Description

Technical Field

[0002] In modern manufacturing, stamping is an important process widely used in the forming of various metal and non-metal materials. For example, in the fields of automotive parts manufacturing, electronic equipment housing production, and hardware processing, stamping technology plays an indispensable role due to its high efficiency and precision. The stamping process requires that the workpiece to be processed must be precisely positioned within the working area of the stamping equipment during the processing to ensure the accuracy and stability of the stamping operation. Traditional stamping clamping and positioning methods often have many defects. In many traditional stamping equipment, clamping and positioning operations mostly rely on manual labor or relatively simple mechanical structures. Manual clamping and positioning is not only inefficient, but also easily affected by the operator's skill level and fatigue level, resulting in problems such as inaccurate clamping and positioning and uneven clamping force. This inaccuracy and unevenness will cause displacement of the workpiece during the stamping process, thereby affecting the quality and dimensional accuracy of the product. At the same time, traditional clamping and positioning methods have poor adaptability when facing workpieces of different sizes and shapes, and often require a lot of time to adjust or replace the clamping mold, which seriously affects the continuity of production, increases production costs, and is not conducive to large-scale, high-efficiency industrial production.

When the device is used, the workpiece to be punched is placed above the punching table, and the motor is controlled to drive the support screw to rotate above the support plate. During the rotation of the support screw, the linkage block moves downward under the action of its thread, and the linkage rod rotates at one end of the linkage block and moves downward with the linkage block. During the movement of the linkage block, the other end of the linkage rod will pull the first support rod to rotate around the connection point between it and the support block.

[0014] The technical solution of the present application will be further described in detail below in conjunction with specific implementation methods.

[0015] like Figure 1-8 As shown, the present invention provides a technical solution: an automatic hydraulic device that is convenient for clamping and positioning, comprising a base 1, a placing table 2 is fixedly connected to the top of the base 1, a supporting bracket 3 is fixedly installed under the placing table 2, and a supporting plate 4 is fixedly connected between the inner walls of the supporting bracket 3. Through the cooperation of the supporting bracket 3 and the supporting plate 4, the supporting bracket 3 provides an installation position for the supporting plate 4 and shares the pressure when the device is running. The supporting plate 4 serves as the installation base of the clamping mechanism 5, so that the clamping mechanism 5 can work stably. During the operation of the entire device, the presence of the supporting bracket 3 and the supporting plate 4 ensures the stability of the clamping mechanism 5, thereby ensuring the clamping effect of the workpiece. The supporting bracket 3 is fixedly installed with the clamping mechanism 5 through the supporting plate 4. The clamping mechanism 5 includes a support block 501, and the number of the support blocks 501 is four. The four support blocks 501 are respectively fixedly installed at the four equal points of the support plate 4. Such a layout makes the support of the clamp 504 more balanced. When clamping the workpiece, force can be evenly applied from multiple directions to ensure that the workpiece is stably fixed in the center position of the stamping table 7, thereby improving the accuracy of clamping. The upper part of the support block 501 is rotatably connected to a first support rod 502, and the upper part of the support block 501 is rotatably connected to a second support rod 503 located on one side of the first support rod 502. The other ends of the first support rod 502 and the second support rod 503 are rotatably connected to a clamp 504. Through the cooperation of the first support rod 502 and the second support rod 503, the first support rod 502 and the second support rod 503 are rotatably connected to the clamp 504 and the support block 501 respectively, thereby increasing the flexibility of the movement of the clamp 504. In the process of the clamp 504 moving toward the center of the stamping table 7 and clamping the workpiece, this connection structure can better adapt to workpieces of different shapes and sizes, and the clamp 504 can be adaptively adjusted according to the contour of the workpiece. , ensuring that it fits tightly against the surface of the workpiece for clamping, the center position of the support plate 4 is rotatably connected to the support screw 505, and the outer wall of the support screw 505 is threadedly connected to the linkage block 506, and the linkage block 506 is designed in a well shape. The four sides of the linkage block 506 are rotatably connected to four linkage rods 507. Through the cooperation between the linkage block 506 and the linkage rod 507, the threaded connection between the support screw 505 and the linkage block 506, and the rotation connection between the linkage block 506, the linkage rod 507 and the first support rod 502, an efficient transmission system is formed. When the support screw 505 rotates, the vertical movement of the linkage block 506 can be accurately converted into the opening and closing action of the clamp 504, thereby improving the efficiency and accuracy of clamping; The other ends of the four linkage rods 507 are rotatably connected to the middle parts of the four first support rods 502 respectively. A control motor 6 is provided under the support plate 4. Due to the provision of the control motor 6, the opening and closing of the clamp 504 can be conveniently controlled by controlling the forward and reverse rotation of the motor 6, thereby reducing the workload of manual operation and possible errors. In the process of large-scale production, the automated control of the clamp 504 can improve production efficiency and ensure the consistent clamping effect of each workpiece. The control motor 6 is fixedly mounted above the support bracket 3, and the output end of the control motor 6 is connected to one end of the support screw 505. A stamping table 7 is fixedly mounted at the center position above the placement table 2. Four slide slots 8 are respectively provided on the four sides of the stamping table 7 above the placement table 2, and the four clamps 504 pass through the four slide slots 8 respectively. Four pillars 9 are fixedly installed at the four corners of the placement table 2, and the tops of the four pillars 9 are fixedly connected to a top plate 10. A hydraulic rod 11 is fixedly installed above the top plate 10, and the end of the hydraulic rod 11 passes through the top plate 10. The end of the hydraulic rod 11 is fixedly connected to a stamping plate 12. The four pillars 9 pass through the four corners of the stamping plate 12 respectively. This design guides and limits the stamping plate 12, ensuring that the stamping plate 12 remains vertical and stable during the up and down movement. A stamping block 13 is fixedly installed at the center position of the stamping plate 12 below. The position of the stamping block 13 corresponds to the position of the placement table 2. This corresponding design enables the stamping block 13 to directly act on the workpiece placed on the placement table 2, thereby ensuring the accuracy and effectiveness of the stamping operation and improving the quality of the stamping operation. One side of the base 1 is fixedly connected to a mounting bracket 14, and the mounting bracket 14 is a Y-shaped design. A sensor 15 is fixedly installed on one side of the mounting bracket 14. Because the sensor 15 is provided, the sensor 15 can detect the size of the workpiece, and provide a basis for adjusting the distance between the two unloading mechanisms 18, so that the entire unloading process can be intelligently controlled according to the actual situation of the workpiece, thereby improving the degree of automation and working efficiency of the device. A guide plate 19 is fixedly installed on the side of the placement table 2 opposite to the mounting bracket 14. The guide plate 19 is an inclined design. Because the guide plate 19 is provided, the inclined guide plate 19 provides a guiding effect for the unloading of the workpiece. The stamped workpiece can be smoothly moved to the outside of the placement table 2 along the inclined surface of the push plate 1803 and the guide plate 19, which is convenient for collecting and subsequently processing the processed workpiece, thereby improving the consistency of the work flow of the entire device. The top of the mounting bracket 14 is fixedly connected with an electric push rod 16, and the end of the electric push rod 16 is fixedly connected with an adjusting mechanism 17. Due to the provision of the adjusting mechanism 17, the two-way screw 1702 rotates to drive the two adjusting sliders 1704 on the outer wall to move closer or farther away from each other, thereby adjusting the distance between the two blanking mechanisms 18. When processing workpieces of different sizes, the distance between the blanking mechanisms 18 can be adjusted quickly and accurately, thereby improving the adaptability of the device. The adjusting mechanism 17 includes a fixed bracket 1701, and a two-way screw 1702 is rotatably connected between the inner walls of the fixed bracket 1701. One end of the fixed bracket 1701 is fixedly mounted with a driving electric push rod 16. Machine 1703, the output end of the driving motor 1703 is connected to one end of the bidirectional screw 1702, the outer wall of the bidirectional screw 1702 is symmetrically threaded with two adjusting sliders 1704, and a limiting rod 1705 is fixedly installed between the inner walls of the fixed bracket 1701 on one side of the bidirectional screw 1702. Due to the provision of the limiting rod 1705, the existence of the limiting rod 1705 can ensure the linear motion of the adjusting slider 1704 and prevent the adjusting slider 1704 from rotating during the rotation of the bidirectional screw 1702, thereby ensuring the accuracy of the spacing adjustment of the blanking mechanism 18. The limiting rod 1705 passes through the two adjusting sliders 1704; One end of the two adjusting sliders 1704 is fixedly connected to two blanking mechanisms 18, and the blanking mechanism 18 includes an L-shaped bracket 1801, and the end of the L-shaped bracket 1801 is fixedly connected to a protrusion 1802, and the protrusion 1802 is rotatably connected to a push plate 1803 through a pin shaft. A telescopic rod 1804 is provided between the L-shaped bracket 1801 and the push plate 1803. Because of the provision of the telescopic rod 1804, when the telescopic rod 1804 is extended, it rotates above the L-shaped bracket 1801 through one of the connecting blocks 1805 and pushes the push plate 1803 through the other connecting block 1805, so that the push plate 1803 rotates, ensuring that the push plate 1803 can smoothly push the workpiece down, thereby improving the reliability of blanking. The two ends of the telescopic rod 1804 are rotatably connected to two connecting blocks 1805, one of which is connected to the bottom of the push plate 1803, and the other is connected to the top of the L-shaped bracket 1801.

[0016] The working principle of the present invention is as follows: when using the device, the workpiece is first placed above the stamping table 7, and the control motor 6 drives the support screw 505 to rotate above the support plate 4, and the linkage block 506 is moved downward in the vertical direction by the action of the thread. During the movement, the linkage block 506 pulls the first support rod 502 through the linkage rod 507, and the first support rod 502 is pulled to rotate above the support block 501. During this process, the grabbing clamp 504 begins to approach the center position of the stamping table 7 under the drive of the first support rod 502. At the same time, under the traction of the first support rod 502, the end of the grabbing clamp 504 itself will gather inward with the end of the second support rod 503 as the axis, so that the end of the grabbing clamp 504 gradually moves inward, and the four grabbing clamps 504 clamp the workpiece at the same time, thereby fixing the workpiece in the center position of the stamping table 7. After the workpiece is fixed, the hydraulic rod 11 drives the stamping plate 12 and the stamping block 13 to press down, and the stamping block 13 performs hydraulic processing on the workpiece under the action of the hydraulic rod 11; After the hydraulic rod 11 is completed, the control motor 6 drives the support screw 505 to rotate in the opposite direction, so that the linkage block 506 moves upward in the vertical direction. The linkage block 506 pushes the first support rod 502 through the linkage rod 507 to open the clamp 504. During the continuous upward movement of the linkage block 506, the linkage rod 507 continuously pushes the first support rod 502 to rotate above the support block 501, thereby moving the four clamps 504 into the slide 8. At this time, the workpiece is above the punching table 7, and the sensor 15 detects the size of the workpiece and transmits the signal to the drive motor 1703. The drive motor 1703 controls the rotation of the bidirectional screw 1702, and the two adjusting sliders 1704 drive the two blanking mechanisms 18 to approach each other. Since there is no thread at the center position of the bidirectional screw 1702, the distance between the two blanking mechanisms 18 will not be less than the punching table 7. The two blanking mechanisms After the mechanism 18 is adjusted to the appropriate spacing according to the size of the workpiece, the electric push rod 16 extends and drives the adjusting mechanism 17 to move in the direction of the guide plate 19. During the movement of the adjusting mechanism 17, the workpiece above the stamping table 7 is pushed by the L-shaped bracket 1801 and will fall above the push plate 1803. When the electric push rod 16 extends to a certain position, the telescopic rod 1804 extends and rotates above the L-shaped bracket 1801 through one of the connecting blocks 1805 and pushes the push plate 1803 through the other connecting block 1805, so that the push plate 1803 rotates through the protrusion 1802 above the L-shaped bracket 1801. The two push plates 1803 rotate synchronously and push down the workpiece stamped above them. The workpiece moves along the inclined surface of the push plate 1803 and the guide plate 19 to the outside of the placement table 2, and the processed workpiece is collected from the guide plate 19 for use.
