Description

Technical Field

[0001] This utility model relates to the field of switch processing technology, and in particular to a processing equipment for automotive ignition switches. Background Technology

[0002] The automotive ignition switch is an important component of the automotive electrical system. It is responsible for controlling the starting and stopping of the car, and can freely turn the main circuit of the ignition coil on or off. It can also control the instrument lighting circuit and the starting relay circuit. In order to ensure the stability of the machining process, a fixture is often used to hold the switch component during the machining of automotive ignition switches.

[0003] A search revealed that Chinese Patent Publication No. CN211841668U discloses a processing equipment for automotive ignition switches. The equipment includes a threaded disc that rotates via an adjusting valve, thereby causing the chuck block in the chuck limiting groove to slide radially. The diameter of the clamping device can be adjusted. Simultaneously, the chuck on the connecting rod rotates via a rotating valve, and the chuck teeth are fixed with rivets. The rotation angle can be adjusted at will, facilitating processing.

[0004] In the actual use of the aforementioned processing equipment, the clamping block moves and adjusts by the interaction between the threaded teeth at the bottom of the clamping block and the threads on the threaded disc. Each time the ignition switch is clamped and released, the bottom of the clamping block needs to have a lot of contact friction with the threaded disc. During long-term high-intensity processing, the threaded teeth at the bottom of the clamping block and the threads on the threaded disc will wear out quickly, which will affect the service life of the processing equipment. Therefore, a processing equipment for automotive ignition switches is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automotive ignition switch processing equipment, which aims to improve the problem that the processing equipment in the prior art will wear out quickly, resulting in a reduced service life.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automotive ignition switch processing device, comprising a base, a fixed frame fixedly connected to the upper surface of the base, a chuck fixedly connected to the inner bottom surface of the fixed frame, a limiting groove formed on the outer wall surface of the chuck, a clamping block inserted into the limiting groove, a guide unit provided on the outer side of the clamping block, the guide unit acting to guide and limit the movement of the clamping block, a lifting ring plate sleeved on the outer side of the chuck, a moving unit provided on the outer side of the lifting ring plate, the moving unit acting to drive the lifting ring plate to perform linear movement in the up and down direction.

[0007] As a further description of the above technical solution:

[0008] The chuck has a support plate inside, and a lead screw is fixedly connected to the bottom surface of the support plate. The bottom end of the lead screw passes through the fixed frame, and a handle is fixedly connected to the bottom end of the lead screw. The handle has anti-slip texture on its outer side.

[0009] As a further description of the above technical solution:

[0010] The guiding unit includes a guide bar, which is fixedly connected to the outer surface of the clamping block, and the inner wall surface of the limiting through groove is provided with a guide groove.

[0011] As a further description of the above technical solution:

[0012] The guide bar is slidably connected to the inside of the guide groove.

[0013] As a further description of the above technical solution:

[0014] The moving unit includes a side plate, which is fixedly connected to the outside of the lifting ring plate, and an electric push rod is fixedly connected to the upper surface of the base.

[0015] As a further description of the above technical solution:

[0016] The top output end of the electric push rod passes through the fixed frame, and the top output end of the electric push rod is fixedly connected to the bottom surface of the side plate.

[0017] As a further description of the above technical solution:

[0018] The upper end of the inner wall of the lifting ring plate is inclined towards the end away from the chuck, and the bottom end of the clamping block on the side away from the chuck is in contact with the inner wall of the lifting ring plate.

[0019] As a further description of the above technical solution:

[0020] A rubber pad is fixedly connected to one side of the clamping block near the center of the chuck.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, through the cooperation of the limiting through groove, guide unit, rubber pad, lifting ring plate and moving unit, multiple clamping blocks can be driven to move quickly, so as to quickly clamp the ignition switch placed inside the chuck without the need for thread adjustment. Since the contact surface between the lifting ring plate and the clamping block is small, the wear generated will be relatively low, which can extend the service life of the processing equipment and improve the processing efficiency.

[0023] 2. In this utility model, the height of the ignition switch placed inside the chuck can be quickly adjusted by the cooperation of the support plate, lead screw and handle, so that the ignition switch can be stably placed in the clamping position of the clamping block, avoiding displacement that would affect the clamping effect.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 - Figure 2 One embodiment of this utility model is a processing equipment for automotive ignition switches, including a base 1. A fixing frame 2 is fixedly connected to the upper surface of the base 1. The fixing frame 2 and the base 1 are supported and connected by a fixing rod, so that a gap can be left between the fixing frame 2 and the base 1 to facilitate the installation of components. A chuck 3 is fixedly connected to the inner bottom surface of the fixing frame 2, and the ignition switch can be placed inside the chuck 3 for clamping and processing.

[0032] Reference Figure 2 - Figure 4A number of limiting slots 4 are formed on the outer wall surface of the chuck 3. These limiting slots 4 are arranged in a linear array on the outer side of the chuck 3. Clamping blocks 5 are inserted into the limiting slots 4. The number and position of the clamping blocks 5 are adapted to the number and position of the limiting slots 4. The clamping blocks 5 can move linearly along the path of the limiting slots 4 inside the limiting slots 4. A rubber pad 6 is fixedly connected to the side surface of the clamping block 5 near the center of the chuck 3. The rubber pad 6 can increase the contact friction between the clamping block 5 and the ignition switch. To prevent hard contact with the ignition switch and damage to it, a guide unit is provided on the outer side of the clamping block 5. The guide unit includes a guide strip 51, which is fixedly connected to the outer surface of the clamping block 5. A guide groove 52 is provided on the inner wall surface of the limiting through groove 4. The guide strip 51 is slidably connected to the inside of the guide groove 52. Through the cooperation of the guide strip 51 and the guide groove 52, the movement of the clamping block 5 can be further limited to avoid deviation during movement, which would affect the clamping of the ignition switch.

[0033] A lifting ring plate 7 is fitted on the outer side of the chuck 3. The upper end of the inner wall of the lifting ring plate 7 is inclined away from the chuck 3. The bottom end of the clamping block 5 on the side away from the chuck 3 is in contact with the inner wall of the lifting ring plate 7. When the lifting ring plate 7 moves upward, it will squeeze the clamping block 5. At this time, the clamping block 5 will move and adjust into the chuck 3 with the cooperation of the limiting groove 4 and the guide unit. After the ignition switch is placed into the chuck 3, the lifting ring plate 7 can be driven to press the clamping block 5 upward, so that the clamping block 5 moves into the chuck 3 under the limitation of the limiting groove 4 and the guide unit. The ignition switch is clamped and fixed with the rubber pad 6, which facilitates the processing operation.

[0034] A moving unit is provided on the outer side of the lifting ring plate 7. The moving unit includes a side plate 71, which is fixedly connected to the outer side of the lifting ring plate 7. An electric push rod 72 is fixedly connected to the upper surface of the base 1. The top output end of the electric push rod 72 passes through the fixed frame 2 and is fixedly connected to the bottom surface of the side plate 71. When the electric push rod 72 is started, it can drive the lifting ring plate 7 to move linearly up and down through the side plate 71, thereby quickly adjusting the position of the clamping block 5.

[0035] Reference Figure 2 - Figure 3The chuck 3 has a support plate 8 inside, and a lead screw 9 is fixedly connected to the bottom surface of the support plate 8. The bottom end of the lead screw 9 passes through the fixed frame 2, and the lead screw 9 and the fixed frame 2 are threaded together. When the lead screw 9 rotates, it can move linearly up and down relative to the fixed frame 2. When the lead screw 9 moves, it can drive the support plate 8 to move synchronously. After the ignition switch is placed above the support plate 8, the lead screw 9 can be rotated to drive the support plate 8 to move and adjust the position of the ignition switch so that the ignition switch can be moved to the clamping block 5 for clamping and fixing, so as to avoid displacement and failure to clamp. The bottom end of the lead screw 9 is fixedly connected to a handle 10. The outer side of the handle 10 is provided with anti-slip texture. The operator can quickly turn the lead screw 9 through the handle 10. The anti-slip texture can increase the friction between the operator's palm and the handle, so as to avoid slipping.

[0036] Working principle: Place the ignition switch above the support plate 8, then turn the handle 10 to move the support plate 8 up and down, so that the ignition switch moves to the clamping position of the clamping block 5. Then, start the electric push rod 72 to move the lifting ring plate 7 upward. At this time, the inclined inner wall of the lifting ring plate 7 will squeeze the clamping block 5, so that the clamping block 5 moves into the chuck 3 under the limit of the limiting through groove 4 and the guide unit. The rubber pad 6 clamps and fixes the ignition switch, which is convenient for processing operations. No thread adjustment is required. Since the contact surface between the lifting ring plate 7 and the clamping block 5 is small, the wear generated will be relatively low, which can extend the service life of the processing equipment and improve the processing efficiency.

[0037] 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.
