Description

Technical Field

[0001] This utility model relates to the field of cutting machine spindle technology, and in particular to a fully automatic silicone pad cutting machine spindle assembly. Background Technology

[0002] In fully automatic silicone gasket cutting equipment, the spindle assembly, as the core actuator, bears the crucial task of driving the cutting tool to rotate and accurately cut the silicone gasket. The stability and strength of its connection play a decisive role in cutting quality and equipment operating efficiency. Existing fully automatic silicone gasket cutting machine spindle assemblies have some significant technical defects in their connection with the cutting tool or other transmission components. During the cutting process, due to the material characteristics of the silicone gasket and the requirements of the cutting process, the spindle needs to frequently rotate at high speed and start / stop. This generates significant vibration and torque between the spindle and the connecting components. Traditional keyed or threaded connections are prone to loosening under long-term alternating loads, causing the cutting tool to shift position, thus affecting cutting accuracy and increasing the dimensional error of the cut silicone gaskets, failing to meet the demands of high-precision production. Utility Model Content

[0003] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that traditional key connection or threaded connection methods are prone to loosening under long-term alternating load. To address this, we propose a fully automatic silicone gasket cutting machine spindle assembly.

[0004] To achieve the above objectives, this application adopts the following technical solution: a fully automatic silicone gasket cutting machine spindle assembly, including a mounting plate and a mounting seat fixedly connected to the outer wall of the mounting plate. The inner wall of the mounting seat is provided with a bearing body, and the inner wall of the bearing body is mounted with a spindle body. The outer wall of the spindle body is provided with a mounting cavity, and the inner wall of the mounting cavity is slidably connected with a slider body. One end of the slider body is fixedly connected with a reinforcing block, and the end of the slider body away from the reinforcing block is fixedly connected with an elastic element. The end of the elastic element away from the slider body is fixedly connected to the bottom of the mounting cavity.

[0005] Furthermore, in the relaxed state of the elastic element, the slider body abuts against the opening of the mounting cavity, and the reinforcing block protrudes from the opening of the mounting cavity, facilitating quick docking during subsequent assembly.

[0006] Furthermore, the reinforcing block is a frustum structure and is a component made of rubber. The rubber material can generate indentation deformation through elasticity, which not only buffers the assembly impact but also provides triggering conditions for the linkage of subsequent components, while enhancing the fit and sealing after connection.

[0007] Furthermore, the reinforcing block has an internal movable cavity, and a push rod body is axially connected to the inner wall of the movable cavity. An auxiliary push block is axially connected to one end of the push rod body away from the inner wall of the movable cavity.

[0008] Furthermore, a sliding groove is provided on one side of the slider body connected to the reinforcing block, and the auxiliary push block is slidably connected to the inner wall of the sliding groove.

[0009] Furthermore, a reset spring is fixedly connected to one side of the auxiliary push block, and the reset spring is fixedly connected to the inner wall of the sliding groove.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] In this invention, after the installation is completed, the axial reaction force of the elastic element prevents the reinforcing block from sinking excessively, ensuring the axial fit of the connection and preventing axial loosening after installation. The return spring transmits the radial reaction force to the auxiliary push block, which presses against the inner wall of the mounting hole from the side, limiting the radial displacement of the external component. Finally, the spindle assembly and the external component form a stable connection. Even if the spindle body rotates at high speed and bears cutting torque during subsequent cutting operations, the connection can resist vibration and torque impact, ensuring cutting accuracy and equipment operation stability. This solves the problem that traditional key or threaded connections are prone to loosening under long-term alternating loads, causing the cutting tool to shift position, which in turn affects cutting accuracy and increases the dimensional error of the cut silicone gasket, failing to meet the high-precision production requirements.

[0019] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0020] Reference Figures 1-5 As shown, in order to solve the problem that traditional keyed or threaded connections are prone to loosening under long-term alternating loads, causing the cutting tool to shift and affecting cutting accuracy, resulting in increased dimensional errors in the cut silicone gaskets and failing to meet the requirements of high-precision production, the following preferred technical solution is provided.

[0021] A fully automatic silicone gasket cutting machine spindle assembly includes a mounting plate 1 and a mounting base 2 fixedly connected to the outer wall of the mounting plate 1. A bearing body 3 is disposed on the inner wall of the mounting base 2, and a spindle body 4 is mounted on the inner wall of the bearing body 3. Through the hierarchical assembly of the mounting plate 1, mounting base 2, bearing body 3, and spindle body 4, the mounting plate 1 provides an installation reference for the entire assembly. The bearing body 3 reduces the rotational friction of the spindle body 4 and ensures its coaxiality, laying a stable foundation for subsequent cutting operations. An installation cavity 6 is formed on the outer wall of the spindle body 4. A slider body 7 is slidably connected to the inner wall of the installation cavity 6. A reinforcing block 8 is fixedly connected to one end of the slider body 7, and an elastic element 9 is fixedly connected to the end of the slider body 7 away from the reinforcing block 8. The end of the elastic element 9 away from the slider body 7 is fixedly connected to the bottom of the installation cavity 6.

[0022] When the elastic element 9 is in a relaxed state, the slider body 7 abuts against the opening of the mounting cavity 6, and the reinforcing block 8 protrudes from the opening of the mounting cavity 6. This state provides a positioning structure for connecting the cutting tool or transmission component, which facilitates quick docking during subsequent assembly.

[0023] The reinforcing block 8 is a frustum structure made of rubber. The frustum structure can fit into the inner wall of the mounting hole for guidance, while the rubber material can use its elasticity to generate concave deformation, which not only buffers the assembly impact, but also provides the trigger condition for the linkage of subsequent components, and enhances the fit and sealing after connection.

[0024] The reinforcing block 8 has a movable cavity 10 inside. The inner wall of the movable cavity 10 is axially connected to the push rod body 11, and the end of the push rod body 11 away from the inner wall of the movable cavity 10 is axially connected to the auxiliary push block 12. The movable cavity 10 provides space for the reinforcing block 8 to be recessed and deformed, and at the same time provides a fulcrum for the push rod body 11 to rotate. When the reinforcing block 8 is compressed and recessed, its inner wall will squeeze the push rod body 11, driving it to rotate around the axis.

[0025] A sliding groove 13 is provided on one side of the slider body 7 that connects to the reinforcing block 8, and the auxiliary push block 12 is slidably connected to the inner wall of the sliding groove 13. The sliding groove 13 provides a directional sliding track for the auxiliary push block 12, ensuring that it moves stably in the radial direction under the push of the push rod body 11, and avoiding motion disorder caused by deformation and displacement of the reinforcing block.

[0026] A return spring 14 is fixedly connected to one side of the auxiliary push block 12, and the return spring 14 is fixedly connected to the inner wall of the sliding groove 13. One end of the return spring 14 is fixed to the sliding groove 13, and the other end is connected to the auxiliary push block 12, forming a retractable elastic constraint structure, which together with the elastic element 9, the push rod body 11, etc., constitutes a linkage closed loop.

[0027] Specifically, before installation, the elastic element 9 is in a relaxed state, with its supporting slider body 7 abutting against the opening of the mounting cavity 6, causing the frustum-shaped rubber reinforcing block 8 to protrude from the opening. At this time, the auxiliary push block 12 is housed in the sliding groove 13 under the constraint of the return spring 14, and the push rod body 11 maintains its initial posture in the movable cavity 10. When the mounting hole of the external component is fitted into the end of the main shaft body 4, the inner wall of the mounting hole first contacts the reinforcing block 8 protruding from the opening and applies a squeezing force, triggering the linkage operation of the entire structure: the squeezing force of the mounting hole causes the rubber reinforcing block 8 to undergo concave deformation, simultaneously driving the slider body 7 fixed thereto to slide along the inner wall of the mounting cavity 6 towards the bottom of the cavity, directly compressing the elastic element 9. After being compressed, the elastic element 9 quickly accumulates axial reaction force, which acts in the opposite direction on the slider body 7 and the reinforcing block 8, offsetting part of the concave deformation and pushing the reinforcing block 8 to fit tightly against the inner wall of the mounting hole, forming preliminary axial support and sealing.

[0028] Simultaneously, the concave deformation of the reinforcing block 8 causes the inner wall of the internal movable cavity 10 to contract synchronously. The extrusion shaft, connected to the push rod body 11 on the inner wall of the movable cavity, forces the push rod body 11 to rotate around the pivot point. The other end of the push rod body 11 then pushes the auxiliary push block 12 outward along the directional track of the sliding groove 13. During this process, the return spring 14 is stretched and accumulates radial reaction force. This force further strengthens the pressing force of the auxiliary push block 12 against the inner wall of the mounting hole, forming a radial lock.

[0029] After installation, the axial reaction force of the elastic element 9 prevents the reinforcing block 8 from being excessively recessed, ensuring the axial fit of the connection and preventing axial loosening after installation. The return spring 14 transmits the radial reaction force to the auxiliary push block 12, which presses against the inner wall of the mounting hole from the side, limiting the radial displacement of the external component. Finally, the spindle assembly and the external component form a stable connection. Even if the spindle body 4 rotates at high speed and bears cutting torque in subsequent cutting operations, the connection can resist vibration and torque impact, ensuring cutting accuracy and equipment operation stability. This solves the problem that traditional key or threaded connections are prone to loosening under long-term alternating loads, causing the cutting tool to shift position, which in turn affects cutting accuracy and increases the dimensional error of the cut silicone pad, failing to meet the high-precision production requirements.

[0030] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
