Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, specifically a clamping device for manufacturing mechanical equipment with high stability. Background Technology

[0002] In the field of mechanical equipment manufacturing, clamping devices are key auxiliary equipment for positioning and fixing workpieces. Their performance directly affects the product processing accuracy, production efficiency and operational safety. As modern manufacturing develops towards high precision, integration and automation, higher requirements are placed on the stability, adaptability and adjustment flexibility of clamping devices. Especially in welding processes involving workpieces, clamping devices need to simultaneously meet the requirements of synchronous fixing, position holding and posture adjustment of multiple workpieces to ensure the assembly accuracy and welding quality of welded joints.

[0003] In existing technologies, clamping devices for workpiece welding mostly adopt fixed structures, focusing on the stable clamping of a single workpiece. For example, radial clamping of the workpiece is achieved through symmetrical grippers driven by hydraulic or pneumatic forces. Moreover, they are mostly integrated linkage designs, making it difficult to independently fine-tune the relative positions of the two workpieces according to welding requirements after clamping. When insufficient alignment accuracy of the joint is found during the welding process, the entire clamping mechanism needs to be loosened for repositioning, which is cumbersome and prone to secondary clamping errors of the workpiece. Therefore, we need to propose a clamping device for mechanical equipment manufacturing with high stability. Utility Model Content

[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution:

[0022] A highly stable clamping device for manufacturing mechanical equipment includes: a base plate 1, on which two sets of U-shaped frames 2 are symmetrically arranged on top. Two sets of guide electric cylinders 3 are fixedly connected to the top of the U-shaped frames 2. Positioning frames 4 are fixedly connected to the top of the telescopic ends of the two sets of guide electric cylinders 3. A clamping component 5 for positioning the workpiece is provided on the positioning frame 4. By setting the base plate 1 as a basic support, the U-shaped frames 2 provide an installation carrier, the guide electric cylinders 3 realize the lifting and lowering of the positioning frame 4, and the clamping component 5 is responsible for positioning the workpiece, the device achieves the effect of coordinated work of all components and provides a stable structural foundation for workpiece clamping. The base plate 1 is made of high-strength cast iron and is subjected to aging treatment to eliminate internal stress, ensuring that it is not easily deformed during long-term use. The U-shaped frames 2 and the base plate 1 are fastened together by bolts, and anti-slip pads are added to the connection parts to further improve the overall structural stability.

[0023] A fixed housing 6 is fixedly connected to the bottom of the base plate 1. The fixed housing 6 contains a power component 7 for adjusting the distance between the two sets of C-shaped frames 2. By setting the fixed housing 6 to protect and position the power component 7, the power component 7 drives the C-shaped frames 2 to adjust the spacing, thus ensuring stable power transmission and enabling the device to adapt to different workpiece spacing requirements. The fixed housing 6 is made of welded steel plate with a rust-proof coating on the surface, which can effectively prevent the internal power component 7 from being corroded by external dust and moisture, extending the service life of the device. In addition, the fixed housing 6 is fixed to the base plate 1 by welding, with high connection strength, and can withstand the vibration generated by the power component during operation.

[0024] The clamping assembly 5 includes an electric push rod 501, which is fixedly installed on the top of the positioning frame 4. The bottom end of the telescopic end of the electric push rod 501 passes through the positioning frame 4 and is fixedly connected to a pressure block 502. By setting the electric push rod 501 to provide driving force, the pressure block 502 is driven to move up and down, achieving flexible control of the pressure block 502 on the workpiece, ensuring reliable workpiece clamping. The electric push rod 501 is a high-precision servo electric push rod, whose telescopic stroke can be precisely controlled with a minimum control accuracy of 0.1mm. The pressure block 502 is made of alloy steel, and the surface is quenched, resulting in high hardness and good wear resistance. It is rigidly connected to the telescopic end of the electric push rod 501 through a flange to ensure lossless power transmission.

[0025] It also includes two sets of guide rods 503. The bottom ends of both sets of guide rods 503 are fixedly connected to the top of the pressure block 502, and both sets of guide rods 503 are slidably connected to the positioning frame 4. By setting the guide rods 503 to slide with the positioning frame 4, the movement of the pressure block 502 is guided, which prevents the pressure block 502 from deviating during movement and ensures accurate pressing position. The guide rods 503 are made of chrome-plated round steel with high surface smoothness. The gap between the guide rods 503 and the guide holes on the positioning frame 4 is controlled between 0.02-0.05mm, which can ensure smooth sliding and effectively limit the radial displacement of the pressure block 502. The two sets of guide rods 503 are symmetrically distributed on both sides of the electric push rod 501, so that the pressure block 502 is subjected to balanced force.

[0026] The bottom of the clamping block 502 is provided with a V-groove 8. The workpiece to be clamped and positioned is placed on the positioning frame 4 and located below the V-groove 8. By setting the V-groove 8 to contact the workpiece, the self-centering characteristic of the V-shaped structure is utilized to achieve stable clamping of cylindrical workpieces of different diameters, thereby improving the device's adaptability to workpiece shapes. The inner wall of the V-groove 8 is attached with a rubber buffer pad. The surface of the buffer pad is provided with anti-slip texture, which can not only prevent the workpiece from being pinched, but also increase the friction between the buffer pad and the workpiece, preventing the workpiece from slipping during processing. The included angle of the V-groove 8 is designed to be 90 degrees, which can be used to accommodate cylindrical workpieces with diameters ranging from 10 to 200 mm.

[0027] The power assembly 7 includes a bidirectional screw 701, with both ends of the bidirectional screw 701 rotatably mounted on the inner walls of the two sides of the fixed housing 6. One end of the bidirectional screw 701 passes through the fixed housing 6 and is connected to a drive motor 702. Two sets of moving plates 703 are symmetrically connected to the outer wall of the bidirectional screw 701 via threaded sleeves. Both ends of the two sets of moving plates 703 pass through the fixed housing 6 and are fixedly connected to the mortise frame 2. By setting the drive motor 702 to drive the bidirectional screw 701 to rotate, the two sets of moving plates 703 drive the mortise frame 2 to move synchronously in opposite directions, achieving precise adjustment of the distance between the two sets of mortise frames 2 to adapt to the clamping effect of workpieces of different specifications. The bidirectional screw 701 is made of high-strength alloy structural steel, and its surface is precision ground and threaded, with a pitch accuracy of 0.01mm. The threaded sleeve and the moving plate 703 are fixed by welding to ensure that there is no relative slippage during transmission.

[0028] Guide grooves 9 adapted to the movable plate 703 are respectively provided on the two side walls of the fixed shell 6. The movable plate 703 is slidably connected to the guide grooves 9. By setting the guide grooves 9, the movement of the movable plate 703 is limited and guided, so as to ensure the smooth movement of the movable plate 703 and thus ensure the precise adjustment of the spacing of the frame 2. The inner wall of the guide groove 9 is equipped with a wear-resistant slider. The slider is made of polytetrafluoroethylene, which has a low coefficient of friction and high wear resistance, and can reduce the frictional resistance between the movable plate 703 and the guide groove 9. At the same time, the length of the guide groove 9 is designed according to the maximum adjustment spacing of the device to ensure that the movable plate 703 has sufficient movement stroke.

[0029] The drive motor 702 is fixedly installed on one side wall of the fixed housing 6. One end of the output shaft of the drive motor 702 is fixedly connected to one end of the bidirectional screw 701, and the drive motor 702 is set as a geared motor. By setting the geared motor as the drive source, the speed is reduced and the torque is increased, which achieves the effect of ensuring the stable rotation of the bidirectional screw 701 and making the adjustment process of the spacing of the C-shaped frame 2 smooth and controllable. The drive motor 702 is equipped with an encoder, which can provide real-time feedback on the motor speed and rotation angle, and realize precise control of the rotation amount of the bidirectional screw 701. The motor and the fixed housing 6 are connected by a shock-absorbing pad to reduce the impact of the vibration generated by the motor during operation on the overall stability of the device.

[0030] Working principle: First, based on the length and specifications of the workpiece to be processed, start the drive motor 702. The output shaft of the drive motor 702 drives the bidirectional screw 701 to rotate within the fixed housing 6. Since the threads at both ends of the bidirectional screw 701 are in opposite directions, the two sets of screw sleeves will drive the moving plate 703 to move in opposite directions under the guidance of the guide groove 9, thereby driving the two sets of mortise and tenon frames 2 to move synchronously in opposite directions. After adjusting the distance between the two sets of mortise and tenon frames 2 to a position suitable for the workpiece, turn off the drive motor 702. Then, place the workpiece on the positioning frame 4, positioning it directly below the V-groove 8 at the bottom of the pressure block 502. Based on the height of the workpiece, start the guide electric cylinder 3. The telescopic end of the guide electric cylinder 3... The moving positioning frame 4 and the clamping assembly 5 move up and down to adjust the clamping block 502 to a suitable height position. Then, the electric push rod 501 is activated, and the telescopic end of the electric push rod 501 extends downward, driving the clamping block 502 to move down. Under the guidance of the guide rod 503, the clamping block 502 moves smoothly until the V-groove 8 is in close contact with the workpiece surface. The electric push rod 501 applies appropriate pressure to clamp and fix the workpiece. At this time, the operation of the electric push rod 501 can be stopped, and the clamping and positioning of the workpiece is completed, so as to carry out subsequent welding, processing and other operations. When it is necessary to remove the workpiece, the electric push rod 501 is activated in reverse, driving the clamping block 502 to move upward and detach from the workpiece, so that the workpiece can be taken out.
