Description

Technical Field

[0001] This invention relates to the field of bushing processing technology, and in particular to a grinding device for solenoid valve bushings. Background Technology

[0002] Solenoid valves are electromagnetically controlled industrial devices and belong to the actuator category. Among them, the bushing plays an important role in solenoid valves. It can support and position the valve stem or valve core, keeping it stable during movement. During the processing of the bushing, it needs to be positioned and fixed by a grinding device and clamping fasteners. Then, the burrs and protrusions on the outside of the bushing are ground off to ensure the smoothness of the bushing and facilitate subsequent assembly operations.

[0003] However, in the current solenoid valve bushing grinding equipment, the operating rod of the clamping and fixing part and the clamping block are unidirectionally driven. As a result, the clamping block can only be adjusted and positioned by the operating rod. The adjustment speed is slow and it cannot quickly reach the designated position. When clamping and positioning bushings with different outer diameters, the operation is cumbersome, the flexibility is poor, and the practicality is not high. Summary of the Invention

The control component enables unified control and positioning of the clamping mechanism, allowing for the positioning and fixing of bushings with different outer diameters. The device offers stable operation and features two operating modes: a locking control mode, where the clamping mechanism can only be controlled via a one-way transmission of the clamping rod, ensuring stable positioning and facilitating bushing grinding; and a free control mode, where the clamping mechanism can move freely, enabling rapid positioning of the bushing and simplifying the operation process for quickly clamping and positioning bushings with different outer diameters.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please refer to Figures 1 to 10 As shown: Example 1: This invention provides a grinding device for a solenoid valve bushing, including a mounting assembly 1. The mounting assembly 1 includes a clamping disc 101 and a fixed base 104. The clamping disc 101 is fixedly mounted on the top of the fixed base 104, and the fixed base 104 is fixedly mounted on the worktable of the grinding equipment. The mounting assembly 1 also includes a synchronizing disc 102 and two auxiliary clamping blocks 103. The synchronizing disc 102 is rotatably connected inside the clamping disc 101, and the two auxiliary clamping blocks 103 are inserted into the inside of the clamping disc 101. A control assembly 2 is also included. The control assembly 2 includes a clamping... The clamping mechanism consists of a positioning rod 201, a main clamping block 202, a clutch linkage block 203, and a switching control rod 204. The positioning rod 201 is rotatably connected inside the clamping disk 101, and the main clamping block 202 is inserted into the side of the clamping disk 101. The clutch linkage block 203 is inserted into the main clamping block 202, and the switching control rod 204 is inserted into the clutch linkage block 203. The main clamping block 202 and the two auxiliary clamping blocks 103 together form a clamping mechanism, and the included angle between the main clamping block 202 and the two auxiliary clamping blocks 103 is 120 degrees. The control component 2 also includes a status locking block 205, which is inserted into the interior of the main clamping block 202. The bottom of the status locking block 205 is provided with a locking top spring 2051, and the two ends of the locking top spring 2051 abut against the bottom of the status locking block 205 and the interior of the main clamping block 202, respectively.

[0031] In this embodiment, the main clamping block 202 and the two auxiliary clamping blocks 103 are provided with cross-shaped track blocks 2021 on their sides. The clamping disk 101 is provided with a track groove 1011 inside. The track blocks 2021 are inserted into the track groove 1011. The track groove 1011 can restrict the movement trajectory of the clamping mechanism through the track blocks 2021, thereby avoiding the phenomenon of the device jamming and failing due to skew or twisting during movement, and ensuring stable use.

[0032] In this embodiment, the track block 2021 has a synchronizing rod 2022 on its side, and the synchronizing disk 102 has an arc-shaped synchronizing groove 1021 inside. The synchronizing rod 2022 is inserted into the synchronizing groove 1021. In use, the control component 2 is in a locking control mode when in the reset state (the switching control rod 204 is not pressed by external force). The clutch linkage block 203 has a linkage top spring 2031 on its side, and the two ends of the linkage top spring 2031 abut against the side of the clutch linkage block 203 and the inside of the main clamping block 202, respectively. In this mode, under the action of the linkage top spring 2031, the threaded engagement between the threaded groove 2033 and the clamping positioning rod 201 is achieved. At this time, the clamping positioning rod 201 can achieve unidirectional control of the position and state of the clamping mechanism. The clamping positioning rod 201 has threads on its outside and passes through the inside of the main clamping block 202. The side of the linkage block 203 is provided with a mating thread groove 2033. When the state locking block 205 is inserted into the locking groove 2032, the mating thread groove 2033 and the rod body of the clamping positioning rod 201 are threadedly engaged. When the clamping positioning rod 201 is rotated, the clamping positioning rod 201 can drive the main clamping block 202 to move radially along the clamping disk 101 through the action of the mating thread groove 2033. During the movement of the main clamping block 202, the synchronizing rod 2022 on its side can drive the synchronizing disk 102 to rotate through the synchronizing groove 1021. When the synchronizing disk 102 rotates, it can also drive the two auxiliary clamping blocks 103 to move synchronously with the main clamping block 202 through the action of the other synchronizing grooves 1021 and synchronizing rods 2022. This changes the clamping distance of the clamping mechanism, which can realize the locking and fixing of bushings with different outer diameters, facilitates subsequent grinding operations, and ensures stable use.

[0033] In this embodiment, the clutch linkage block 203 has a locking groove 2032 at its bottom. When the clutch linkage block 203 is not pulled by an external force, under the action of the linkage top spring 2031 and the locking top spring 2051, the top of the state locking block 205 is inserted into the inside of the locking groove 2032, and the switching control lever 204 is located directly above the state locking block 205. In use, in the locking control mode, the clutch linkage block 203 is locked in its position inside the main clamping block 202, thereby enabling the mating threaded groove 2033 to stably engage with the clamping positioning lever 205. The threaded engagement of rod 01 enables the locking and fixing of the bushing. Under the action of the linkage top spring 2031 and the locking top spring 2051, the state locking block 205 is inserted into the inside of the locking groove 2032, thereby preventing the clutch linkage block 203 from moving radially in the clamping positioning rod 201. Thus, the threaded groove 2033 will never lose its threaded engagement with the clamping positioning rod 201. Furthermore, under the action of the separation top spring 2041, the switching control rod 204 will not push the state locking block 205 out of the locking groove 2032, resulting in extremely high stability.

[0034] In this embodiment, a release spring 2041 is provided on the outside of the switching control lever 204, and the two ends of the release spring 2041 abut against the top of the switching control lever 204 and the inside of the clutch linkage block 203, respectively. In use, by pressing and pulling the switching control lever 204, the control component 2 can be switched to the free control mode. When the switching control lever 204 is pressed, the release spring 2041 is compressed. The bottom of the switching control lever 204 can push the state locking block 205 out of the locking groove 2032 by abutting and squeezing. Thus, the locking state of the clutch linkage block 203 inside the main clamping block 202 is released. Afterwards, when the switching control lever 204 is pulled, the clutch linkage block 203 can move synchronously and compress the linkage spring 2031, thereby releasing the thread between the mating thread groove 2033 and the clamping positioning rod 201. The clamping mechanism is in an unlocked state. Afterwards, the main clamping block 202 can be pulled directly to change its position. Simultaneously, under the action of the synchronous disc 102, the two auxiliary clamping blocks 103 will also move synchronously to change their positions. This allows for rapid and wide-range adjustment of the clamping distance, making operation convenient and positioning fast. After positioning, releasing the switching control lever 204 causes the switching control lever 204 and the clutch linkage block 203 to automatically reset under the combined action of the linkage top spring 2031, the separation top spring 2041, and the locking top spring 2051. The state locking block 205 will then re-insert into the locking groove 2032, restoring the locking control mode of the control component 2. Afterwards, the clamping mechanism can be finely adjusted and tightened / untightened using the clamping positioning lever 201. Operation is convenient, and two control modes can be selected as needed, offering high flexibility and adaptability.

[0035] The specific usage and function of this embodiment: In this invention, the usage mode of the control component 2 can be selected as needed. The control component 2 has two operating modes. One is the locking control mode, in which the clamping and positioning rod 201 can only be used for adjustment through the one-way transmission clamping mechanism. The positioning is stable and convenient for grinding operations on the bushing. The other is the free control mode, in which the clamping mechanism can move freely and can quickly position the usage position, thus facilitating the operation of quickly clamping and positioning bushings with different outer diameters and simplifying the operation process. When the control component 2 is in the reset state (the switching control rod 204 is not pressed by external force), it is in the locking control mode. In this mode, under the action of the linkage top spring 2031, it cooperates with the thread groove 2033 and the clamping and positioning. The rods 201 are threaded together, allowing for unidirectional control of the clamping mechanism's position and status via the clamping positioning rod 201. When the clamping positioning rod 201 is rotated, it engages with the threaded groove 2033 to drive the main clamping block 202 to move radially along the clamping disk 101. During this movement, the synchronizing rod 2022 on the side of the main clamping block 202 drives the synchronizing disk 102 to rotate via the synchronizing groove 1021. As the synchronizing disk 102 rotates, it, through the engagement of the remaining synchronizing grooves 1021 and synchronizing rods 2022, causes the two auxiliary clamping blocks 103 to move synchronously with the main clamping block 202, thus changing the clamping distance of the clamping mechanism and enabling the clamping of bushings with different outer diameters. For locking and securing, facilitating subsequent grinding operations, in locking control mode, the clutch linkage block 203 is locked in its position inside the main clamping block 202, allowing the mating thread groove 2033 to stably engage with the threaded part of the clamping positioning rod 201, thus achieving locking and securing of the bushing. Under the action of the linkage top spring 2031 and the locking top spring 2051, the state locking block 205 is inserted into the locking groove 2032, preventing the clutch linkage block 203 from moving radially in the clamping positioning rod 201. This ensures that the mating thread groove 2033 never loses its threaded engagement with the clamping positioning rod 201. Furthermore, under the action of the release top spring 2041, the switching control lever 204 will not release the state locking block. 205 is ejected from the locking groove 2032. By pressing and pulling the switching control lever 204, the control component 2 can be switched to the free control mode. When the switching control lever 204 is pressed, it compresses the release spring 2041. The bottom of the switching control lever 204 can push the state locking block 205 out of the locking groove 2032 through abutment and compression. Thus, the locking state of the clutch linkage block 203 inside the main clamping block 202 is released. Afterward, pulling the switching control lever 204 can drive the clutch linkage block 203 to move synchronously and compress the linkage spring 2031, thereby releasing the threaded engagement between the mating thread groove 2033 and the clamping positioning rod 201. That is, the clamping mechanism is now in the unlocked state.Subsequently, the position of the main clamping block 202 can be changed by directly pulling it. Simultaneously, under the action of the synchronous disc 102, the two auxiliary clamping blocks 103 will also move synchronously to change their positions. This allows for rapid and wide-range adjustment of the clamping distance, making operation convenient and positioning quick. After positioning, releasing the switching control lever 204 causes the switching control lever 204 and the clutch linkage block 203 to automatically reset under the combined action of the linkage top spring 2031, the separation top spring 2041, and the locking top spring 2051. The state locking block 205 will then re-insert into the locking groove 2032, restoring the locking control mode of the control component 2. Afterward, the clamping mechanism can be finely adjusted and tightened / untightened using the clamping positioning lever 201, making operation convenient.
