Technical Field

[0001] The present invention relates to a fixture for welding strip-type clamps with clamping blocks, belonging to the technical field of welding fixtures. Background Technique

[0002] The welding of clamp steel strips is a special process, and whether the steel strip welding is qualified is directly related to the quality of the clamp.

[0003] Traditional welding fixtures only have ordinary pressing structures, which only fix the whole part and cannot limit the clamping blocks that can move freely on the hoop belt. Once the clamping blocks move during welding, it will directly affect the welding quality. Summary of the Invention

[0004] To solve the problems in the background technique, the present invention provides a fixture for welding strip-type clamps with clamping blocks.

[0005] To achieve the above object, the present invention adopts the following technical solution: a fixture for welding strip-type clamps with clamping blocks, including an assembly base, a positioning sleeve, and a stop block; a positioning sleeve is fixedly provided at the upper end of the assembly base, and a plurality of stop blocks are provided on the outer wall of the positioning sleeve.

[0006] Compared with the prior art, the beneficial effect of the present invention is:

[0007] By evenly arranging stop blocks on the positioning sleeve, the present invention restricts the position of the clamping blocks of the part, thereby avoiding the random movement of the clamping blocks during welding, enabling the hoop belt to be uniformly stressed during welding, ensuring the welding quality of the clamp, and filling the industry gap of the assembly welding fixture for strip-type clamps with clamping blocks.

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0015] Embodiment 1:

[0016] A fixture for welding a strip-type clamp with a clamping block includes an assembly base 1, a positioning sleeve 2, and a stop block 22; a through hole is provided through the thickness direction of the assembly base 1, and a positioning sleeve 2 is fixedly provided at the upper end of the through hole of the assembly base 1. Specifically: the positioning sleeve locating pin is press-fitted on the assembly base 1, the inner diameter of the assembly base 1 is centered, the positioning sleeve locating pin is angularly positioned, the positioning sleeve 2 is installed, and three screws are used to fasten the assembly base 1 and the positioning sleeve 2 from the opposite direction. A plurality of stop blocks 22 are evenly distributed along the circumferential direction of the outer wall of the positioning sleeve 2.

[0017] The combined part 3 is sleeved on the outside of the positioning sleeve 2, and a plurality of stop blocks 22 are installed in the gaps between the clamping blocks of the part 3, playing a role in limiting and angular positioning.

[0018] A positioning block 12 is further provided at the upper end of the assembly base 1. The positioning block 12 is arranged outside the positioning sleeve 2 and is in contact with the part 3. Specifically: two cylindrical pins are press-fitted and fixed on the assembly base 1, the positioning block 12 is installed, and screws are screwed in to fix the positioning block 12 on the assembly base 1. By providing the positioning block 12, rapid positioning of the welding part of the part 3 can be achieved.

[0019] A plurality of pressing plates 9 are evenly distributed along the circumferential direction at the upper end of the positioning sleeve 2. The pressing plates 9 are used to axially press the part 3.

[0020] A wear-resistant (rubber) layer is provided at the lower end of each pressing plate 9 to avoid damaging the part 3.

[0021] A plurality of pressing plate positioning pins 23 corresponding to the plurality of pressing plates 9 one by one are press-fitted at the upper end of the positioning sleeve 2, and the pressing plates 9 are quickly positioned through the pressing plate positioning pins 23.

[0022] There are also a plurality of pressing mechanisms on the assembly base 1. The plurality of pressing mechanisms are arranged around the positioning sleeve 2, and the pressing mechanisms are used to radially press the part 3, and two of the pressing mechanisms are arranged at the welding part.

[0023] Each pressing mechanism includes a support plate 4, a screw rod 5, a pressing block 8, and a rotating nut 7; the lower end of the support plate 4 is vertically and fixedly connected to the assembly base 1, the upper end of the support plate 4 is threadedly connected to the screw rod 5, the inner end of the screw rod 5 is provided with the pressing block 8, and the outer end of the screw rod 5 is fixed with the rotating nut 7.

[0024] The inner end of the briquetting block 8 is provided with an anti-damage (rubber) layer to avoid damaging the part 3.

[0025] Embodiment 2:

[0026] The difference between this embodiment and Embodiment 1 lies in that:

[0027] Since the hoop is a special stainless steel strip in semi-hard or hard state, it is difficult to master the bending springback degree and elongation coefficient. Through continuous trial bending, the bending and elongation properties of stainless steel are understood, and a special hoop bending mechanism is designed and manufactured. Compared with the traditional bending mechanism, it has a precise positioning device, can accurately position, and has an additional center engraved line, which can ensure the bending accuracy and dimensional requirements of the hoop.

[0028] The fixture further includes a hoop bending mechanism, and the hoop bending mechanism includes a bending mechanism base 15, a mounting seat 17, and an insertion rod 21; four mounting seats 17 are arranged in an array at the upper end of the bending mechanism base 15 through cylindrical pins and screws, and an insertion rod 21 is inserted on each two corresponding mounting seats 17. A production standard engraved line 18 is provided on the upper surface of the bending mechanism base 15 to bend the hoop according to the requirements of the design drawing to ensure the dimensional requirements.

[0029] Before assembly, place the straight hoop on the bending mechanism base 15, manually bend both ends around the insertion rod 21, and bend both ends of the hoop again according to the position of the production standard engraved line 18 on the bending mechanism base 15 to form a specified shape and meet the dimensional requirements.

[0030] A hoop positioning pin 16 is provided at the upper end of the bending mechanism base 15 to fix the position of the hoop by using the hoop positioning pin 16.

[0031] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent conditions of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.

[0032] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
