Description

Technical Field

[0001] This utility model relates to welding support devices, and more particularly to an adjustable stroke type battery box welding support device. Background Technology

[0002] The existing battery box welding support device has no adjustable stroke and the distance between support points is fixed. When placing the support device, it is necessary to ensure that the spacing dimension meets the placement conditions; if the spacing is too long, the support device will not be able to provide support, and if the spacing is too short, the support device will not be able to be placed.

[0003] Furthermore, when traditional battery box welding support devices are placed inside the battery box, a wooden mallet is needed to strike the support device to make it snap into place. Due to the resistance, it is difficult to ensure the perpendicularity of the support device to the support surface, thus making it difficult to control the shrinkage caused by welding deformation. Utility Model Content

[0004] To address the shortcomings of the aforementioned technologies, this utility model provides an adjustable stroke battery box welding support device.

[0005] To solve the above technical problems, the technical solution adopted by this utility model is: an adjustable stroke type battery box welding support device, which includes a support rod, a support head, an internal hexagon bolt, and a pad;

[0006] The support rod has threaded holes at both ends, and there are two sets of support heads. The two sets of support heads are connected to the threaded holes of the support rod through thread matching of their screw sections.

[0007] The support rod has a through-hole threaded countersunk hole. The socket head cap screw is screwed into the countersunk hole of the support rod and then passes downward to connect the pad.

[0008] Preferably, the support head has a columnar screw head, and the screw section of the support head is vertically fixed to one side of the screw head.

[0009] Preferably, the screw head has a circumferential hole.

[0010] Preferably, the support rod is provided with two sets of socket head cap screws, which are symmetrically distributed.

[0011] Preferably, the pad has a threaded hole at the center for matching hexagon socket bolts.

[0012] Preferably, the bottom end of the support rod is horizontal.

[0013] This utility model discloses an adjustable stroke battery box welding support device, which uses a threaded structure to achieve stroke adjustment in both height and length directions. The first and last support heads are both threaded. When the two end support heads are screwed out and pressed against the support surface of the battery box, the support stroke can be adjusted and fixed, and there will be no problem of insufficient support or inability to place the battery box due to excessively long or short distances.

[0014] Meanwhile, since the travel in both the height and length directions of this support device is adjustable and it can be flexibly disassembled, there is no need to use a wooden mallet to strike it, ensuring the placement accuracy of the support device and thus making the two ends of the device evenly stressed.

[0016] Figure 2 This is a schematic diagram showing the state of the present invention when it is used with a battery box.

[0017] In the diagram: 1. Support rod; 2. Support head; 3. Socket bolt; 4. Spacer block; 5. Insertion hole. Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] This utility model discloses an adjustable stroke type battery box welding support device, the structure of which is as follows: Figure 1 As shown, the main structural components include a support rod 1, a support head 2, an internal hex bolt 3, and a pad 4;

[0020] The support rod 1 is detachably assembled with support heads 2 at both ends via threads. Specifically, firstly, threaded holes are provided at both ends of the support rod 1; secondly, there are two sets of support heads 2, each of which is equipped with a screw section. Thus, the support head is connected to the threaded hole of the support rod 1 through the threaded matching of its screw section, so as to realize the spiral detachable installation of the support head 2 and the support rod 1.

[0021] For example Figure 1 As shown, a through-hole threaded countersunk hole is provided on the support rod 1. The countersunk hole is used for screwing in the hexagon socket head cap screw 3. The hexagon socket head cap screw 3 is screwed into the countersunk hole from the upper end of the support rod 1, and then passes down through the countersunk hole to connect to the pad 4 at the bottom of the support rod 1. The pad 4 has a threaded hole in the center to match the hexagon socket head cap screw 3. The height of this support device is adjusted by the threaded connection.

[0022] Preferably, the hexagon socket bolts 3 connected to the support rod 1 are provided in two sets, and the two sets of hexagon socket bolts 3 are symmetrically distributed to achieve balanced support in the height direction.

[0023] Furthermore, preferably, the support head 2 has a columnar screw head to facilitate the rotation operation of the support head 2; structurally, the screw section of the support head 2 is vertically fixed to one side of the screw head of the support head 2.

[0024] Preferably, a circumferential hole 5 can be made on the screw head, and the through hole can be used for the insertion of the force rod, with both ends of the force rod exposed to facilitate the rotation operation of the support head 2 inside the battery box.

[0025] Preferably, the bottom end of the support rod 1 is horizontal, so as to better identify whether the support rod 1 is in a horizontal state.

[0026] Therefore, it can be seen that the adjustable stroke type battery box welding support device disclosed in this utility model, such as Figure 2 As shown, during use, first connect the support head and support rod and rotate to adjust to the shortest stroke. Connect the support rod and pad with hex bolts. Rotate the two hex bolts to adjust to a suitable height so that the support device is parallel to the placement plane. When placing the support device, keep the top of the support head perpendicular to the support surface. Rotate the tail support head to tighten against the support surfaces on both sides. After the support device is adjusted, the force of welding shrinkage will act on the support device through the support head.

[0027] Compared with existing technologies, this invention has the following technical advantages:

[0028] 1) Quick installation: This welding support device adopts a quick disassembly and installation method. During installation, simply connect the various parts with threads and bolts. Disassembly is convenient and quick. In addition, different parts other than the support rod can be mechanically disassembled and replaced according to actual needs.

[0029] 2) Flexible connection: Since this welding support device will generate support force within a certain stroke range, and when adjusting the stroke, you only need to rotate the support heads at both ends to tighten the support surface, there will be no situation where the welding support device is not in place due to adjustment error.

[0030] 3) Easy disassembly: Due to welding deformation, the span size shrinks. Traditional support devices cannot be easily removed at this time. However, this welded support device can be easily removed by simply inserting a force rod into the reserved hole on the support head and rotating the support head.

[0031] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
