Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, specifically to a clamping device for detecting spring clips. Background Technology

[0002] Stainless steel springs are a type of elastic element widely used in the machinery and electronics industries. When subjected to load, stainless steel springs can produce large elastic deformation, converting mechanical energy or kinetic energy into deformation energy. After unloading, the deformation of the spring disappears and returns to its original shape, converting deformation energy back into mechanical energy or kinetic energy.

[0003] Chinese Patent Announcement No. CN221882969U provides a spring clip testing clamping device and a spring clip detector. This patent makes it easier to hold the spring clip for measurement by setting a first push rod and a second push rod, and the up and down directions can be reversed to measure the spring clip in two directions.

[0004] In the aforementioned device, measuring the spring in different directions requires manual inversion by the operator, resulting in slow measurement speed, low efficiency, and reduced functionality of the device.

[0005] Based on this, the present invention designs a clamping device for detecting spring fragments to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a clamping device for detecting spring fragments.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A clamping device for detecting shrapnel includes a base, an L-shaped limiting frame fixedly mounted on the upper left side of the base, a hydraulic cylinder fixedly embedded in the front end of the L-shaped limiting frame, and a detection rod fixedly mounted on the output end of the hydraulic cylinder. The device also includes: A flipping mechanism is installed at the lower end of the L-shaped limiting frame; A clamping mechanism is installed on the right side of a flipping mechanism. The flipping mechanism is used to control the clamping mechanism to flip and to limit the movement of the spring to be tested. A rectangular groove is provided in the middle of the upper end of the base. An elastic support pad is fixedly installed at the bottom of the rectangular groove. A support base is fixedly installed at the upper end of the elastic support pad. The front and rear ends of the upper end of the support base are designed with rounded corners. The flipping mechanism includes a bearing and a limiting plate. The bearing is fixedly installed on the lower right side of the L-shaped limiting frame. The limiting plate is fixedly installed inside the bearing. An mounting plate is fixedly installed on the middle right side of the limiting plate. A servo motor is fixedly installed on the lower left side of the L-shaped limiting frame. The output shaft of the servo motor passes through the L-shaped limiting frame and is rotatably connected to the L-shaped limiting frame. The output end of the servo motor is fixedly connected to the limiting plate.

[0008] In one embodiment, the clamping mechanism includes a lower half-cylinder and an upper half-cylinder, the lower half-cylinder being located below the upper half-cylinder, an internally threaded connecting pipe being fixedly installed at the upper end of the lower half-cylinder, the diameter of the internally threaded connecting pipe being smaller than the diameter of the lower half-cylinder, and an externally threaded connecting pipe being fixedly installed at the lower end of the upper half-cylinder, the externally threaded connecting pipe and the internally threaded connecting pipe being threadedly connected.

[0009] In one embodiment, a mounting hole is provided on the right side of the mounting plate, and the internally threaded connecting pipe is inserted into the mounting hole. The diameter of the internally threaded connecting pipe is adapted to the inner diameter of the mounting hole, and the bottom of the lower cylinder abuts against the top of the support base.

[0010] In one embodiment, a first limiting ring is fixedly installed in the middle of the inner side of the internally threaded connecting pipe, and a second limiting ring is fixedly installed at the lower end of the inner side of the externally threaded connecting pipe.

[0011] In one embodiment, an insertion hole is provided in the middle of the right side of the lower half-cylinder, and a deformation monitoring component is installed inside the lower half-cylinder. The deformation monitoring component is used to provide feedback when deformation occurs during the detection of the spring. The deformation monitoring component includes an L-shaped abutment rod and a spring. The L-shaped abutment rod is installed in the insertion hole by a rotatable connection, and the top of the L-shaped abutment rod is located on the right side of the lower end of the first limiting ring. The spring is installed at the lower end of the L-shaped abutment rod by a fixed connection, and the end of the spring away from the L-shaped abutment rod is fixedly connected to the inner rear wall of the lower half-cylinder. A support plate is fixedly installed in the middle of the rear end of the lower half-cylinder, and the top of the support plate abuts against the bottom of the L-shaped abutment rod.

[0012] Beneficial effects (1) This solution uses the collaborative design of the flipping mechanism and the servo motor. After the servo motor is powered on, it can drive the limit plate to rotate precisely in the bearing. The mounting plate drives the clamping mechanism and the spring to rotate automatically without manual intervention. This not only greatly shortens the time for spring to turn and measure, but also improves the overall measurement speed and detection efficiency, and significantly enhances the automation functionality of the device.

[0013] (2) In this scheme, the elastic support pad in the rectangular groove of the base can buffer the impact force of the test. The rounded corner design at the top of the support seat can avoid scratching the spring. At the same time, the bottom of the lower cylinder abuts against the support seat, and the L-shaped limit frame limits the load of the hydraulic cylinder and the flipping mechanism, together creating a stable testing environment. In addition, the clamping mechanism can firmly fix the spring through the threaded connection of the internal threaded connecting pipe and the external threaded connecting pipe, combined with the double limit of the first limit ring and the second limit ring, to avoid the spring from shifting during the test. This not only ensures the accuracy of the test data, but also reduces the risk of damage to the spring due to improper operation.

[0014] (3) In this solution, when the spring is deformed during the test, it will squeeze the L-shaped abutment rod and compress the spring. The displacement change of the L-shaped abutment rod can provide real-time feedback on the deformation of the spring. The support plate ensures that the L-shaped abutment rod is always in a stable working state. This function can help the staff to find unqualified springs in time and prevent them from flowing into the subsequent process, thereby further improving the quality control capability of the test operation.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] In one embodiment, please refer to the appendix to the specification. Figure 1-5 A clamping device for detecting shrapnel includes a base 1, an L-shaped limiting frame 4 fixedly installed on the upper left side of the base 1, a hydraulic cylinder 5 fixedly embedded in the front end of the L-shaped limiting frame 4, and a detection rod 6 fixedly installed at the output end of the hydraulic cylinder 5. The device also includes: The flipping mechanism 7 is installed at the lower end of the L-shaped limit frame 4; The clamping mechanism 8 is installed on the right side of the flipping mechanism 7. The flipping mechanism 7 is used to control the flipping of the clamping mechanism 8, and the clamping mechanism 8 is used to limit the movement of the spring to be tested. A rectangular groove 11 is provided in the middle of the upper end of the base 1. An elastic support pad 2 is fixedly installed at the bottom of the rectangular groove 11. A support seat 3 is fixedly installed on the upper end of the elastic support pad 2. The front and rear ends of the upper end of the support seat 3 are designed with rounded corners. The flipping mechanism 7 includes a bearing 71 and a limiting plate 72. The bearing 71 is fixedly installed on the lower right side of the L-shaped limiting frame 4. The limiting plate 72 is fixedly installed inside the bearing 71. An mounting plate 74 is fixedly installed on the middle right side of the limiting plate 72. A servo motor 73 is fixedly installed on the lower left side of the L-shaped limiting frame 4. The output shaft of the servo motor 73 passes through the L-shaped limiting frame 4 and is rotatably connected to the L-shaped limiting frame 4. The output end of the servo motor 73 is fixedly connected to the limiting plate 72.

[0021] In this embodiment of the invention, when the device is in operation, the piece to be tested is first placed on the upper end of the support base 3, and the clamping mechanism 8 is used to limit and fix the piece to be tested. The elastic support pad 2 at the bottom of the support base 3 provides buffer protection. When it is necessary to test the piece in different directions, the flipping mechanism 7 in the electrical structure is activated. Its power source is an electrically driven component, which drives the clamping mechanism 8 to flip, eliminating the need for manual flipping of the piece. After flipping into place, the hydraulic cylinder 5 in the electrical structure is powered on, and the output end of the hydraulic cylinder 5 pushes the detection rod 6 to move towards the piece, thus completing the detection operation of the piece. The rectangular groove 11 at the upper end of the base 1 provides a stable installation space for the support base 3, and the L-shaped limiting frame 4 provides a firm bearing and limiting function for the hydraulic cylinder 5 and the flipping mechanism 7, ensuring the stable operation of each component throughout the entire testing process.

[0022] In one embodiment of this utility model, the cooperation between the flipping mechanism 7 and the clamping mechanism 8 replaces the manual operation of inverting the spring, greatly improving the measurement speed and detection efficiency of the spring, effectively enhancing the functionality of the device, and solving the problem of low efficiency caused by manual operation in the prior art.

[0023] The L-shaped limit frame 4 achieves precise limit installation of the hydraulic cylinder 5 and the tilting mechanism 7, ensuring the stability of the detection path of the detection rod 6, improving the accuracy of the spring detection data, and at the same time, the overall structure is compact, which improves the stability and reliability of the device operation.

[0024] In one embodiment, such as Figure 1-5 As shown, this is a preferred embodiment of the present invention: The clamping mechanism 8 includes a lower half-cylinder 81 and an upper half-cylinder 82. The lower half-cylinder 81 is located below the upper half-cylinder 82. An internally threaded connecting pipe 811 is fixedly installed at the upper end of the lower half-cylinder 81. The diameter of the internally threaded connecting pipe 811 is smaller than the diameter of the lower half-cylinder 81. An externally threaded connecting pipe 821 is fixedly installed at the lower end of the upper half-cylinder 82. The externally threaded connecting pipe 821 and the internally threaded connecting pipe 811 are threadedly connected. A first limiting ring 812 is fixedly installed in the middle of the inner side of the internally threaded connecting pipe 811. A second limiting ring 822 is fixedly installed at the lower end of the inner side of the externally threaded connecting pipe 821.

[0025] The mounting plate 74 has a mounting hole on the right side. The internal threaded connecting pipe 811 is inserted into the mounting hole. The diameter of the internal threaded connecting pipe 811 is matched with the inner diameter of the mounting hole. The bottom of the lower cylinder 81 abuts against the top of the support base 3.

[0026] A socket 813 is provided in the middle of the right side of the lower half cylinder 81. A deformation monitoring component 83 is installed inside the lower half cylinder 81. The deformation monitoring component 83 is used to provide feedback when deformation occurs during the detection of the spring sheet. The deformation monitoring component 83 includes an L-shaped abutment rod 831 and a spring 832. The L-shaped abutment rod 831 is installed in the socket 813 by a rotating connection, and the top of the L-shaped abutment rod 831 is located on the right side of the lower end of the first limiting ring 812. The spring 832 is installed at the lower end of the L-shaped abutment rod 831 by a fixed connection, and the end of the spring 832 away from the L-shaped abutment rod 831 is fixedly connected to the inner rear wall of the lower half cylinder 81. A support plate 833 is fixedly installed in the middle of the rear end of the lower half cylinder 81, and the top of the support plate 833 abuts against the bottom of the L-shaped abutment rod 831.

[0027] In this embodiment of the utility model, the core electrical structure of the preferred embodiment is a servo motor 73 and a hydraulic cylinder 5. Before the device is started, the upper half-cylinder 82 and the lower half-cylinder 81 are fixed by the threaded engagement of the external threaded connecting pipe 821 and the internal threaded connecting pipe 811, and the spring is limited between the first limiting ring 812 and the second limiting ring 822. During the test, the power supply of the servo motor 73 is first turned on. The output shaft of the servo motor 73 drives the limiting plate 72 to rotate in the bearing 71. The mounting plate 74 on the right side of the limiting plate 72 then drives the clamping mechanism 8 to rotate as a whole, realizing the switching of the spring detection direction. After the direction adjustment is completed, the power supply of the hydraulic cylinder 5 is turned on, and the hydraulic cylinder 5 pushes the detection rod 6 to perform the detection operation. During the detection process, if the spring is deformed, it will squeeze the L-shaped abutment rod 831. The L-shaped abutment rod 831 rotates around the insertion hole 813 and compresses the spring 832. The support plate 833 provides limiting support for the L-shaped abutment rod 831, and the deformation feedback is realized by the displacement change of the L-shaped abutment rod 831. The internal threaded connecting pipe 811 is fitted with the mounting hole of the mounting plate 74, ensuring the stability of the connection between the clamping mechanism 8 and the flipping mechanism 7. The bottom of the lower cylinder 81 abuts against the support base 3, further improving the detection stability.

[0028] In one embodiment of this utility model, the servo motor 73, together with the bearing 71 and the limiting plate 72, forms a flipping mechanism 7, which realizes the automated and precise flipping of the clamping mechanism 8, completely eliminating manual inversion operations, greatly improving detection efficiency. Furthermore, the servo motor 73 has high control precision, ensuring accurate spring flipping angles and improving the reliability of detection data. The threaded connection design of the internal threaded connecting pipe 811 and the external threaded connecting pipe 821 in the clamping mechanism 8 facilitates the assembly and disassembly of the upper half-cylinder 82 and the lower half-cylinder 81. Simultaneously, the first limiting ring 812 and the second limiting ring 822 can securely limit the movement of springs of different specifications, expanding the applicability of the device.

[0029] The deformation monitoring component 83 enables real-time feedback of deformation during the spring sheet detection process. The coordinated action of the L-shaped abutment rod 831, spring 832, and support plate 833 can promptly capture the deformation of the spring sheet, facilitating quick processing by staff, preventing unqualified spring sheets from flowing into subsequent processes, and improving product quality.

[0030] The rounded corner design at the upper end of the support base 3, combined with the buffering effect of the elastic support pad 2, effectively protects the clamping mechanism 8 from damage. It can support the clamping mechanism 8 while also assisting the clamping mechanism 8 in rotating. The L-shaped limit frame 4 ensures the stable installation of each component, and the abutting fit between the lower half-cylinder 81 and the support base 3 further improves the overall stability and service life of the device.

[0031] The working principle of this utility model is as follows: When the device is working, the spring to be tested is first placed on the support seat 3 at the upper end of the elastic support pad 2 in the rectangular groove 11 of the base 1. The spring is limited and fixed by the clamping mechanism 8. Specifically, the internal threaded connecting pipe 811 of the lower half cylinder 81 and the external threaded connecting pipe 821 of the upper half cylinder 82 are threaded together to limit the spring between the first limiting ring 812 and the second limiting ring 822. At the same time, the internal threaded connecting pipe 811 is inserted into the mounting hole of the mounting plate 74 on the right side of the limiting plate 72 in the flipping mechanism 7 to ensure a stable connection between the clamping mechanism 8 and the flipping mechanism 7. When it is necessary to test the spring in different directions, the servo motor 73 is powered on, and its output shaft drives the limiting plate 72 to rotate in the bearing 71 at the lower right end of the L-shaped limiting frame 4, and then through the mounting plate 7 4. The clamping mechanism 8 and the spring are rotated as a whole, eliminating the need for manual inversion. After rotation, the hydraulic cylinder 5 is powered on, and its output pushes the detection rod 6 towards the spring to complete the spring detection operation. During the detection process, if the spring is deformed, it will squeeze the L-shaped abutment rod 831, which is rotatably installed in the lower cylinder 81 through the insertion hole 813. This causes the L-shaped abutment rod 831 to rotate around the insertion hole 813 and compress the spring 832, which is fixed to the rear wall of the lower cylinder 81. The support plate 833 provides a limiting support for the bottom of the L-shaped abutment rod 831. The deformation feedback of the spring is achieved through the displacement change of the L-shaped abutment rod 831. At the same time, the bottom of the lower cylinder 81 abuts against the top of the support seat 3, and the L-shaped limiting frame 4 limits the load of the hydraulic cylinder 5 and the rotation mechanism 7, ensuring the stability and reliability of the entire detection process.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
