Description

Technical Field

[0001] This solution belongs to the field of fixture technology, specifically involving a compact machining fixture for thermostat housings. Background Technology

[0002] Utility model patent CN217371518U discloses a compact machining fixture for thermostat housings, comprising a base plate, an oil passage disposed inside the base plate, an airtightness detection mechanism disposed above the base plate and connected to the oil passage, and multiple sets of process fixtures disposed above the base plate corresponding to multiple processing steps. Each process fixture includes a clamping mechanism disposed on the base plate, multiple sets of positioning pin assemblies adapted to the parts to be processed, and auxiliary support blocks. The clamping mechanism, positioning pin assemblies, and auxiliary support blocks are connected to the oil passage for hydraulic control of the clamping mechanism, positioning pin assemblies, and auxiliary support blocks. The bottom of the base plate is provided with positioning pins or positioning holes for positioning the base plate during installation. This utility model allows for the arrangement of multiple independent fixtures on a single machine, enabling batch processing, reducing equipment investment, and controlling processing costs.

[0003] However, the device has certain shortcomings in use. It is not easy to adjust and clamp the housing in any position. At the same time, the fixture as a whole is not convenient to disassemble and assemble on the processing equipment. Utility Model Content

[0004] The purpose of this solution is to provide a compact machining fixture for a thermostat housing, in order to solve the problems that the device is not convenient to adjust and clamp the housing in any position, and that the fixture as a whole is not convenient to assemble and disassemble on the machining equipment.

[0005] To achieve the above objectives, this solution provides a compact machining fixture for thermostat housings, including a bracket, an installation mechanism on the bracket, a support plate on the installation mechanism, a cylinder fixedly mounted on the surface of the support plate, a cylinder rod passing through the support plate and slidably connected to the support plate, a clamping mechanism on the cylinder rod, and a clamping block on the clamping mechanism.

[0006] The principle of this solution is as follows: Manually moving the lever causes the insertion rod to move, allowing it to slide within the bracket. The moving rod compresses the spring, bringing the bracket into contact with the processing equipment. This allows the insertion block on the equipment to be inserted into the bracket. Releasing the lever then returns the spring to its original position, allowing the insertion rod to enter the insertion block and limit its movement. The lever's movement allows the insertion rod to slide within the bracket, and the spring's elasticity facilitates its return to its original position. This makes it easier for the insertion rod to engage and disengage with the insertion block, thus facilitating bracket assembly and disassembly. The housing is then placed on the bracket, and the cylinder is activated. The cylinder drives the compression spring on the guide rail, causing the clamping block to slide along the guide rail. This change in the clamping block's position allows for clamping of any housing, preventing different housing orientations from affecting clamping.

[0007] The technical advantage of this solution is that the lever moves the insertion rod to slide within the bracket, and the spring elasticity makes it easy for the insertion rod to return to its original position. This makes it easier for the insertion rod to engage and disengage with the insertion block that has been inserted into the bracket, thus making the assembly and disassembly of the bracket more convenient.

[0008] The cylinder drives the compression spring to act on the guide rail, and the clamping block slides on the guide rail. This allows the clamping block to change position, making it easier to clamp any housing and avoiding the impact of different housing orientations on the clamping of the housing.

[0009] Furthermore, the installation mechanism includes a plug rod, which is slidably connected inside the bracket. A lever is fixedly connected to the surface of the plug rod, and the lever is slidably connected to the bracket. A spring is installed inside the bracket, with one end of the spring fixedly connected to the plug rod and the other end of the spring fixedly connected to the bracket. The lever moves the plug rod to slide within the bracket, and the spring's elasticity facilitates the plug rod's return to its original position, making it easier to engage and disengage with the insert block inserted into the bracket, thus making the bracket's assembly and disassembly more convenient.

[0010] Furthermore, the bracket has a guide groove inside, which is slidably connected to the lever. The guide groove guides the movement of the lever.

[0011] Furthermore, the clamping mechanism includes a slide cylinder, which is slidably connected to the outer side of the cylinder rod. A guide rail is fixedly connected to the end of the slide cylinder, and the guide rail and clamping block are slidably connected. A compression spring is installed inside the slide cylinder. A guide block is fixedly connected to the lower end of the guide rail, and the guide block is slidably connected to the bracket. A dovetail block is fixedly connected to the lower end of the clamping block, and the dovetail block is slidably connected to the guide rail. The cylinder drives the compression spring to act on the guide rail, causing the clamping block to slide on the guide rail. This allows the position of the clamping block to change, facilitating the clamping of any housing and preventing the different orientations of the housing from affecting the clamping.

[0012] Furthermore, a sliding pin is fixedly connected to the surface of the cylinder rod, and the sliding pin is slidably connected to the slide cylinder. The sliding pin guides the movement of the slide cylinder.

[0013] Furthermore, one end of the compression spring is fixedly connected to the cylinder rod of the cylinder, and the other end of the compression spring is fixedly connected to the guide rail. By setting the compression spring, the guide rail is elastically compressed.

[0014] Furthermore, the guide rail is internally connected with a threaded pin, which is located within a dovetail groove of the guide rail. The pin limits the travel of the clamping block. Attached Figure Description

Detailed Implementation

[0021] The implementation examples are basically as follows Figure 1 As shown, this embodiment provides a compact machining fixture for thermostat housing, including a bracket 1, an installation mechanism 2 on the bracket 1, a support plate 3 on the installation mechanism 2, a cylinder 4 fixedly mounted on the surface of the support plate 3, the cylinder rod of the cylinder 4 passing through the support plate 3 and slidably connected to the support plate 3, a clamping mechanism 5 on the cylinder rod of the cylinder 4, and a clamping block 6 on the clamping mechanism 5.

[0022] like Figure 1 , Figure 2As shown, the installation mechanism 2 includes a plug rod 21. The plug rod 21 is slidably connected inside the bracket 1. A lever 22 is fixedly connected to the surface of the plug rod 21. The lever 22 is slidably connected to the bracket 1. A spring 23 is provided inside the bracket 1. One end of the spring 23 is fixedly connected to the plug rod 21, and the other end of the spring 23 is fixedly connected to the bracket 1. A guide groove 24 is provided inside the bracket 1. The guide groove 24 is slidably connected to the lever 22. By providing the guide groove 24, the movement of the lever 22 is guided. The lever 22 moves the plug rod 21 to slide inside the bracket 1. The elastic action of the spring 23 makes it easy for the plug rod 21 to return to its original position. This makes it easier for the plug rod 21 to engage and disengage with the plug block inserted into the bracket 1, thus making the assembly and disassembly of the bracket 1 more convenient.

[0023] like Figure 1 , Figure 3 , Figure 4 As shown, the clamping mechanism 5 includes a slide cylinder 51. The slide cylinder 51 is slidably connected to the outer side of the cylinder rod of the cylinder 4. A sliding pin 52 is fixedly connected to the surface of the cylinder rod of the cylinder 4. The sliding pin 52 and the slide cylinder 51 are slidably connected. By setting the sliding pin 52, the movement of the slide cylinder 51 is guided. A guide rail 53 is fixedly connected to the end of the slide cylinder 51. The guide rail 53 and the clamping block 6 are slidably connected. A compression spring 54 is set inside the slide cylinder 51. One end of the compression spring 54 is fixedly connected to the cylinder rod of the cylinder 4, and the other end of the compression spring 54 is fixedly connected to the guide rail 53. By setting the compression spring 54, the guide rail 53 is elastically compressed. A guide block 55 is fixedly connected to the lower end of the clamping block 6. The guide block 55 is slidably connected to the bracket 1. A dovetail block 56 is fixedly connected to the lower end of the clamping block 6. The dovetail block 56 is slidably connected to the guide rail 53. A screw pin 57 is threaded inside the guide rail 53. The screw pin 57 is located in the dovetail groove of the guide rail 53. By setting the screw pin 57, the stroke of the clamping block 6 is limited. The cylinder 4 drives the compression spring 54 to act on the guide rail 53 and slide the clamping block 6 on the guide rail 53. Thus, after the position of the clamping block 6 changes, it is convenient to clamp any housing and avoid the different placement orientations of the housing from affecting the clamping of the housing.

[0024] The specific implementation process of this utility model is as follows: Manually move the lever 22, which drives the insertion rod 21 to move, causing the insertion rod 21 to slide within the bracket 1. The movement of the insertion rod 21 compresses the spring 23, and then the bracket 1 moves to contact the processing equipment, allowing the insertion block on the equipment to be inserted into the bracket 1. Then, release the lever 22, and the spring 23 returns to its original position, allowing the insertion rod 21 to enter the insertion block and limit its movement. By moving the insertion rod 21 within the bracket 1 through the lever 22, and by the elastic action of the spring 23, the insertion rod 21 can easily return to its original position, making it easier for the insertion rod 21 to engage and disengage with the insertion block inserted into the bracket 1. This makes the assembly and disassembly of the bracket 1 more convenient. Then, place the housing on the bracket 1 and start the cylinder 4. The cylinder 4 drives the compression spring 54 to act on the guide rail 53, and the clamping block 6 slides on the guide rail 53. This changes the position of the clamping block 6, making it easier to clamp any housing and avoiding the impact of different housing placement orientations on the clamping of the housing.

[0025] The lever 22 moves the insertion rod 21 to slide within the bracket 1, and the spring 23 makes it easy for the insertion rod 21 to return to its original position, thus making it easier for the insertion rod 21 to engage and disengage with the plug block inserted into the bracket 1, thereby making the assembly and disassembly of the bracket 1 more convenient.

[0026] The cylinder 4 drives the compression spring 54 to act on the guide rail 53, and slides the clamping block 6 on the guide rail 53. This allows the clamping block 6 to change position, making it easier to clamp any housing and avoiding the impact of different housing placement orientations on the clamping of the housing.
