Description

Technical Field

[0001] The utility model relates to the technical field of tail pipe processing, in particular to a tail pipe welding fixture with good fixability. Background Art

[0002] In order to ensure the accuracy of the muffler tail pipe welding, workers usually place the muffler tail pipe on a fixture for welding. This fixture generally includes a bottom plate, a positioning seat, a base, and a gland and a slide rod located above the positioning seat. When welding the muffler tail pipe, the worker first places the bottom of the muffler tail pipe on the positioning seat, and then moves the slide rod downward to press the gland connected to the bottom of the slide rod toward the muffler tail pipe. Finally, the muffler tail pipe will be pressed between the gland and the positioning seat. In order to prevent the gland from falling under the action of its own gravity after moving up, a stop pin is usually connected between the slide rod and the base. That is, when the slide rod moves up a certain distance, the worker can insert the stop pin into the pin hole provided on the slide rod and the base, thereby achieving the purpose of preventing the gland from falling under the action of its own gravity.

[0003] However, when the stop pin is inserted into the pin hole provided on the slide bar and the base, since the stop pin is provided separately, when the slide bar drives the gland to move upward, the worker has to use two hands to operate at the same time, that is, one hand moves the slide bar upward, and the other hand picks up the stop pin and inserts it into the pin hole provided on the slide bar and the base when the slide bar moves to a certain height. The worker can operate the welded tail pipe only after fixing the slide bar. This operation method not only brings certain troubles to the worker's operation in the actual production process, but also affects the production efficiency.

[0004] Therefore, the utility model provides a tail pipe welding fixture with good fixation to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a tail pipe welding clamp with good fixation. After use, the cover block and the sleeve block can be connected and fixed, which effectively solves the cumbersome process of using the traditional clamp to move the slide rod with one hand to drive the cover block while using the other hand to operate the stop pin. It not only facilitates the operation of the workers, but also greatly improves the production efficiency.

[0033] Reference Figure 1-4 The utility model provides an embodiment: a tail pipe welding fixture with good fixation, including a base 1, a mounting seat 2 is fixedly arranged at the midpoint of the rear end of the base 1, a screw rod 4 is threadedly sleeved on the upper end surface of the mounting seat 2, a sleeve seat 3 is rotatably sleeved on the outer side of the screw rod 4, a connecting rod 6 is fixedly connected to the front end surface of the sleeve seat 3 through a connecting block 5, a sleeve block 8 is fixedly arranged on the front end surface of the connecting rod 6, a threaded rod 7 is threadedly penetrated on the upper end surface of the sleeve block 8, and a cover block 10 is fixedly arranged on the lower end surface of the threaded rod 7, that is, when the height of the cover block 10 needs to be adjusted, the threaded rod 7 can be used to adjust the distance from the sleeve block 8 and the screw rod 4 can be used to change the vertical height on the mounting seat 2 to complete the required height adjustment, and a connecting hole 9 is opened at the midpoint of the upper end surface of the cover block 10;

[0034] A movable groove 11 is provided at the midpoint of the upper end surface of the base 1, and an adjustment mechanism 13 is rotatably arranged in the movable groove 11. The adjustment mechanism 13 includes an adjustment rod 1302, and sliders 15 are threadedly sleeved on both ends of the adjustment rod 1302. Positioning seats 12 are fixedly provided on the upper end surfaces of the two sliders 15. The adjustment mechanism 13 can be used to complete the adjustment of the positions of the two positioning seats 12. A guide groove 14 is provided at the midpoint of the front end surface of the mounting seat 2, and a guide rod 16 is slidably and clamped in the guide groove 14.

[0035] Specifically, according to the above-mentioned embodiment, when using the clamp, the tail pipe of the muffler to be welded is placed at the midpoint of the upper end of the base 1. Since a knob block 1301 is fixedly provided at one end of the adjusting rod 1302, and the knob block 1301 is rotatably provided on one side of the outer wall of the base 1, the adjusting rod 1302 is an adjusting rod 1302 with threads at both ends. At this time, the knob block 1301 is used to drive the adjusting rod 1302 to rotate, and the two sliders 15 located at both ends of the adjusting rod 1302 are relatively displaced, and the two sliders 15 are slidably embedded in the movable groove 11, and the two sliders 15 are respectively located at both sides of the inside of the movable groove 11, that is, at this time, the two sliders 15 slide in the movable groove 11 and drive the upper end positioning seat 12 to move synchronously relative to each other, so that the two positioning seats 12 clamp the two sides of the outer wall of the muffler tail pipe to be welded;

[0036] After completing the clamping on both sides, according to the required height of the cover block 10, first use the rotation of the screw 4 to shrink it into the inner mounting seat 2.
