Description

Technical Field

[0001] This application relates to the field of valve core press structure technology, and in particular to the structure of a valve core press with a rod. Background Technology

[0002] In the fields of machinery manufacturing and related industrial production, the assembly and processing of parts has always been a crucial link. With the continuous advancement of technology and the increasing scale and precision of industrial production, the requirements for the performance, efficiency, and accuracy of parts assembly equipment are also becoming increasingly stringent.

[0003] In traditional stem valve assembly, manual tools or simple stamping equipment are typically used to compact and position the valve core. Manual tools involve workers using wrenches, pliers, etc., to manually tighten or assemble the stem valve core with other components. While this method is low-cost, it is inefficient and makes it difficult to guarantee assembly precision and consistency. Simple stamping equipment uses cylinders or motors to drive a press head to compact the valve core, but this type of equipment often lacks effective positioning devices, making it prone to valve core positional deviations during assembly. Furthermore, the equipment has poor flexibility and adjustability.

[0004] Existing rod valve core assembly methods have defects. Manual operation tools rely on manpower, which is not only labor-intensive and inefficient, but also makes it difficult to ensure that the assembly quality of each rod valve core meets the same standard due to human factors. Simple stamping equipment, lacking effective positioning devices and flexible adjustment structures, cannot accurately position and compact the valve core during the assembly process, which can easily lead to problems such as inaccurate positioning and inadequate compaction of the assembled rod valve core, affecting the overall performance and quality of the product. Utility Model Content

[0005] To improve the problems of inaccurate assembly and insufficient compaction of the valve core during valve core assembly, resulting in low production efficiency, this application provides a valve core press structure with a rod.

[0006] The stem valve core press structure provided in this application adopts the following technical solution:

[0007] The structure of the rod valve core press includes a base plate, a vertical shaft mounted on the base plate, an upper plate mounted on the end of the vertical shaft away from the base plate, a drive component mounted on the upper plate, and a limiting component mounted on the base plate. The limiting component is rotatably arranged on the base plate. The upper plate and the vertical shaft are detachably connected by fasteners. The output end of the drive component is also connected to an upper pressure head. The drive component is used to drive the upper pressure head to move along its axial direction to achieve compaction. The limiting component is used to position the rod valve core assembly.

[0008] By adopting the above technical solution, the rod valve core is positioned and assembled at the limiting component. The driving component drives the upper pressure head to move along its axial direction, and the upper pressure head is used to compact the rod valve core. The upper plate and the vertical shaft are detachably connected by fasteners, which facilitates the installation, maintenance and disassembly of the equipment. The limiting component is rotatably arranged on the base plate, and its position can be flexibly adjusted to adapt to different rod valve core assembly requirements.

[0009] Optionally, the limiting component includes a limiting screw sleeve installed in a limiting hole on the base plate, a screw sleeve seat installed on the limiting screw sleeve, a joint screw sleeve rotatable on the screw sleeve seat, and a screw sleeve cap installed on the end face of the screw sleeve seat.

[0010] By adopting the above technical solution, when assembling the rod valve core, the limiting component is rotatably arranged on the base plate, which can accurately position the rod valve core. The limiting screw sleeve, screw sleeve seat, joint screw sleeve and screw sleeve cover cooperate with each other to ensure the accurate position of the rod valve core during the assembly process, which facilitates the subsequent driving component to drive the upper pressure head to perform compaction operation.

[0011] Optionally, the drive unit includes a cylinder mounted on the upper plate, a plastic air tube mounted on the cylinder, and a foot-operated air valve switch mounted on the cylinder for controlling the flow of the plastic air tube.

[0012] By adopting the above technical solution, the operator can control the opening and closing of the plastic air tube by stepping on the foot pedal air valve switch, thereby controlling the gas in and out of the cylinder. This allows the output end of the cylinder to drive the upper pressure head to move along its axial direction to achieve the compaction operation, making it convenient and quick to complete the assembly and compaction of the rod valve core.

[0013] Optionally, the fastener includes an adjusting sleeve mounted on the upper plate, the adjusting sleeve being threadedly connected to the vertical shaft, a washer being fitted on the end of the vertical shaft that protrudes from the upper plate, and an external hexagonal nut being coaxially provided on the vertical shaft for locking the upper plate and the vertical shaft.

[0014] By adopting the above technical solution, the upper plate and the vertical shaft can be detachably connected, which makes it easy to adjust and install the position of the upper plate according to actual needs. The shims added increase the installation tightness of the external hexagonal nut and the vertical shaft.

[0015] Optionally, the joint threaded sleeve is further equipped with a reinforcing member, which includes a nut sleeved on the joint threaded sleeve and a support coaxially sleeved on the joint threaded sleeve, the end face of the support being in contact with the nut.

[0016] By adopting the above technical solution, the stability of the joint threaded sleeve is enhanced, thereby improving the reliability of the entire limiting component in assembling and positioning the valve core with rod.

[0017] Optionally, the vertical axis located between the upper plate and the bottom plate is arranged in a triangular shape.

[0018] By adopting the above technical solution, the triangular arrangement of the vertical shaft can improve the overall stability and load-bearing capacity of the rod valve core press structure, make the connection between the upper plate and the bottom plate more stable, and ensure that the entire structure is not easily deformed or shaken when the drive component drives the upper pressure head to compact the rod valve core, thus ensuring the accuracy and reliability of the rod valve core assembly process.

[0019] Optionally, the threaded sleeve seat and the base plate are connected by an internal hexagon screw.

[0020] By adopting the above technical solution, the connection between the screw sleeve seat and the base plate is tighter and more stable, which enhances the overall stability and reliability of the rod valve core press structure.

[0021] Optionally, the base plate has a positioning hole, the axis of which coincides with the axis of the cylinder output end.

[0022] By adopting the above technical solution, the base plate is opened with positioning holes that coincide with the axis of the cylinder output end, which enables better positioning of the rod valve core during assembly, ensures accurate operation of the drive component output end, and improves the assembly accuracy and quality of the rod valve core.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The driving component drives the upper pressure head to move along its axial direction to achieve compaction, which improves the compaction efficiency and quality during the assembly of the rod valve core and avoids the problems of low efficiency and incomplete compaction during manual operation;

[0025] 2. The limiting component is rotatably arranged on the base plate for positioning the valve core assembly with rod, which solves the problem of valve core position deviation caused by the lack of an effective positioning device in existing simple stamping equipment, and improves the assembly accuracy;

[0026] 3. The upper plate and vertical shaft are detachably connected by fasteners, giving the equipment better flexibility and adjustability to meet different assembly needs. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail.

[0035] This application discloses a rod valve core press structure.

[0036] Reference Figure 1 and Figure 2 As shown, the assembly includes a base plate 1, a vertical shaft 2, an upper plate 3, a drive component 4, and a limiting component 5. The vertical shaft 2 is mounted on the base plate 1, the upper plate 3 is mounted on the end of the vertical shaft 2 away from the base plate 1, the drive component 4 is mounted on the upper plate 3, and the limiting component 5 is mounted on the base plate 1 and is rotatably arranged. The upper plate 3 and the vertical shaft 2 are detachably connected by fasteners 7. The output end of the drive component 4 is connected to an upper pressure head 6. The drive component 4 is used to drive the upper pressure head 6 to move along its axial direction to achieve compaction. The limiting component 5 is used to position the rod valve core during assembly, so that the position of the rod valve core can be accurately determined by the limiting component 5 during the assembly of the rod valve core, and the drive component 4 drives the upper pressure head 6 to compact it, which effectively improves the assembly accuracy and efficiency.

[0037] See Figure 4As shown, the limiting component 5 includes a limiting screw sleeve 51, a screw sleeve seat 52, a joint screw sleeve 53, and a screw sleeve cover 54. The limiting screw sleeve 51 is installed in the limiting hole opened in the base plate 1. The limiting screw sleeve 51 and the base plate 1 are made of the same Q235A material and are generally cylindrical, with good wear resistance and strength. The screw sleeve seat 52 is installed on the limiting screw sleeve 51. It is usually a disc-shaped structure with a certain thickness and is made of a similar material to the limiting screw sleeve 51. It is used to support and fix other components. The joint screw sleeve 53 is rotatably installed on the screw sleeve seat 52. It has a specific rotating structure at the connection point to facilitate angle adjustment. Its material is Q235A. The screw sleeve cover 54 is installed on the end face of the screw sleeve seat 52 and serves to seal and protect the internal structure. Its material is Q235A. The limiting screw sleeve 51 is installed in the limiting hole of the base plate 1, providing an installation base for the entire limiting component 5. The screw sleeve seat 52 is fixed on the limiting screw sleeve 51, so that the various components are connected in an orderly manner. The joint screw sleeve 53 is rotatably installed on the screw sleeve seat 52, and the angle can be adjusted according to actual needs to better adapt to different rod valve core assembly situations. The screw sleeve cover 54 is installed on the end face of the screw sleeve seat 52 to prevent dust and other impurities from entering the interior and affecting the rotation and positioning accuracy.

[0038] See Figure 2 As shown, the drive unit 4 includes a cylinder 41, a plastic air hose 42, and a foot-operated air valve switch 43. The cylinder 41 is mounted on the upper plate 3. The cylinder 41 is usually composed of a cylinder body, piston, etc., and its model is SC100X50. The plastic air hose 42 is mounted on the cylinder 41 and is used to transmit gas. It has a certain degree of flexibility and corrosion resistance. Common materials include PVC, and silicone tubing can also be used to improve high temperature resistance and aging resistance. The foot-operated air valve switch 43 is mounted on the cylinder 41 and is used to control the flow of the plastic air hose 42. The operator can conveniently control the action of the cylinder 41 by stepping on it. The cylinder 41 is also equipped with an airflow regulating valve with an interface pipe and an outer diameter of φ8 for regulating airflow. Cylinder 41 is mounted on the upper plate 3 to provide power for the movement of the upper pressure head 6. Plastic air pipe 42 connects cylinder 41 and air supply source to deliver gas to cylinder 41. Foot pedal air valve switch 43 allows operators to control the flow of gas, thereby controlling the movement of cylinder 41 and the upper pressure head 6.

[0039] See Figure 5As shown, fastener 7 includes an adjusting sleeve 71, a washer 72, and an external hexagonal nut 73. The adjusting sleeve 71 is mounted on the upper plate 3 and is threaded to the vertical shaft 2. It is generally cylindrical with threads on the inner wall and is usually made of metal to facilitate threaded engagement with the vertical shaft 2. The washer 72 is fitted onto the end of the vertical shaft 2 that protrudes from the upper plate 3. The external hexagonal nut 73 is coaxially mounted on the vertical shaft 2 and is used to lock the upper plate 3 and the vertical shaft 2. It is hexagonal in shape to facilitate tightening and loosening with tools, and its material is similar to that of the adjusting sleeve 71. The adjusting sleeve 71 is threaded to the vertical shaft 2, allowing adjustment of the position of the upper plate 3 on the vertical shaft 2. The washer 72 is fitted onto the end of the vertical shaft 2 to prevent friction and loosening between the upper plate 3 and the vertical shaft 2. After tightening the external hexagonal nut 73, the upper plate 3 and the vertical shaft 2 are firmly fixed together.

[0040] See Figure 4 As shown, the reinforcing component 8 includes a nut 81 and a support 82. The nut 81, typically hexagonal in shape and made of Q235A material, is fitted onto the joint threaded sleeve 53. The support 82, coaxially fitted onto the joint threaded sleeve 53, has its end face in contact with the nut 81. The support 82 is generally disc-shaped or ring-shaped, made of a similar material to the nut 81, and serves to provide support and reinforcement. The nut 81, fitted onto the joint threaded sleeve 53, provides initial fixation. The support 82, fitted onto the joint threaded sleeve 53 and in contact with the nut 81, further increases the stability of the joint threaded sleeve 53, preventing it from shaking or loosening.

[0041] See Figure 3 As shown, the vertical shaft 2 located between the upper plate 3 and the bottom plate 1 is arranged in a triangular shape. This arrangement makes the entire structure more stable, just like the stability of a triangle, which can withstand greater pressure and external force, ensuring that the structure will not deform during the assembly of the rod valve core. The screw sleeve seat 52 and the bottom plate 1 are connected by an internal hexagon screw 9. The head of the internal hexagon screw 9 is internal hexagonal, which facilitates installation and disassembly in a narrow space. The connection is firm and reliable. The bottom plate 1 has a positioning hole, and the axis of the positioning hole coincides with the axis of the output end of the cylinder 41. This ensures that the rod valve core can be accurately positioned directly below the upper pressure head 6 during assembly, improving the assembly accuracy.

[0042] The implementation principle of the rod valve core press structure in this application embodiment is as follows: During the assembly of the rod valve core, the rod valve core is first placed on the limiting member 5. The joint threaded sleeve 53 of the limiting member 5 can be adjusted at an angle as needed to accurately position the rod valve core, which is convenient for the operator to assemble. The cylinder 41 drives the upper press head 6 to move along its axial direction to perform a tight fit operation on the placed valve core assembly. The reinforcement part 8 increases the stability of the joint threaded sleeve 53. The hexagonal socket screw 9 makes the threaded sleeve seat 52 and the base plate 1 tightly connected. The positioning hole ensures that the position of the rod valve core and the upper press head 6 are accurately corresponding. Compared with the traditional rod valve core assembly method, this structure improves the assembly accuracy and efficiency, reduces labor intensity, and ensures the consistency of product quality.
