The turntable surface is provided with an outer wall clamping assembly and a central positioning assembly. The outer wall clamping assembly includes a positioning block and push-pull quick clamps symmetrically arranged on both sides of the positioning block. The positioning block and the two push-pull quick clamps are arranged in a ring. The central positioning assembly includes a central column, a support plate, a turntable, and multiple inner support blocks. The central column is vertically positioned in the middle of the outer wall clamping assembly and is fixed to the turntable. The support plate is fixed to the central column. Multiple grooves are evenly distributed on the surface of the support plate. The inner support blocks are slidably disposed within the grooves. A connecting rod is vertically fixed to the surface of each inner support block. A screw is fixed to the center of the support plate. The turntable is threadedly connected to the screw at its center. An arc-shaped track is provided on the surface of the turntable corresponding to the position of the connecting rod. When the turntable rotates, the connecting rod can be pushed back and forth via the arc-shaped track.

[0006] The end of the inner support block furthest from the central column has an arc-shaped surface.

[0007] Preferably, in order to facilitate the rotation of the turntable, the turntable has a columnar connecting part in the middle, the columnar connecting part is threadedly connected to the screw, and the top surface of the columnar connecting part is provided with an internal hexagonal hole.

[0008] A limiting block is provided at the top of the slide, and a guide channel is formed between the limiting block and the slide. The inner support block is matched and arranged in the guide channel.

[0009] The sidewall of the positioning block has an arc-shaped positioning part.

[0010] In summary, this application includes at least one of the following beneficial technical effects: the auxiliary fixture for welding the bottom seat of the exhaust pipe drain pan is equipped with an outer wall clamping component and a middle positioning component. The outer wall clamping component first fixes the ring body on the turntable, and the middle positioning component centers and limits the round cover on the ring body, thus performing preliminary pre-fixation, which facilitates subsequent welding and greatly improves welding efficiency. At the same time, the welded bottom seat body is more aesthetically pleasing and has higher welding quality. Attached Figure Description

Detailed Implementation

[0017] The following is in conjunction with the appendix Figure 2-5 This application will be described in further detail.

[0018] This application discloses an auxiliary fixture for welding the bottom seat of an exhaust pipe drain pan, referring to... Figure 2-3The device includes a base 2 and a turntable 3 rotatably mounted on the base 2. The turntable 3 has an outer wall clamping assembly and a central positioning assembly 6 on its surface. The outer wall clamping assembly includes a positioning block 4 and push-pull quick clamps 5 symmetrically arranged on both sides of the positioning block 4. The positioning block 4 and the two push-pull quick clamps 5 are arranged in a ring. The side wall of the positioning block 4 has an arc-shaped positioning part. The central positioning assembly 6 includes a central column 61, a support plate 62, a turntable 63, and multiple inner support blocks 64. The central column 61 is vertically arranged in the middle of the outer wall clamping assembly. The central column 61 is fixed on the turntable 3, and the support plate 62 is fixed on the central column 61. Multiple grooves are evenly opened on the surface of the support plate 62. The inner support block 64 is slidably arranged in the groove. A connecting rod 641 is vertically fixed on the surface of the inner support block 64. A screw 621 is fixed in the middle of the support plate 62. The turntable 63 is threadedly connected to the screw 621 in the middle. An arc-shaped track 631 is opened on the surface of the turntable 63 corresponding to the position of the connecting rod 641. When the turntable 63 rotates, it can push the connecting rod 641 to move back and forth through the arc-shaped track 631.

[0019] Reference Figure 5 In order to fit the through hole in the middle of the round cover, the end of the inner support block 64 away from the central column 61 is an arc-shaped surface.

[0020] Reference Figure 3 The turntable 63 has a columnar connecting part 632 in the middle, which is threaded to the screw 621. The top surface of the columnar connecting part 632 is provided with an internal hexagonal hole 6321.

[0021] Reference Figure 3 A limiting block 7 is provided at the top of the slide, and a guide channel is formed between the limiting block 7 and the slide. The inner support block 64 is matched and set in the guide channel.

[0022] The implementation principle of the auxiliary fixture for welding the bottom seat of the exhaust pipe drain pan according to an embodiment of this application is as follows: Reference Figure 4 and Figure 5 In use, the operator first places the ring on the turntable 3 and makes one side of the ring abut against the positioning block 4. Then, push the push-pull quick clamps 5 on both sides to fix the ring on the turntable 3. After that, put the through hole in the round cover onto the central positioning component 6. The round cover is placed flat on the support plate 62. Insert the wrench into the internal hexagonal socket 6321 and rotate the turntable 63 through the columnar connecting part 632. The turntable 63 pushes the connecting rod 641 through the arc track 631 to drive the inner support block 64 to open outward. Multiple inner support blocks 64 fix the round cover in the center from the middle of the through hole, so that the round cover can be placed coaxially on the ring. When welding, the operator can weld the whole by rotating the turntable 3. The welding is relatively convenient. The welded round cover and the ring have good overall appearance and high quality.

[0023] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
