[0025] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0026] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0027] Reference Figures 1-5 A product clamping and fixing device includes: a clamping base 200 disposed on a laser engraving and welding workbench, wherein the top of the clamping base 200 is provided with a fixing inner groove 201; two clamping heads 202 disposed in the fixing inner groove 201 for clamping the product; and a pressure plate 300 mounted on the clamping base 200 for pressing and fixing the product.

[0028] In this embodiment, the product is positioned in the fixed inner groove 201 area, and the two clamping heads 202 and the pressure block hold the product shape for positioning. This method of fixing the product can improve the accuracy and consistency of welding, ensure product quality, and adapt to the shape and size of specific products to achieve precise spot welding. One clamping can perform spot welding on multiple surfaces, reducing the number of processing clamps and reducing manpower requirements. It also effectively improves the stability of product processing dimensions.

[0029] The clamping base 200 includes: two grooves 203, which are respectively formed on the two side walls of the fixed inner groove 201, and the clamping head 202 is connected in the groove 203; a displacement sensor 205, which is installed on the inner wall of the groove 203 and is used to detect the displacement state of the clamping head 202; and an elastic element 204, one end of which is installed on the inner wall of the groove 203 and the other end of which is installed on the clamping base 200.

[0030] The clamping head 202 includes: a positioning head 400, mounted on the clamping head 202; and a second power source 401, mounted on the bottom of the clamping head 202, the power shaft of the second power source 401 being connected to the positioning head 400, and the second power source 401 being connected to the displacement sensor 205 via a controller. Both clamping heads 202 have beveled surfaces at their ends that are close to each other.

[0031] The aforementioned groove 203 allows for precise sliding engagement with the clamping head 202, ensuring stability and guidance of the clamping head 202 as it moves within the groove 203. The displacement sensor 205 is a high-precision Hall effect displacement sensor, capable of real-time and accurate detection of the displacement state of the clamping head 202 within the groove 203. Once the position of the clamping head 202 changes, the displacement sensor 205 immediately transmits a signal to the controller. When a product is placed into the fixed inner groove 201, the product simultaneously presses against both clamping heads 202, causing displacement. The displacement sensor 205 detects this displacement change. Once the clamping head 202 stops moving, the controller can activate the second power source 401. The second power source 401 drives the positioning head 400 to move, which securely supports the clamping head 202 within the groove 203, preventing loosening after the clamping head 202 has secured the product. The second power source 401 can be a cylinder or a linear motor. The elastic element 204 can be a spring or a spring block. The main function of the elastic element 204 is to provide an initial preload for the clamping head 202, so that the clamping head 202 can be kept in a relatively stable position without external driving force. When the clamping head 202 moves under the action of external power, the elastic element 204 will deform accordingly and store elastic potential energy. When the external power disappears, the elastic element 204 can use the stored potential energy to reset the clamping head 202, thus ensuring the adaptability and reliability of the device.

[0032] When the two clamping heads 202 gradually approach and clamp the part under the action of external power, the inclined surface can play a guiding role, making it easier for the part to enter the predetermined position between the two clamping heads 202. At the same time, it can also pre-position the part to a certain extent, improving the efficiency and accuracy of clamping.

[0033] The pressure plate 300 includes: two movable slots 304, located on one side of the pressure plate 300; two adjusting plates 301, installed within the movable slots 304; a lead screw 305, installed within the movable slots 304 and connected to the adjusting plate 301 via a thread; and a knob 306, installed on the pressure plate 300, with one end of the lead screw 305 connected to the knob 306. The adjusting plate 301 includes: a pressure arm 302, installed at the bottom of the adjusting plate 301; and a pressure sensor 303, installed at the bottom of the pressure arm 302.

[0034] The aforementioned pressure plate 300 presses and fixes the product placed on the clamping seat 200, preventing displacement due to external forces during processing. An adjusting plate 301 is installed within the moving groove 304, with a sliding fit between the adjusting plate 301 and the moving groove 304, allowing for flexible movement within the groove. A lead screw 305 is installed within the moving groove 304, and is threadedly connected to the adjusting plate 301. When the lead screw 305 rotates, the adjusting plate 301 moves along the direction of the moving groove 304 under the influence of the lead screw 305. The operator can easily control the rotation of the lead screw 305 by manually rotating the knob 306, thereby achieving precise adjustment of the position of the adjusting plate 301 and enabling the fixing of products of different sizes.

[0035] The pressure arm 302 is made of high-strength spring steel, possessing excellent elasticity and toughness. A pressure sensor 303 is installed at the bottom of the pressure arm 302. This high-precision strain gauge pressure sensor 303 can accurately detect the pressure applied by the pressure arm 302 to the product in real time. When the pressure arm 302 presses down on the product under the action of the adjusting plate 301, the pressure sensor 303 transmits the detected pressure signal to the control system. The operator can then adjust the pressure of the pressure arm 302 on the product using the adjusting knob 306, ensuring that the product is secured without being damaged by excessive pressure.

[0036] It also includes: a fixture body 100, on which the clamping seat 200 is mounted; and a first power source 101, on which the first power source 101 is mounted, and the output shaft of the first power source 101 is connected to the pressure plate 300.

[0037] The first power source 101 uses an electric actuator, which has the advantages of large thrust and precise stroke control. When it is necessary to fix the product, the operator can start the first power source 101 through the control system. The output shaft of the electric actuator will extend and push the pressure plate 300 downward until the pressure arm 302 on the pressure plate 300 contacts the product and applies appropriate pressure, thus completing the product fixing operation.

[0038] During use, the fixture body 100 is installed on the laser engraving and welding worktable. The product to be processed is placed in the fixed inner groove 201 area on the top of the clamping seat 200. As the product is placed in, its shape simultaneously presses against the two clamping heads 202 located in the grooves 203 on both sides of the fixed inner groove 201. The clamping heads 202 are displaced after being pressed by the product. The displacement sensor 205 installed on the inner wall of the groove 203 detects this displacement change in real time and immediately transmits the signal to the controller. When the clamping heads 202 stop displacing, the controller controls the second power source 401 to turn on based on the received signal. The power shaft of the second power source 401 drives the positioning head 400 to move. The positioning head 400 fixes and supports the clamping head 202 in the groove 203, so that the clamping head 202 firmly fixes the product. The elastic element 204 deforms due to the movement of the clamping head 202 and stores elastic potential energy, which prepares for the subsequent reset of the clamping head 202. The inclined surfaces of the two clamping heads 202 approach each other at one end, which play a guiding role when the product is placed, helping the product to smoothly enter the predetermined position between the two clamping heads 202.

[0039] The operator starts the first power source 101 through the control system. The output shaft of the electric push rod extends and pushes the pressure plate 300 downward. The adjusting plate 301 in the two moving slots 304 on one side of the pressure plate 300 moves accordingly. The operator manually rotates the knob 306 installed on the pressure plate 300. The knob 306 drives the lead screw 305 to rotate. The lead screw 305 drives the adjusting plate 301 to move flexibly in the moving slot 304 through the threaded connection, thereby accurately adjusting the position of the pressure arm 302 so that the pressure arm 302 is accurately aligned with the part of the product that needs to be pressed.

[0040] The pressure arm 302 presses down on the product under the action of the adjusting plate 301. The high-precision strain gauge pressure sensor 303 installed at the bottom of the pressure arm 302 accurately detects the pressure applied to the product by the pressure arm 302 in real time and transmits the pressure signal to the control system. Based on this signal, the operator continues to rotate the knob 306 to adjust the screw 305, thereby changing the position of the adjusting plate 301 and precisely adjusting the pressure of the pressure arm 302 on the product to ensure that the product is firmly fixed without being damaged by excessive pressure.

[0041] After completing the above product fixing operations, start the five-axis laser engraving machine to process the product. Due to the precise positioning and fixing effect of this device, multi-face spot welding can be performed in one clamping, effectively reducing the number of processing clamps, reducing manpower requirements, and at the same time greatly improving the dimensional stability of the product, ensuring welding accuracy and consistency, and improving product quality.

[0042] In summary, compared with existing technologies, it has the following beneficial effects:

[0043] By having two clamping heads 202 work in conjunction with the pressure block, stable positioning and fixation can be achieved in one go. During the entire processing, there is no need to frequently change the processing clamping position, which reduces the time loss caused by clamping position switching and significantly improves processing efficiency.

[0044] The positioning head 400 fixes the clamping head 202 in the groove 203 to ensure stable and accurate clamping. The pressure sensor 303 monitors the pressure of the pressure arm 302 on the product in real time. The operator makes precise adjustments based on the signal to further ensure the product fixation effect.
