The guide columns are slidably connected to the inner walls of turntables a and b. A rotating ring is rotatably connected to the upper part of turntable b. Multiple sets of sliding teeth are fixedly connected around the outer side of the rotating ring. The contact portion slides on the outer side of the sliding teeth.

[0006] As a further description of the above technical solution: The drive assembly includes an incomplete worm gear, which is fixedly connected to the upper part of the rotating ring. Two sets of bearing seats are fixedly connected to the upper part of the turntable a near the right side of the incomplete worm gear. A worm is fixedly connected to the inner wall of the bearing seat, and the worm meshes with the incomplete worm gear.

[0007] As a further description of the above technical solution: The front side of the worm gear is configured as a regular hexagon.

[0008] As a further description of the above technical solution: The positioning component includes a housing, a sliding member is movably connected through the inner wall of the housing, a baffle is fixedly connected to the outer side of the sliding member, the baffle is elastically connected to the housing by a compression spring, an abutment plate a is fixedly connected to the front side of the sliding member, an abutment plate b is fixedly connected to the rear side of the worm gear, the abutment plate a and the abutment plate b are in contact with each other, a limiting groove is formed in the upper part of the housing, and the sliding member slides on the inner wall of the limiting groove.

[0010] As a further description of the above technical solution: The support base is configured in an arc shape, and multiple sets of the support base are provided, with adjacent sets of the support base arranged symmetrically.

[0011] As a further description of the above technical solution: The contact part is set as an arc surface on the side near the sliding tooth, and the multiple sets of connecting rods are evenly distributed radially around the center of turntable a.

[0012] As a further description of the above technical solution: The outer wall of the turntable a has a scale line near the movable groove, and a pointer is fixedly connected to the upper part of the support base near the scale line.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the drive component drives the rotating ring and sliding teeth to rotate through the meshing of a worm gear and a partially meshed worm wheel. The sliding teeth cooperate with the arc surface of the contact part to push the connecting rod to move radially.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 - Figure 3This utility model provides an embodiment of an assembly fixture for the production of a press pump with precise positioning capabilities, comprising a turntable a1 and a turntable b2, providing a carrier for an adjustment component 4 and a drive component 5. The turntable b2 is fixedly mounted on the lower part of the turntable a1 by multiple sets of bolts. An adjustment component 4 is provided between the turntable a1 and the turntable b2 to realize the opening, closing and positioning of the support base 49. Multiple sets of movable grooves 3 are provided around the edges of the turntable a1 and the turntable b2 to provide clearance for the movement of the support base 49 and ensure the adjustment stroke. A drive component 5 is provided between the adjustment component 4 and the turntable a1 to provide power to the adjustment component 4 and realize precise transmission. A positioning component 6 is provided on the upper part of the turntable a1 near the rear side of the drive component 5 to lock the position of the drive component 5 and prevent displacement after adjustment.

[0019] Reference Figure 3 , Figure 5 and Figure 6 The adjusting component 4 includes multiple sets of connecting rods 41, which transmit the driving force of the contact part 42 and drive the moving plate 44 to move synchronously. The multiple sets of connecting rods 41 slide on the inner walls of turntable a1 and turntable b2. The contact part 42 is fixedly connected to the connecting rod 41 near the center of turntable a1 and cooperates with the sliding tooth 412 to convert the rotational motion of the ring 411 into the radial movement of the connecting rod 41. The contact part 42 is elastically connected to turntable a1 and turntable b2 through a return spring 43 to provide a return force for the connecting rod 41. After adjustment, the component is driven back to the initial position. The elasticity of the return spring 43 can ensure the stability of the contact part 42 and the connecting rod 41. The end of the connecting rod 41 away from the contact part 42 is fixedly connected to the moving plate 44. The guide member 46 is driven to move through the guide groove 45 to realize the opening and closing of the support seat 49. Two sets of guide grooves 45 are symmetrically inclined on the outer side of the moving plate 44 to provide a sliding track for the guide member 46 and convert the radial movement of the moving plate 44 into the radial movement of the support seat 49. The pump moves towards the clamping mechanism. Guide members 46 are slidably connected to the inner walls of both sets of guide grooves 45, connecting the moving plate 44 and the support base 49 to transmit driving force. A sliding groove 47 is formed through the inner wall of the guide member 46. The end of the guide member 46 away from the moving plate 44 is fixedly connected to the support base 49, directly supporting the pump. Its arc-shaped design adapts to the contour of the pump housing. Multiple sets of support columns 410 are fixedly connected to the upper part of the support base 49. These columns are inserted into the bottom of the pump, reserving space for assembly operations. A guide post 48 is fixedly connected to the outside of the support base 49 to limit the movement trajectory of the support base 49 and prevent tilting and jamming. The guide post 48 is slidably connected to the inner wall of the turntable a1 and the turntable b2. The upper part of the turntable b2 is rotatably connected to the ring 411, which drives the sliding teeth 412 to rotate synchronously and transmits the power of the drive component 5. Multiple sets of sliding teeth 412 are fixedly connected around the outside of the ring 411 and cooperate with the contact part 42. The contact part 42 is pushed to move by the tooth surface and slides on the outside of the sliding teeth 412.

[0020] Reference Figure 3and Figure 4 The drive assembly 5 includes an incomplete worm gear 51 that meshes with the worm 53, transmitting the rotational motion of the worm 53 to the rotating ring 411. The incomplete worm gear 51 is fixedly connected to the upper part of the rotating ring 411. Two sets of bearing seats 52 are fixedly connected to the upper part of the turntable a1 near the right side of the incomplete worm gear 51, supporting the worm 53 and ensuring its stable rotation. The worm 53 is fixedly connected to the inner wall of the bearing seat 52, serving as a power input component, driving the incomplete worm gear 51 through meshing transmission. The worm 53 meshes with the incomplete worm gear 51. The front side of the worm 53 is designed in a regular hexagonal shape to facilitate the use of tools such as wrenches, enabling quick manual adjustment.

[0021] Reference Figure 3 and Figure 4 The positioning component 6 includes a housing 61, which provides installation protection for the internal components of the positioning component 6. A sliding member 62 is movably connected through the inner wall of the housing 61, which drives the abutment plate a65 to move, thereby achieving positioning and unlocking. A baffle 63 is fixedly connected to the outer side of the sliding member 62, which bears the elastic force of the compression spring 64 and transmits it to the sliding member 62. The baffle 63 and the housing 61 are elastically connected through the compression spring 64, providing a continuous pressing force to the abutment plate a65 to ensure positioning stability. The front side of the sliding member 62 is fixedly... A fixed connection is provided with an abutment plate a65. The outer side of the abutment plate a65 is made of rubber and fits against the abutment plate b66. The worm gear 53 is locked by friction. The rear side of the worm gear 53 is fixedly connected with the abutment plate b66, which cooperates with the abutment plate a65 to form a positioning friction surface. The abutment plate a65 and the abutment plate b66 fit against each other. A limit groove 67 is provided on the upper part of the outer shell 61 to position the sliding member 62, thereby facilitating the rotation of the worm gear 53. The sliding member 62 slides on the inner wall of the limit groove 67.

[0022] Reference Figure 1 , Figure 4 and Figure 7 The sliding member 62 is T-shaped for easy operation, and the limiting groove 67 is L-shaped to limit and position the stroke of the sliding member 62, ensuring precise operation. The support base 49 is arc-shaped to fit the contour of the pump housing. Multiple sets of support bases 49 are provided, with adjacent sets of support bases 49 symmetrically arranged to achieve multi-directional centering clamping and ensure coaxial positioning. The side of the contact part 42 near the sliding tooth 412 is arc-shaped to reduce contact friction with the sliding tooth 412 and improve transmission smoothness. Multiple sets of connecting rods 41 are evenly distributed radially around the center of the turntable a1 to ensure synchronous adjustment of the support base 49 and achieve centering positioning. The outer wall of the turntable a1 is provided with a scale line 7 near the movable groove 3 to provide a precise adjustment reference. A pointer 8 is fixedly connected to the upper part of the support base 49 near the scale line 7, pointing to the scale line 7, allowing for intuitive reading of the adjustment distance and achieving precise positioning.

[0023] Working principle: When in use, the worm 53 is rotated, and it meshes with the incomplete worm wheel 51 for transmission. Because the worm wheel and worm have the characteristics of large reduction ratio and smooth transmission, the rapid rotation of the worm 53 can be converted into the slow and uniform rotation of the incomplete worm wheel 51. The incomplete worm wheel 51 is fixedly connected to the rotating ring 411, which in turn drives the rotating ring 411 to rotate synchronously. The multiple sets of sliding teeth 412 on the outer side of the rotating ring 411 rotate together with the rotating ring 411, completing the transmission of power from input to adjustment component 4.

[0024] When the sliding tooth 412 rotates, its tooth surface comes into contact with the arc surface of the contact part 42 and generates a thrust. The contact part 42 is driven by the thrust to move the connecting rod 41 radially along the inner wall of the turntable a1 and turntable b2. At this time, the return spring 43 is compressed and stores elastic potential energy.

[0025] The movable plate 44 moves radially synchronously with the connecting rod 41. The inclined guide groove 45 on the outer side of the movable plate 44 slides with the guide member 46, converting the radial displacement of the movable plate 44 into the relative movement of the guide member 46, thereby driving the support base 49 to contract or expand synchronously.

[0026] The scale line 7 on the outer wall of the turntable a1 works in conjunction with the pointer 8 on the support base 49. When the support base 49 moves, the pointer 8 points to the corresponding scale in sync. The operator can intuitively read the adjustment distance, achieve precise positioning, and adapt to press pumps of different diameters.

[0027] The compression spring 64 in the positioning assembly 6 pushes the baffle 63 and the slider 62 forward, so that the abutment plate a65 on the front side of the slider 62 and the abutment plate b66 on the rear side of the worm 53 are tightly fitted. The abutment plate a65 is made of rubber and locks the rotation position of the worm 53 through friction, thereby fixing the state of the rotating ring 411 and the support seat 49, preventing the support seat 49 from shifting due to vibration during assembly, and ensuring positioning stability.

[0028] When unlocking and adjustment are required, manually pull the T-shaped slider 62 to make it slide along the L-shaped limiting groove 67. The baffle 63 compresses the compression spring 64, and the abutment plate a65 separates from the abutment plate b66. The worm gear 53 can then be rotated again for adjustment.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
