DETAILED DESCRIPTION

[0023] The following is a further non-limiting detailed description of the technical solution of the present invention in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-7 The present invention provides a technical solution: a clamping device for processing an inner opening handle assembly with a pressure self-adjusting type, comprising a clamping mechanism and a pressure self-adjusting mechanism, the clamping mechanism comprising a base 1, a chamber 2 and two sets of holding parts, and the pressure self-adjusting mechanism is arranged inside the chamber 2;

[0025] The two sets of supporting parts include two fixed plates 3, a pin, a clamping rod 5 and a clamping plate 6. The pressure self-adjusting mechanism includes a motor 21, an output shaft 22, a telescopic joint 23, a threaded sleeve 24, a threaded rod 25 and two connecting parts. The two connecting parts include two hinges 26 and a connecting plate 27. The chamber 2 is fixedly installed above the base 1. A placement block 4 is fixed above the chamber 2. The fixed plate 3 is fixedly installed above the base 1 and is located on one side of the chamber 2. The clamping rod 5 is connected between the two fixed plates 3 through a pin. The clamping plate 6 is fixedly installed. It is mounted on the inner end of the clamping rod 5 and is located on one side of the placement block 4. The motor 21 is fixedly mounted on the bottom of the inner wall of the chamber 2. The telescopic joint 23 is fixedly connected to the output end of the motor 21 through the output shaft 22. The threaded rod 25 is fixedly mounted on the upper part of the inner wall of the chamber 2. The threaded sleeve 24 is fixedly mounted on the upper end of the telescopic joint 23 and is threadedly connected to the threaded rod 25. One of the hinges 26 is bearing-mounted on the outer side of the threaded sleeve 24 and is connected to the other hinge 26 through the connecting plate 27. The other hinge 26 is fixedly mounted on one side of the lower end of the clamping rod 5.

[0026] The operator places the inner opening handle assembly on the placement block 4, and then the motor 21 is started, and the telescopic joint 23 is driven to rotate through the output shaft 22, and the telescopic joint 23 drives the threaded sleeve 24 to rotate, and the threaded sleeve 24 rotates upward through the thread direction of the threaded rod 25, and at the same time the telescopic joint 23 is pressed to shorten, and the threaded sleeve 24 pulls the connecting plate 27 to move upward through one of the hinges 26, and the outer end of the connecting plate 27 rotates through the other hinge 26, thereby pushing the clamping rod 5 outward, and the clamping rod 5 rotates through the pin shaft, thereby driving the clamping plate 6 to move inward, clamping the inner opening handle assembly, thereby fixing the inner opening handle assembly, and then punching the inner opening handle assembly. The operation is automated, convenient and efficient, the punching efficiency is greatly improved, and the clamping force is stable, and the inner opening handle assembly will not be damaged, which plays a role in protecting the inner opening handle assembly, and synchronously does not affect the punching quality.

[0027] The motor 21 is provided with a model input module, a hole recognition module and a rotation control module. The model input module is used to input the model of the inner opening handle assembly through the terminal. The hole recognition module is used to identify the number of holes required to be opened according to the model of the inner opening handle assembly. The rotation control module is used to control the rotation angle of the motor 21 according to the number of holes required to be opened.

[0028] The control method of the rotation control module is that the more holes need to be opened, the greater the rotation angle of the motor 21, so that the force with which the clamping plate 6 clamps the inner opening handle assembly is greater, and vice versa. On the one hand, the clamping force can be guaranteed, thereby avoiding loosening when punching holes in the inner opening handle assembly and affecting the punching quality. On the other hand, it can relatively avoid excessive clamping force of the inner opening handle assembly, resulting in deformation and affecting the quality of the inner opening handle assembly itself.

[0029] The outer side of the output shaft 22 is fixed with a sector tooth 221, the inner wall of the chamber 2 is fixed with a slide rail 28, the inner wall of the slide rail 28 is slidably connected with a tooth plate 281, and the tooth plate 281 and the sector tooth 221 are meshed with each other, and elastic springs 282 are fixed between the two sides of the front side of the tooth plate 281 and the two sides of the front side of the inner wall of the slide rail 28;

[0030] The front and rear sides of the tooth plate 281 are both fixed with impact rods 283, one end of the impact rod 283 is spherical, and the impact rod 283 on the rear side is in contact with the inner wall of the chamber 2;

[0031] The output shaft 22 rotates, driving the fan teeth 221 to rotate. The fan teeth 221 drives the tooth plate 281 to move through the engagement. The tooth plate 281 slides in the slide rail 28, and the elastic spring 282 is deformed by the force, driving the impact rod 283 on the rear side away from the inner wall of the chamber 2. Then the fan teeth 221 disengage from the tooth plate 281, and the elastic spring 282 generates a reaction force, so that the impact rod 283 is quickly reset, thereby impacting the inner wall of the chamber 2. The impact generates vibration, so as to detect whether the clamping plate 6 is clamped tightly by the vibration, and detect whether it is loose. At the same time, the vibration can also shake off the waste residue produced by the punching on the clamping plate 6, so as to avoid the subsequent clamping being affected by the waste residue and causing the clamping of the inner opening handle assembly to be unstable. In this way, whether the clamping of the inner opening handle is loose is detected, and compared with the manual pulling of the inner opening handle assembly to detect whether it is loose, the detection is more convenient and faster, and it can prevent the deformation of the inner opening handle assembly caused by manual pulling and affecting the quality.

[0032] An air pressure chamber 29 is fixed to the inner wall of the chamber 2, and an air pressure plate 291 is slidably connected to the inner wall of the air pressure chamber 29. A connecting rod 292 is fixed to the rear side of the air pressure plate 291, and the rear end of the connecting rod 292 is fixedly connected to the upper surface of the tooth plate 281. An air blowing pipe 7 is fixed to both the left and right sides above the chamber 2, and the air blowing pipe 7 is connected to the rear side of the air pressure chamber 29 through a pipeline.

[0033] After the tooth plate 281 moves, the air pressure plate 291 is driven to slide along the inner wall of the air pressure chamber 29 through the connecting rod 292. After that, after the motor 21 is reset, the reaction force generated by the elastic spring 282 resets the tooth plate 281, thereby driving the air pressure plate 291 to reset, so that the air pressure plate 291 slides back and forth along the inner wall of the air pressure chamber 29, and the gas on the rear side of the air pressure plate 291 is squeezed and ejected through the blowing pipe 7, so that the waste residue on the clamping plate 6 can be further blown off, further avoiding the waste residue from affecting the clamping, fully protecting the stability of the clamping, and avoiding the waste residue generated by drilling, so as to avoid the waste residue from affecting the clamping when the inner opening handle assembly is placed on the mounting block 4 later, resulting in unstable clamping.

[0034] An elastic telescopic rod 8 is fixed to the inner wall of the chamber 2, a push plate 81 is fixed to one end of the elastic telescopic rod 8, and the push plate 81 is in contact with one side of the connecting plate 27;

[0035] The elastic telescopic rod 8 is connected to the front side pipeline of the air pressure chamber 29, and a pressure valve and an air chamber are arranged in the pipeline. The pressure valve is located on the left side of the air chamber. The front side of the air pressure chamber 29 is connected to the external pipeline, and a one-way valve is arranged in the pipeline. The elastic telescopic rod 8 is connected to the external control valve pipeline.

[0036] A spring 261 is provided inside the hinge 26 outside the threaded sleeve 24;

[0037] When the air pressure plate 291 slides back and forth along the inner wall of the air pressure chamber 29, gas is extracted from the outside through the pipeline and injected into the air chamber. When the air pressure in the air chamber reaches the pressure bearing limit of the pressure valve, it opens, and the gas quickly enters the elastic telescopic rod 8 through the pipeline, causing it to quickly extend, thereby driving the push plate 81 to push the connecting plate 27, and the spring 261 is deformed under force. After that, the external control valve opens, and the elastic telescopic rod 8 is reset, so that the push plate 81 is out of contact with the connecting plate 27. The spring 261 produces a reaction to reset the connecting plate 27. Through the connecting plate 27, the clamping plate 6 clamps the inner opening handle assembly and shakes it back and forth to further detect whether it will be loose, so as to ensure that the inner opening handle assembly is fully clamped, so as to facilitate the smooth operation of subsequent punching. At this time, the inner opening handle assembly is clamped and punched multiple times, thereby generating more waste slag. Shaking can further shake off the waste slag, fully ensuring the stability of clamping, and fully avoiding the influence of waste slag on clamping.

[0038] A contact sensing module is disposed inside the push plate 81, an electromagnetic block is disposed inside the tooth plate 281, and the spherical part of the impact rod 283 is hollow inside and elastic, and is filled with magnetorheological fluid;

[0039] The contact sensing module is electrically connected to the electromagnetic block, and the electromagnetic block generates magnetism after passing through. The contact sensing module is used to control the power on and off of the electromagnetic block through the contact between the push plate 81 and the connecting plate 27;

[0040] When the push plate 81 contacts the connecting plate 27, the electromagnetic block is energized to generate magnetism, which makes the magnetorheological fluid become viscous, so that the impact rod 283 hits the chamber 2 with higher intensity, the vibration intensity is higher, and the effect of cleaning waste residue is better. After the push plate 81 contacts the connecting plate 27 for the next time, the electromagnetic block is de-energized, and the high-intensity impact will not be excessive, thereby avoiding affecting the stability of the clamping pressure.
