Description

Technical Field

[0001] This utility model belongs to the field of fixture technology, and in particular relates to a welding and fixing fixture for automotive parts. Background Technology

[0002] Chinese Patent ZL202420933992.2 relates to an automotive welding fixture, including an operating table, a fixed plate and a clamping plate on the operating table, a telescopic mechanism between the fixed plate and the operating table, a fixing mechanism on the fixed plate, an adjustment box on the operating table, an opening at one end of the adjustment box with an adjustment post on the opening, a bearing seat at the other end of the adjustment box, an adjustment shaft between the bearing seat and the clamping plate, a rectangular groove at one end of the adjustment shaft, a rectangular post between the adjustment post and the rectangular groove, an adjustment groove on the opening with an internal toothed ring, a beveled toothed ring on the adjustment post, and a sliding groove on the clamping plate with a clamping block. This welding fixture can flexibly adjust the angle of the clamping plate through the adjustment post to meet the needs of different welding angles.

[0003] The aforementioned welding fixture uses two clamping blocks and an electromagnetic lock to hold the iron plate in place. While this allows for quick workpiece fixation, the magnetic field generated by the electromagnetic lock may cause magnetic blow of the welding arc, affecting welding quality. Furthermore, the electromagnetic lock carries the risk of malfunction; if it fails during welding, the workpiece may fall, posing a safety hazard. Utility Model Content

The front part of the drive rod is a wedge structure that mates with the wedge surface of the wedge block of the two clamping arms. The base is provided with a drive rod slide that supports the drive rod and allows the drive rod to move in the forward and backward direction.

[0006] Furthermore, a return spring is fitted on the clamping arm guide rail, and the return spring is located between the two clamping arms.

[0007] Furthermore, a throttle is provided at the rear end of the drive rod.

[0008] Furthermore, the wedge structure at the front of the drive rod is provided with an elongated groove; the base is provided with a drive rod lock seat, and the drive rod is locked to the drive rod lock seat by a locking bolt.

[0009] Furthermore, a base is also provided; the base and the lower part of the pedestal are hinged together, and the pedestal is provided with a locking structure for locking the hinged part.

Detailed Implementation

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model. Example

[0016] A welding and fixing fixture for automotive parts includes two clamping mechanisms 1 and a forward and reverse lead screw slide 2; the two clamping mechanisms 1 are respectively mounted on two sliders of the forward and reverse lead screw slide 2; the clamping mechanism 1 includes a base 1-1, a base 1-2, a first locking bolt 1-3, a drive rod 1-4, a clamping arm 1-5, a clamping plate 1-6, a return spring 1-7, and a second locking bolt 1-8;

[0017] The base 1-1 has a clamping arm guide rail 1-1-2 at the front, and two clamping arms 1-5 are respectively installed at both ends of the clamping arm guide rail 1-1-2 and slide towards each other along the clamping arm guide rail 1-1-2; a return spring 1-7 is sleeved on the clamping arm guide rail 1-1-2, and the return spring 1-7 is located between the two clamping arms 1-5; a detachable clamping plate 1-6 is installed at the front end of the clamping arm 1-5;
