A movable clamping block is slidably connected to the upper side of the sliding groove. A connecting rod is provided between the movable clamping blocks. An electric push rod is fixedly connected to the outer side of the middle part of the movable clamping block. The outer end of the electric push rod is fixedly connected to the support plate.

[0011] The beneficial effects of this utility model are: This utility model features clamping components symmetrically arranged on the operating table, in two sets. Each set of clamping components can hold three switches to be assembled at once. After the switches are clamped, one set of clamped switches can be assembled first. Once the assembly is complete, the other set of clamped switches can be assembled immediately.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] To address the problems existing in the prior art, this embodiment provides the following technical solution: a switch assembly fixture, comprising an operating table 1 and a support plate 2. The support plate 2 is positioned on the upper side of the center of the operating table 1, and clamping components 3 are symmetrically arranged on the upper end of the support plate 2, i.e., two sets of clamping components 3 are provided. The clamping components 3 can clamp and fix the switches to be assembled, and each set of clamping components 3 can clamp three switches to be assembled at a time. One set of clamped switches can be assembled first, and after processing, the other set of switches can be assembled. Simultaneously, one set of assembled switches can be disassembled, and the unassembled switches can be repositioned. After the other set of switches is assembled, the processing equipment can immediately move to the other set of re-clamped switches. This process is repeated, involving the clamping, fixing, assembly, and removal / replacement of the switch. These processes eliminate unnecessary time wastage, significantly improving switch assembly efficiency. Simultaneously, a monitoring mechanism 4 is installed in the middle of the clamping assembly 3. The pressure sensor 42 within the monitoring mechanism 4 monitors the pressure exerted by the clamping assembly 3 on the switch, effectively preventing overload during switch limit operation and thus avoiding deformation of the switch housing. Furthermore, a lifting mechanism 5 is installed on the lower side of the support plate 2. This lifting mechanism 5 adjusts the height of the support plate 2, allowing for height adjustment of the switch clamped by the clamping assembly 3 on the upper side of the support plate 2. The switch height can be adjusted to a suitable level for processing equipment, facilitating switch assembly and processing. like Figures 1-5As shown, a support plate 2 is provided on the upper side of the operating table 1, and clamping components 3 are symmetrically arranged on the upper end of the support plate 2. The clamping components 3 are set in two sets. The clamping assembly 3 includes a fixing frame 31, which is fixedly installed on the upper left and right sides of the support plate 2. At the same time, three sets of sliding grooves 32 are equally spaced inside the upper end of the fixing frame 31. The movable clamping block 33 is slidably installed on the upper side inside the sliding groove 32. The outer end of the middle part of the movable clamping block 33 is fixedly connected to an electric push rod 35. The outer end of the electric push rod 35 is fixedly connected and limited to the support plate 2. In addition, a connecting rod 34 is installed between the movable clamping blocks 33 for fixed connection. Furthermore, a rubber pad 36 is installed on the inner end of the movable clamping block 33. Meanwhile, fixed clamping blocks 37 are installed on the left and right sides of the inner end of the fixed frame 31. Three sets of slots are opened inside the fixed clamping block 37. The position of the slot inside the fixed clamping block 37 corresponds to the middle of each set of movable clamping blocks 33. In addition, rubber pads 38 are set on the outer end of the fixed clamping block 37. The switches to be assembled can be placed between the two sets of fixing brackets 31 and the fixing clamping blocks 37 set on the left and right sides of the upper end of the support plate 2, and will be located at the upper end of each set of fixing brackets 31. One side of the switch can be placed corresponding to the slot of the fixing clamping block 37. The fixing clamping block 37 has three sets of slots inside, which can fit the three switches with the slots inside the fixing clamping block 37. Then, the electric push rod 35 installed on the outer side of the middle of the moving clamping block 33 is opened. The output end of the electric push rod 35 can push the moving clamping block 33 to move inward, so that the moving clamping block 33 fits with the other side of the switch. That is, the moving clamping block 33 and the fixing clamping block 37 can clamp and limit the switch. The clamping components 3 set on each set at the upper end of the support plate 2 can limit the three switches at one time. After being fixed by the limit switch, the limit switch can be assembled using a screw-driving device (which consists of a drive slide rail and a smart electric screwdriver; the drive slide rail acts as a transmission component, its core function being to convert rotary motion into linear motion, achieving precise positioning and stable transmission through a lead screw or ball bearing guide, allowing the smart electric screwdriver to move; the smart electric screwdriver uses servo control, automatically adjusting torque and speed according to different screw sizes, precisely adjusting torque, speed, and tightening depth, supporting torque closed-loop control (accuracy ±3%) and recording tightening data in real time). During assembly, One set of switches can be assembled first. Once assembled, the screw-driving equipment can immediately move to the position of the other set of switches for assembly. At the same time, the worker can remove the assembled set of switches and immediately replace it with the unassembled switch, re-clamping and limiting it. After the other set of switches is assembled, the processing equipment can immediately move to the other set of re-clamped switches for assembly. This process is repeated. The clamping, fixing, assembly, and removal of the unassembled switch do not waste time and can greatly improve the efficiency of switch assembly. In addition, a rubber pad 36 is installed on the inner side of the movable clamping block 33, and a rubber pad 38 is installed on the inner side of the fixed clamping block 37. When the fixed clamping block 37 and the movable clamping block 33 clamp and fix the switch, the rubber pad 38 and the rubber pad 36 can fit against the outer side of the switch, thereby reducing the clamping pressure of the movable clamping block 33 and the fixed clamping block 37 on the switch and preventing scratches on the switch housing. Secondly, monitoring mechanisms 4 are installed on the inner and outer sides of the movable clamping blocks 33 in the middle of each group. Each monitoring mechanism 4 includes a cavity 41 inside the movable clamping block 33 in the middle of each group. A pressure sensor 42 is installed inside the cavity 41, and a wire is installed on the lower side of the pressure sensor 42. The wire connects to the movable clamping blocks 33 arranged in front and behind the outer sides of the middle movable clamping block 33. This allows the pressure sensor 42 to effectively detect the pressure when all three groups of movable clamping blocks 33 clamp the switch. The installation of the pressure sensor 42 allows for monitoring of the pressure on the movable clamping blocks 33. When the movable clamping block 33 contacts the switch, it can detect the clamping pressure of the movable clamping block 33. Once an overload of clamping pressure is detected, the indicator light 44 installed at the upper middle part of the movable clamping block 33 will light up. The indicator light 44 is connected to the pressure sensor 42 wirelessly (e.g., LoRa or Bluetooth). The indicator light 44 can serve as a warning to the worker. At the same time, through the control of the system, the movable clamping block 33 will stop pressing the switch, which can effectively prevent the switch housing from deforming when the movable clamping block 33 limits the switch. Secondly, a top cover 43 is provided on the upper side of the pressure sensor 42. A column is installed on one side of the inner end of the top cover 43. The outer side of the column is rotatably connected to the fixed sleeve installed on the upper part of the middle of the movable clamping block 33. A threaded hole is opened inside the other side of the top cover 43. A threaded hole is also opened on the upper part of the middle of the movable clamping block 33. When the top cover 43 rotates and fits against the upper end of the cavity 41, the threaded hole opened inside it will fit against the threaded hole opened on the upper side of the movable clamping block 33. Then, bolts can be inserted into the threaded holes of both to tighten and fix them. If the pressure sensor 42 detects an abnormality, the bolts of the top cover 43 and the movable clamping block 33 can be unscrewed and pulled out. Then, the top cover 43 can be rotated, and the upper side of the cavity 41 will be opened, which makes it easy to inspect the pressure sensor 42 inside. Secondly, each screw-driving processing equipment has a different height. By setting a lifting mechanism 5 on the lower side of the support plate 2, the lifting mechanism 5 is located in the middle of the operating table 1. The height of the entire support plate 2, clamping assembly 3 and monitoring mechanism 4 can be adjusted so that it can adapt to processing equipment of different heights. The lifting mechanism 5 includes a movable rod 52. The upper end of the movable rod 52 is fixedly connected to the lower end of the support plate 2 on both sides. At the same time, the movable rod 52 is slidably connected to the fixed slot frame 51. The lower end of the fixed slot frame 51 is fixedly connected to the lower end of the operating table 1. In addition, a connecting frame 53 is installed on the inner side of the lower end of the movable rod 52. A lead screw 54 is threadedly connected to the middle of the connecting frame 53. A motor 55 is installed at the lower end of the lead screw 54. By turning on the motor 55, the lead screw 54 installed at the upper end can be rotated. When the lead screw 54 rotates, the connecting bracket 53 connected to its outer thread will move up and down. The moving rod 52 installed at its outer end will move along with it and move upward inside the fixed slot frame 51. When the moving rod 52 moves, its upper end will drive the installed support plate 2 to move together. The clamping component 3 is set on the upper side of the support plate 2, and the monitoring mechanism 4 is set in the middle of the clamping component 3. The clamping component 3 and the monitoring mechanism 4 will move together, which can effectively adjust the height of the switch after it is fixed, so that it can adapt to processing equipment of different heights. The upper side of the control panel is equipped with a control panel, which contains a control system including sensors, a PIC controller, actuators, a power module, and a communication module. The power module can supply power to the entire system. The sensors, controllers, and actuators are responsible for parameters such as switch position and pressure and issuing commands. The sensors can be used to detect the state of the fixture, the actuators can effectively realize various actions of the fixture, and the communication module can be used to communicate with other supporting equipment. The electric push rod 35 (model HB-DJ801) in the clamping assembly 3 has its drive module connected to the PIC controller (model S7-200). The synchronous control is used to control the two electric push rods 35 on the outside of the clamping assembly 3 to start synchronous movement. The pressure sensor 42 (model FSR402) in the monitoring mechanism 4 is connected to the signal processing module in the control system to realize real-time monitoring and signal conversion. The motor 55 (model Z4-180-21) in the lifting mechanism 5 has its drive module connected to the PIC controller to control the opening of the motor 55.

[0017] The working principle of this switch assembly fixture is as follows: A support plate 2 is set on the upper side of the center of the operating table 1. Clamping components 3 are symmetrically arranged on the upper end of the support plate 2. Each clamping component 3 can clamp multiple switches at once. Two sets of clamping components 3 are symmetrically arranged on the upper side of the support plate 2. The screw-driving equipment can first assemble the switches clamped on one set of clamping components 3, and then switch to the other set for assembly. While assembling the other set, the assembled set of switches can be removed, and a new, unassembled switch can be placed and positioned. The processing equipment can move left and right to assemble the switches. Specifically, after the two sets of clamping components 3 each position three switches,... The screw-driving device can first assemble the upper limit switch of the clamping component 3 on the left side of the support plate 2. After the assembly is completed, the screw-driving device can immediately move to the upper side of the clamping component 3 on the right side of the support plate 2 to assemble the switch clamped and fixed by the clamping component 3 on the right side. At the same time, the assembled switch on the clamping component 3 on the left side can be removed and the switch that is not yet assembled can be reinstalled. After the switch on the clamping component 3 on the right side is assembled, it can immediately move to the upper side of the clamping component 3 on the left side to assemble the switch clamped thereon. By repeating this back and forth operation, the switch assembly operation can be carried out without interruption, which can reduce unnecessary time wasted during assembly and thus improve the overall efficiency of switch assembly. A monitoring mechanism 4 is also provided, which can detect the clamping pressure of the clamping components 3, and can prevent the clamping components 3 from clamping the switch and causing damage to the switch. In addition, a lifting mechanism 5 is provided, which can adjust the height of the entire clamping components 3, so that the switch after being limited can be used with processing and assembly equipment of different heights.

[0018] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
