[0033] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0034] It is understandable that, referring to Figures 1 to 7The leaf spring seat positioning fixture of the utility model includes a base 100, a side push assembly 300 and a driving assembly 400. Two groups of positioning assemblies 200 are arranged on the base 100. The positioning assembly 200 includes a support block 210 and two positioning shafts 220. The support block 210 is used to support the leaf spring seat 500, and the positioning shaft 220 is used to snap into the slot 510 of the leaf spring seat 500. The side push assembly 300 is arranged between the two groups of positioning assemblies 200. The two positioning shafts 220 of each group of positioning assemblies 200 are arranged on the support block 210. On the side away from the side push assembly 300, the side push assembly 300 includes a first slider 310 and two second sliders 320. The two second sliders 320 are both slidably connected to the base 100, and the two second sliders 320 are respectively slidably connected to the opposite sides of the first slider 310. The first slider 310 and the second slider 320 are matched with each other on the inclined surfaces. The first slider 310 can move up and down to drive the two second sliders 320 to move synchronously towards or away from each other; the driving assembly 400 is used to drive the first slider 310 to move up and down.

[0035] The two leaf spring seats 500 are respectively placed on the support blocks 210 of the two sets of positioning assemblies 200, and the driving assembly 400 drives the first slider 310 to move up and down, so as to drive the two second sliders 320 to move synchronously toward or away from each other. When the two second sliders 320 move synchronously away from each other, the two second sliders 320 can respectively abut the two leaf spring seats 500 and push the two leaf spring seats 500 to move away from each other until the two positioning shafts 220 on the side of the leaf spring seat 500 away from the second slider 320 are inserted into the two slots 510 on the same side of the leaf spring seat 500. In the embodiment, the leaf spring seat 500 is positioned, and the second slider 320 on one side of the leaf spring seat 500 and the positioning shaft 220 on the other side of the leaf spring seat 500 cooperate to clamp and fix the leaf spring seat 500, so that the two leaf spring seats 500 can be clamped and fixed at the same time, thereby improving production efficiency. When the two second sliders 320 move synchronously toward each other, the second slider 320 is separated from the leaf spring seat 500, thereby releasing the workpiece and facilitating the removal of the leaf spring seat 500. In addition, the clamping and loosening of the workpiece are driven by the driving assembly 400, which can reduce the labor intensity and improve the efficiency of clamping and removing parts.

[0036] It should be noted that the inclined surface cooperation between the first slider 310 and the second slider 320 means that both side walls of the first slider 310 abutting against the second slider 320 are provided with inclined surfaces, and the wall of the second slider 320 abutting against the first slider 310 is also provided with an inclined surface. The inclined surface of the first slider 310 can be slidably cooperated with the inclined surface of the second slider 320, so that when the first slider 310 moves, it can drive the two second sliders 320 to move away from each other synchronously.

[0037] The first slider 310 and the second slider 320 can be connected by a spring return structure, an embedded sliding connection structure, or a connecting rod mechanism, so that when the first slider 310 moves, it can drive the two second sliders 320 to move synchronously toward each other.

[0038] The driving component 400 can be an oil cylinder, an air cylinder 410 , an electric push rod or a linear slide module, etc., which can drive the first slider 310 to move up and down.

[0039] It is understandable that, referring to 5 to Figure 7 The first slider 310 is provided with a slide groove 311, which is arranged along the inclined direction of the inclined surface of the first slider 310, and the second slider 320 is provided with a clamping portion 321, which is embedded in the slide groove 311. By arranging the slide groove 311 along the inclined direction of the inclined surface of the first slider 310, and providing the second slider 320 with a clamping portion 321, and the clamping portion 321 is embedded in the slide groove 311, the clamping portion 321 can be limited to slide in the slide groove 311, so that when the first slider 310 moves up or down, the clamping portion 321 can abut against the wall surface of the slide groove 311, so as to drive the two second sliders 320 to move synchronously toward or away from each other, thereby simplifying the connection structure between the first slider 310 and the second slider 320, and improving the sliding stability of the second slider 320.

[0040] It should be noted that the slide groove 311 can be set on the inclined surface of the first slider 310, and the slide groove 311 is set as a dovetail groove; it can also be set on the wall surfaces on both sides of the inclined surface of the first slider 310, and can be arranged on only one side of the wall surface, or can be arranged on both side walls respectively, so that the clamping portion 321 can be limited to slide in the slide groove 311, so that when the first slider 310 moves up and down, it can drive the two second sliders 320 to move synchronously closer to or away from each other.

[0041] Specifically, refer to Figures 5 to 7 The wall surfaces on both sides of the inclined surface of the first slider 310 are provided with sliding grooves 311. By providing the sliding grooves 311 on both sides of the inclined surface of the first slider 310, the clamping parts 321 are respectively embedded in the sliding grooves 311 on both sides of the first slider 310, which can reduce the shaking of the second slider 320 during the sliding process, and the clamping parts 321 can respectively abut against the wall surfaces of the sliding grooves 311 on both sides, so that the forces on both sides of the second slider 320 are balanced, thereby improving the sliding stability of the second slider 320.

[0042] It is understandable that, referring to Figures 5 to 7The wall surface of the second slider 320 abutting against the first slider 310 is provided with a first guide groove 322, and the first slider 310 is provided with a first protrusion 312, and the first protrusion 312 is slidably connected to the first guide groove 322. The first protrusion 312 is slidably connected to the first guide groove 322, so that the first protrusion 312 can slide in the first guide groove 322, thereby guiding the sliding of the second slider 320 relative to the first slider 310, reducing the shaking of the second slider 320 during the sliding process, and thus improving the sliding stability of the second slider 320.

[0043] It is understandable that, referring to Figures 5 to 7 The base 100 is provided with a slider support 330, the slider support 330 is provided with a second protrusion 331, the second slider 320 is provided with a second guide groove 323, and the second protrusion 331 is slidably connected to the second guide groove 323. The second protrusion 331 is slidably connected to the second guide groove 323, so that the second protrusion 331 can slide in the second guide groove 323, thereby guiding the sliding of the second slider 320 relative to the slider support 330, reducing the shaking of the second slider 320 during the sliding process, and thus improving the sliding stability of the second slider 320.

[0044] It should be noted that the slider support 330 can be detachably connected to the base 100, which makes it easy to disassemble and replace the slider support 330, and when the second protrusion 331 is worn and needs to be replaced, it is not necessary to replace it together with the base 100, thereby reducing the maintenance cost of the leaf spring seat positioning fixture.

[0045] Specifically, refer to Figures 5 to 7 The bottom of the first slider 310 is provided with a positioning groove 313, and the second protrusion 331 can be embedded in the positioning groove 313 to position the first slider 310. The positioning groove 313 is provided at the bottom of the first slider 310, so that when the first slider 310 moves downward to the slider support 330, the second protrusion 331 can be embedded in the positioning groove 313, thereby positioning the first slider 310, and the direction and position of the first slider 310 can be conveniently positioned, thereby improving the assembly accuracy of the first slider 310.

[0046] It is understandable that, referring to Figures 5 to 7The driving assembly 400 includes a cylinder 410, a pull rod 420 and a compression spring 430. The cylinder 410 is set on the base 100. One end of the pull rod 420 is fixedly connected to the movable end of the cylinder 410. The other end of the pull rod 420 can abut against the top of the first slider 310 to drive the first slider 310 to move downward. One end of the compression spring 430 is fixedly connected to the movable end of the cylinder 410, and the other end of the compression spring 430 is fixedly connected to the bottom of the first slider 310. One end of the pull rod 420 is fixedly connected to the movable end of the cylinder 410, so that the pull rod 420 can move downward together with the movable end of the cylinder 410, and the other end of the pull rod 420 abuts against the top of the first slider 310 to drive the first slider 310 to move downward. At this time, the compression spring 430 is in a compressed state. Since one end of the compression spring 430 is fixedly connected to the movable end of the cylinder 410, and the other end of the compression spring 430 is fixedly connected to the bottom of the first slider 310, the elastic force of the compression spring 430 is used to make the first slider 310 abut against one end of the pull rod 420, and as the movable end of the cylinder 410 rises, the compression spring 430 can abut and support the first slider 310 to move upward. The overall lifting drive structure is simple and easy to assemble. At the same time, the buffering effect of the compression spring 430 is used to reduce shock, which can improve the stability of the lifting movement of the first slider 310.

[0047] It should be noted that baffles 110 may be provided on both sides of the base 100, and the cylinder 410 is located between the two baffles 110. The baffles 110 are used to protect the cylinder 410, so as to reduce the metal debris splashing to the cylinder 410 during the workpiece processing and damage the cylinder 410 and the air pipe, thereby extending the service life of the cylinder 410 and the air pipe, and improving the appearance of the leaf spring seat positioning fixture.

[0048] Specifically, refer to Figures 5 to 7 The first slider 310 is provided with a guide hole 314, and the pull rod 420 is inserted in the guide hole 314, so that the first slider 310 can move along the axial direction of the pull rod 420. The first slider 310 is provided with a guide hole 314, and the pull rod 420 is inserted in the guide hole 314, so that the first slider 310 can move along the axial direction of the pull rod 420, thereby guiding the movement of the first slider 310, reducing the shaking and position deviation of the first slider 310, and further improving the stability of the lifting movement of the first slider 310.

[0049] Specifically, refer to Figures 5 to 7, the shape of the first slider 310 is a trapezoid with a narrow top and a wide bottom, and the shape of the second slider 320 is a trapezoid with a wide top and a narrow bottom. Since the shape of the first slider 310 is a trapezoid with a narrow top and a wide bottom, and the shape of the second slider 320 is a trapezoid with a wide top and a narrow bottom, when the driving assembly 400 drives the first slider 310 to move downward, the two second sliders 320 move away from each other synchronously, so that the second sliders 320 abut against one side of the leaf spring seat 500, and cooperate with the positioning shaft 220 to clamp and fix the leaf spring seat 500. At this time, the contact area between the first slider 310 and the second slider 320 reaches the maximum, which can balance the force on the contact surface, reduce the deformation or wear of the first slider 310 and the second slider 320 caused by local stress, thereby extending the service life of the first slider 310 and the second slider 320, and can provide a stable side thrust to clamp the leaf spring seat 500, thereby improving the clamping stability of the leaf spring seat positioning fixture.

[0050] It should be noted that the first slider 310 may also be configured as a trapezoid that is wide at the top and narrow at the bottom, while the second slider 320 may be configured as a trapezoid that is narrow at the top and wide at the bottom, so that the first slider 310 and the second slider 320 can be matched with each other on the inclined surfaces.

[0051] It is understandable that, referring to Figures 5 to 7 The positioning shaft 220 is connected to the base 100 through the fastener 230. Since the positioning shaft 220 is connected to the base 100 through the fastener 230, the positioning shaft 220 of the corresponding size can be conveniently replaced by rotating the fastener 230 according to the size of the slot 510 of the leaf spring seat 500, so as to accurately locate the position of the leaf spring seat 500, thereby improving the convenience and versatility of the leaf spring seat positioning fixture.

[0052] It should be noted that the fastener 230 may be a bolt or a screw, etc., as long as it can connect the positioning shaft 220 to the base 100, and is not limited here.

[0053] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
