Description

Technical Field

[0001] The utility model relates to the technical field related to electric arc material-additive impact devices, and in particular to an electric arc material-additive impact device which is convenient for adjusting the force. Background Art

[0002] Arc additive manufacturing is a promising alternative to subtractive manufacturing. The mechanical properties of the materials produced by it are comparable to those of forged or cast materials with significant cost savings and high deposition rates. However, problems such as high residual stress and deformation will occur during the additive manufacturing process, so stress relief operations are required for the additive products.

[0003] According to the disclosure, an arc additive impact device (publication number: CN 217070746 U) includes an impact mechanism, which is connected to an upper driving mechanism to achieve up and down reciprocating motion. The impact mechanism at least includes a telescopic rod, which includes an inner rod and an outer rod that are sleeved and can slide relative to each other in a vertical direction. The lower end of the inner rod extends from the lower end of the outer rod and is fixed with an impact head. A limit portion extending radially outward is formed at the upper end of the outer rod. The portion of the inner rod extending to the outside of the outer rod is threadedly connected with an adjusting member. An elastic member is sleeved radially outward of the outer rod, one end of the elastic member abuts against the limit portion, and the other end abuts against the adjusting member. In the above application documents, the magnitude of the impact force applied can be adjusted accordingly according to different products, and different impact loads can be achieved to ensure the effect of stress removal. However, when using the device, the adjusting member needs to be rotated manually to complete the adjustment of the impact force, which makes it still inconvenient when used. Utility Model Content

[0004] The utility model aims to solve the problem that the existing technology needs to manually rotate the adjustment piece to adjust the impact force, which is still inconvenient to use. To this end, the utility model proposes an arc material-additive impact device that is easy to adjust the force and can automatically adjust the magnitude of the impact force.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an arc material-additive impact device that is easy to adjust the force, comprising a frame, a limit block is fixedly connected to the inner wall of the frame, a sleeve is slidably connected to the inner wall of the frame, a limit groove is provided on the outer wall of the sleeve, and the outer wall of the limit groove is slidably connected to the limit block, a damping shaft is fixedly connected to the inner wall of the frame, a servo motor is fixedly connected to the inner wall of the frame, a gear is fixedly connected to the outer wall of one end of the servo motor, and an adjustment component is mounted on the outer wall of the damping shaft;

[0006] The adjustment component includes a telescopic tube, which is installed on the surface of the damping shaft. A sliding groove is provided on the outer wall of the telescopic tube, a groove is provided on the outer wall of the telescopic tube, a pawl is rotatably connected to the inner wall of the groove, a spring sheet is fixedly connected to the inner wall of the groove, a clamping block is fixedly connected to the inner wall of the sleeve, and the clamping block is slidably connected to the sliding groove.

[0007] Preferably, the grooves are arranged in multiple groups on the outer wall of the telescopic tube, and the pawl is rotatably connected to the grooves via a spring sheet, so that when the pawl is not subjected to force, the spring sheet can push the pawl to reset.

[0008] Preferably, the sleeve is rotatably connected to the limit block via a limit groove, and the limit blocks are arranged in multiple groups on the inner wall of the frame and symmetrically arranged with respect to the central axis of the frame. The sleeve is limited by the sliding connection between the limit block and the limit groove to prevent the sleeve from rotating inside the frame.

[0009] Preferably, an impact assembly is assembled on the outer wall of one end of the servo motor, and the impact assembly includes a cam, which is installed on the surface of the servo motor, a connecting ring is rotatably connected to the outer wall of the cam, a ball is rotatably connected to the inner wall of the connecting ring, a rotating block is fixedly connected to the outer wall of the connecting ring, an impact block is fixedly connected to the outer wall of the rotating block, an impact head is slidably connected to the inner wall of the sleeve, and a spring is fixedly connected to the outer wall of the impact head.

[0010] Preferably, the balls are arranged in multiple groups on the inner wall of the connecting ring and are symmetrically arranged with respect to the central axis of the connecting ring. The balls can reduce the friction between the connecting ring and the cam, so that the connecting ring remains stable when the cam rotates.

[0011] Preferably, the impact head forms a telescopic structure through a spring and a sleeve, so that when the impact head is not subjected to force, the spring can push the impact head to reset.

[0012] The difference from the prior art is that the beneficial effects of this application are:

[0013] (1) The arc additive impact device that is easy to adjust the force, through the mutual cooperation of the gear and the adjustment component, makes it possible for the gear to not push the telescopic tube to rotate when rotating clockwise, but to push the sleeve to make up and down reciprocating motion inside the frame according to the path of the slide groove when rotating counterclockwise, so that the distance between the impact block and the impact head can be adjusted. The closer the distance, the greater the impact force, and the farther the distance, the smaller the impact force, thereby completing the adjustment of the impact force and improving the overall ease of use of the device.

[0014] (2) The arc additive impact device, which is easy to adjust the force, cooperates with the servo motor and the impact assembly. The servo motor drives the rotation of the cam, so that the impact block moves up and down inside the frame and hits the upper end of the impact head, so that the impact head impacts the product. When the impact block moves upward, the impact head is reset upward under the action of the spring, and then impacts the product again after being reset. This is repeated many times to complete the impact operation and remove stress, thereby improving the overall usability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Embodiment 1

[0034] See also Figure 1 - Figure 8 As shown in the figure, an arc additive impact device that is easy to adjust the force includes a frame 100, a limit block 200 is fixedly connected to the inner wall of the frame 100, a sleeve 300 is slidably connected to the inner wall of the frame 100, a limit groove 400 is provided on the outer wall of the sleeve 300, and the outer wall of the limit groove 400 is slidably connected to the limit block 200, a damping shaft 500 is fixedly connected to the inner wall of the frame 100, a servo motor 600 is fixedly connected to the inner wall of the frame 100, a gear 700 is fixedly connected to the outer wall of one end of the servo motor 600, and an adjustment component 800 is mounted on the outer wall of the damping shaft 500;

[0035] The adjustment assembly 800 includes a telescopic tube 801, which is mounted on the surface of the damping shaft 500. A sliding groove 802 is provided on the outer wall of the telescopic tube 801, and a groove 803 is provided on the outer wall of the telescopic tube 801. A ratchet 804 is rotatably connected to the inner wall of the groove 803. When the gear 700 rotates counterclockwise, the ratchet 804 is pushed to squeeze the surface of the groove 803, thereby pushing the telescopic tube 801 to rotate on the surface of the damping shaft 500. A spring sheet 805 is fixedly connected to the inner wall of the groove 803. When the gear 700 rotates clockwise, the ratchet 804 is pushed to rotate inside the groove 803 and exerts pressure on the spring sheet 805. When the gear 700 is separated from the surface of the ratchet 804, the spring sheet 805 is forced to push the ratchet 804 to reset. A block 806 is fixedly connected to the inner wall of the sleeve 300, and the block 806 is slidably connected to the slide groove 802. Through the sliding connection between the slide groove 802 and the block 806, the sleeve 300 can be pushed to reciprocate up and down inside the frame 100 according to the path of the slide groove 802, so that the distance between the impact block 905 and the impact head 906 can be adjusted. The closer the distance, the greater the impact force, and the farther the distance, the smaller the impact force, thereby completing the adjustment of the impact force and improving the overall usability of the device.

[0036] When in use, when the gear 700 rotates clockwise, it will push the pawl 804 to rotate inside the groove 803 and apply pressure to the spring sheet 805. When the gear 700 is separated from the surface of the pawl 804, the spring sheet 805 is forced to push the pawl 804 to reset. When the punching force needs to be adjusted, the servo motor 600 is controlled to drive the gear 700 to rotate counterclockwise. When the gear 700 rotates counterclockwise, it will push the pawl 804 to squeeze the surface of the groove 803, thereby pushing the telescopic tube 801 to rotate on the surface of the damping shaft 500. When the telescopic tube 801 rotates, it can push the sleeve 300 to reciprocate up and down inside the frame 100 according to the path of the slide groove 802 through the sliding connection between the slide groove 802 and the card block 806, so that the distance between the impact block 905 and the impact head 906 can be adjusted. The closer the distance, the greater the impact force, and the farther the distance, the smaller the impact force, thereby completing the adjustment of the impact force, thereby improving the overall ease of use of the device.

[0037] See also Figure 1 - Figure 8 As shown in the figure, an impact assembly 900 is mounted on the outer wall of one end of the servo motor 600. The impact assembly 900 includes a cam 901. The cam 901 is mounted on the surface of the servo motor 600. A connecting ring 902 is rotatably connected to the outer wall of the cam 901. A ball 903 is rotatably connected to the inner wall of the connecting ring 902. The ball 903 can reduce the friction between the connecting ring 902 and the cam 901, so that the connecting ring 902 can maintain its own stability when the cam 901 rotates. A rotating block 904 is fixedly connected to the outer wall of the connecting ring 902. An impact block 905 is fixedly connected to the outer wall of the rotating block 904. When the connecting ring 902 swings, the impact block 905 can be driven by the rotating block 904 to make up and down reciprocating motion inside the frame 100. An impact head 906 is slidably connected to the inner wall of the sleeve 300, and a spring 907 is fixedly connected to the outer wall of the impact head 906. When the impact block 905 moves upward, the impact head 906 is reset upward under the action of the spring 907, and then impacts the product again after being reset. This is repeated many times to complete the impact operation and remove stress, thereby improving the overall usability of the device.

[0038] When in use, start the servo motor 600 to drive the cam 901 to rotate, and the ball 903 is connected to the cam 901 through rotation, so that the connecting ring 902 will not rotate when the cam 901 rotates, but will only swing up and down according to the connecting groove on the surface of the cam 901, and drive the impact block 905 to reciprocate up and down inside the frame 100 through the rotating block 904. When the impact block 905 moves downward, it hits the upper end of the impact head 906, thereby pushing the impact head 906 to impact downward and squeeze the spring 907 to shrink downward. After the impact head 906 impacts the product, energy is transferred to the molded product to eliminate internal stress. When the impact block 905 moves upward, the impact head 906 is reset upward under the action of the spring 907, and then impacts the product again after resetting. This is repeated many times to complete the impact operation and remove stress, thereby improving the overall ease of use of the device.
