it will pull the displacement plate 416 to move. When the displacement plate 416 moves, it will drive one of the displacement frames 417 to move along the inner wall of the slide groove 3. When the displacement frame 417 moves, it will drive... When the clamping plate 419 moves and the displacement frame 417 moves, the hinge will press one of the connecting plates 418 to rotate. When one of the connecting plates 418 rotates, it will pull the rotating block 412 to rotate. When the rotating block 412 rotates, it will pull the other connecting plate 418 to rotate and pull the other displacement frame 417 to move. When the two displacement frames 417 are relatively close, the side walls of the two clamping plates 419 will press against the outer wall of the micro switch body 5, thereby clamping and fixing the micro switch body 5 to improve the stability of the micro switch body 5 during processing.

[0031] There are two displacement frames 417. The two displacement frames 417 are symmetrically distributed along the center plane of the mounting plate 1. The top outer wall of the two displacement frames 417 is adapted to the inner wall of the two slide grooves 3 respectively.

[0032] The bottom of the mounting plate 1 is fixedly connected with four support legs 2. The four support legs 2 are fixedly connected at equal intervals at the bottom of the four corners of the mounting plate 1. The four support legs 2 at the bottom of the mounting plate 1 can provide stable support for the mounting plate 1.

[0033] There are two connecting plates 418, and the two connecting plates 418 are respectively movably connected to the inner walls of the two displacement frames 417.

[0034] Example 2

[0035] The difference from Embodiment 1 is that this embodiment discloses a positioning component, such as... Figure 4 As shown:

[0036] The top of the mounting plate 1 is also provided with a positioning component 42. The positioning component 42 includes a U-shaped frame 421 fixedly connected to the top of the front of the mounting plate 1. The inner wall of the U-shaped frame 421 is rotatably connected to a bidirectional threaded rod 422 via a bearing. The other end of the bidirectional threaded rod 422 moves through the interior of the front of the U-shaped frame 421. An adjusting block 423 is fixedly connected to the outer wall of the other end of the bidirectional threaded rod 422. Two sleeve blocks 424 are symmetrically threaded to the outer wall of the bidirectional threaded rod 422. The top of the two sleeve blocks 424 is slidably connected to the top of the inner wall of the U-shaped frame 421. An L-shaped plate 425 is fixedly connected to the bottom of the sleeve blocks 424. The bottom of the L-shaped plate 425 is slidably connected to the top of the mounting plate 1. A positioning block 426 is fixedly connected to the other end of the L-shaped plate 425. The side wall of the positioning block 426 is slidably connected to the outer wall of the micro switch body 5.

[0037] By setting the positioning component 42, when the operator places the micro switch body 5 on the top of the mounting plate 1, the micro switch body 5 needs to be initially positioned so that it is in the center of the mounting plate 1. The operator rotates the adjusting block 423 to make the bidirectional threaded rod 422 rotate. During the rotation of the bidirectional threaded rod 422, the two socket blocks 424 will move closer to each other. When the two socket blocks 424 move, they will drive the two L-shaped plates 425 to move and push the two positioning blocks 426 to move until the side walls of the two positioning blocks 426 press against the front and rear sides of the micro switch body 5, thereby achieving the initial positioning of the micro switch body 5 and placing it in the top center of the mounting plate 1, which makes it easier for the operator to process the micro switch body 5.

[0038] There are two positioning blocks 426, which are located on the front and rear sides of the micro switch body 5.

[0039] Working principle: During the processing of the micro switch body 5, in order to ensure the stability of the micro switch body 5 during processing, it is first necessary to clamp and fix the micro switch body 5. The operator places the micro switch body 5 at the top center of the mounting plate 1, and then closes the electric push rod 415, causing the output end of the electric push rod 415 to retract. When the output end of the electric push rod 415 retracts, it will pull the displacement plate 416 to move. When the displacement plate 416 moves, it will drive one of the displacement frames 417 to move along the inner wall of the slide groove 3. When the displacement frame 417 moves, it will drive the clamping plate 4. When the displacement frame 417 moves, the hinge will press one of the connecting plates 418 to rotate. When one of the connecting plates 418 rotates, it will pull the rotating block 412 to rotate. When the rotating block 412 rotates, it will pull the other connecting plate 418 to rotate and pull the other displacement frame 417 to move. When the two displacement frames 417 are relatively close, the side walls of the two clamping plates 419 will press against the outer wall of the micro switch body 5, thereby clamping and fixing the micro switch body 5 to improve the stability of the micro switch body 5 during processing.

[0040] After the operator places the micro switch body 5 on top of the mounting plate 1, the micro switch body 5 needs to be initially positioned so that it is centered on the mounting plate 1. The operator rotates the adjusting block 423 to cause the bidirectional threaded rod 422 to rotate. During the rotation of the bidirectional threaded rod 422, the two socket blocks 424 will move closer to each other. As the two socket blocks 424 move, they will drive the two L-shaped plates 425 to move and push the two positioning blocks 426 to move until the side walls of the two positioning blocks 426 press against the front and rear sides of the micro switch body 5. This achieves the initial positioning of the micro switch body 5, placing it at the top center of the mounting plate 1, which facilitates the operator's processing of the micro switch body 5.

[0041] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification of this utility model can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to this application.
