Description

Technical Field

[0001] This utility model belongs to the field of riveting equipment, and in particular relates to a riveting mechanism for a compensation plate for a German-made clamp. Background Technology

[0002] In the application of pipelines, clamps can not only connect pipelines to each other, but also fix pipelines and limit pipeline displacement. Expansion plates can be clamped onto the pipeline to further strengthen the connection with the pipeline. In order to ensure that the force is evenly distributed, the expansion plates need to be set opposite to the clamp connection head.

[0003] In the existing processing technology, the claws of the compensation piece are fastened to the edge of the clamp, and then the clamp and the compensation piece are riveted together. However, the existing technology does not have a special tooling, and the riveting position is inside the clamp, which is not easy to operate. Moreover, it is easy to cause displacement during the riveting process, which reduces the riveting quality and causes the compensation piece to fall off. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a riveting mechanism for compensating plates for German-made eccentric clamps, which can systematize the riveting process of compensating plates, ensure riveting quality, and greatly improve the product quality and production efficiency of German-made eccentric clamps.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a riveting mechanism for compensating plates for German-style clamps, including a positioning clamp, a placement platform and a pressure head;

[0006] The positioning fixture is used to limit the placement position of the clamp, including a support platform that provides support for the compensation part of the clamp;

[0007] The placement platform provides support for the riveting of the clamp and the compensation piece. The placement platform is provided with two intersecting placement channels for placing the clamp and the compensation piece, respectively.

[0008] A pressure hole is provided in the longitudinal placement channel, and the pressure head is used to apply downward pressure to the pressure hole so that the clamp is riveted to the compensation piece.

[0009] Furthermore, the positioning clamp includes a fixing part, on which a groove is provided that matches the outer contour of the connector of the clamp, for preventing the clamp from sliding along the outer surface of the support platform.

[0010] Furthermore, it includes a bracket, which comprises an upper mounting plate and a lower mounting plate.

[0011] Furthermore, an outwardly protruding positioning block is provided on the upper mounting plate, and a through groove matching the positioning block is provided on the fixing part to limit the tilt angle of the groove.

[0012] Furthermore, a protective plate is provided at the front end of the support platform to prevent the compensation part from falling out.

[0013] Furthermore, the pressure head is extendable and retractable at the lower end of the support platform via a drive mechanism.

[0014] Furthermore, the positioning clamp is detachably connected to the upper mounting plate, and the placement platform is detachably connected to the lower mounting plate.

[0015] Furthermore, the connecting part on one side of the fixing part is connected to the upper mounting plate by bolts.

[0016] The advantages and positive effects of this utility model are:

[0017] 1. Due to the adoption of the above technical solution, the setting of positioning fixtures and placement platform provides riveting fixtures for clamps and compensation plates;

[0018] The positioning fixture can quickly position the clamp. The setting of the fixing part ensures the riveting position of the compensation piece on the clamp, that is, the compensation piece and the connector are set opposite each other. On the other hand, it can prevent the clamp from running on the support platform during the riveting process.

[0019] The crisscrossing placement channels on the placement platform can position the riveting points. Specifically, the horizontal placement channels can limit the placement position of the clamps, and the vertical placement channels can limit the placement position of the compensating pieces. The setting of the pressure holes can ensure that the riveting position is always consistent, prevent the riveting position from shifting, fix the riveting position of the clamps and compensating pieces, and improve the efficiency and quality of the riveting work.

[0020] 2. The positioning block can limit the tilt angle of the slot, so that it matches the position of the clamp connector and prevents the clamp from moving during riveting.

[0021] 3. The positioning clamps and placement platform are detachable, allowing for tooling replacement according to different usage conditions. They are also compatible with different models of clamps and compensation plates. Attached Figure Description

[0032] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0033] like Figures 1 to 3 As shown, this embodiment provides a riveting mechanism for a compensation plate for a German-made clamp, including a positioning clamp, a placement platform 6, and a pressure head 5.

[0034] The positioning fixture is used to restrict the placement of the clamp 7. It includes a fixing part 3 and a support platform 4. The support platform 4 supports the compensation part 73 on the inner wall of the clamp 7. A protective plate 41 is provided at the front end of the support platform 4. The outer wall of the protective plate 41 is higher than the outer wall of the support platform 4 to prevent the compensation part 73 from falling off the support platform 4. The pressure head 5 can extend and retract at the lower end of the support platform 4 by means of an external driving mechanism. The lower end of the pressure head 5 is an arc-shaped protrusion.

[0035] The external drive device is not limited to pneumatic drive, hydraulic drive or other drive methods. In this embodiment, the external drive device can be a cylinder drive, and the pressure head 5 is set on the push rod of the cylinder. In another embodiment, the external drive device can be a hydraulic cylinder drive, and the pressure head 5 is set on the piston rod of the hydraulic cylinder.

[0036] The fixing part 3 is located above the support platform 4. The fixing part 3 is provided with a groove 31 that matches the outer contour of the connector 71 of the clamp 7. By placing the connector 71 into the groove 31, the clamp 7 is prevented from sliding on the outer surface of the support platform 4, and the clamp 7 is quickly positioned.

[0037] The placement platform 6 provides support for the riveting of the compensation piece 72 and the clamp 7. The placement platform 6 has two intersecting placement channels in a "+" shape. The horizontal placement channel 61 is used for placing the clamp 7, and the width of the groove of the horizontal placement channel 61 matches the width of the clamp 7. The vertical placement channel 62 is used for placing the compensation piece 72, and the width of the groove of the vertical placement channel 62 matches the width of the compensation piece 72. A pressing hole 621 is provided in the vertical placement channel 62. The pressing hole 621 is a deep square hole. The center line of the pressing hole 621 is collinear with the center line of the vertical placement channel 62, so that the riveting point is located at the center of the compensation piece 72. The pressing head 5 applies downward pressure to the pressing hole 621, so that the clamp 7 is pressed against the compensation piece 72, and the riveting is completed.

[0038] It includes a bracket 1 and an upper mounting plate 2 and a lower mounting plate 22 disposed on the bracket 1. The positioning clamp is detachably connected to the upper mounting plate 2, and the placement platform 6 is detachably connected to the lower mounting plate 22.

[0039] The upper mounting plate 2 is provided with an outwardly protruding positioning block 21, and the fixing part 3 is provided with a through groove that matches the positioning block 21. The fixing part 3 is fitted into the positioning block 21 through the through groove, thereby limiting the tilt angle of the groove 31.

[0040] A connecting part 32 is provided at the end of the fixing part 3. Both the connecting part 32 and the support platform 4 can be threadedly connected to the upper mounting plate 2 by bolts. The placement platform 6 can be threadedly connected to the lower mounting plate 22 by bolts.

[0041] The working process of this example:

[0042] The cylinder is located at the upper end of the bracket 1, and its push rod drives the extension and retraction of the pressure head 5, so that the claw of the compensation plate 72 is sleeved on the end of the clamp 7 opposite to the connector 71.

[0043] With the connector 71 facing upwards, place the compensation part 73 of the clamp 7 onto the support platform 4. The support platform 4 supports the compensation part 73. The connector 71 is located in the slot 31, the lower end of the clamp 7 is located in the transverse placement channel 61, and the compensation piece 72 is located in the longitudinal placement channel 62.

[0044] The pressure head 5 applies downward pressure to the pressure hole 621, which has riveted the clamp 7 and the compensation piece 72 together.

[0045] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
