Description
Technical Field
The utility model relates to a welding jig's structure, especially an anchor clamps limit structure.
Background
The existing clamp limiting mechanism fixes a cylinder on a positioning seat, four connecting bolts are used for connection, a cylinder push rod and a pushing block are connected through a connector, the pushing block is clamped in the positioning seat, a positioning seat cover plate is tightly covered by the four bolts, the pushing block is prevented from deviating from the positioning seat in the use process, safety problems are caused, in the use process, limiting stress is mainly concentrated on the head of the pushing block, and therefore a limiting block is a vulnerable part, but the manufacturing period of the limiting block is longer, the number of machining processes is large, linear cutting equipment needs to be used, subsequent gap grinding is troublesome, and the manufacturing cost is high. The position of the limiting block is weak, and the limiting block is easy to deform or break under the impact force of the cylinder, so that the positioning precision of the product is influenced. Due to long-term deformation and fracture, the subsequent maintenance cost is higher, and the production efficiency is influenced.

The utility model discloses solve above-mentioned prior art's shortcoming, provide a processing is simple, low in cost's anchor clamps limit structure.
The utility model provides a technical scheme that its technical problem adopted: the clamp limiting structure mainly comprises an air cylinder, a positioning seat and a pushing rod, wherein the air cylinder is fixed on one side of the positioning seat, the pushing rod is located in the positioning seat and connected with an air cylinder push rod of the air cylinder, a limiting groove is formed in the positioning seat, and a limiting pin is arranged in the limiting groove.
The push rod is provided with a limiting pin mounting hole, the limiting pin mounting hole is matched with the limiting pin, and the limiting pin is inserted into the limiting pin mounting hole.
The push rod is directly connected with the push rod of the air cylinder through threads.
And a positioning seat cover plate is fixed on the positioning seat.
The utility model discloses profitable effect is: the structure of the utility model effectively reduces the product quality defect caused by the limit deformation fracture, and reduces the product reject ratio; the limiting pin has the advantages of simple processing technology, standardization, reduction of the manufacturing cost of the clamp, prolongation of the service life of the clamp and shortening of the maintenance time.

Description of reference numerals: the device comprises a cylinder 1, a positioning seat 2, a cylinder push rod 3, a push rod 4, a positioning seat cover plate 5, a limiting pin 6, a limiting groove 7 and a limiting pin mounting hole 8.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in the figure, the clamp limiting structure mainly comprises a cylinder 1, a positioning seat 2 and a pushing rod 4, wherein the cylinder 1 is fixedly connected to one side of the positioning seat 2 through four connecting bolts, the pushing rod 4 is located in the positioning seat 2 and is connected with a cylinder push rod 3 of the cylinder 1, and the pushing rod 4 is in direct threaded connection with the cylinder push rod 3. The positioning seat 2 is provided with a limiting groove 7, a limiting pin 6 is arranged in the limiting groove 7, the pushing rod 4 is provided with a limiting pin mounting hole 8, the limiting pin mounting hole 8 is matched with the limiting pin 6, and the limiting pin 6 is inserted into the limiting pin mounting hole 8. The positioning seat cover plate 5 is fixed on the positioning seat 2 through four bolts, so that the positioning seat 2 is prevented from being deviated in the use process of the pushing rod 4, the pushing rod 4 is directly processed into a straight rod, the structure is free from abnormal structures, linear cutting processing is not needed, and the processing technology is simplified. The strength of the limiting pin 6 and the limiting groove 7 of the limiting mechanism is high, and the problems of deformation and fracture caused by weak limiting strength are effectively reduced. Although the limiting pin 6 is a vulnerable part, the processing is simple, the manufacturing cost is low, and the maintenance cost and the maintenance time are effectively reduced.
In the use process, the pushing action of the cylinder push rod 3 drives the pushing rod 4 to generate displacement, so that the limiting pin 6 moves in the limiting groove 7.
The utility model discloses an adopt 6 and spacing groove 7's matching of spacer pin to carry on spacingly, with the higher spacing groove 7 of spacing stress point transfer strength and 6 positions of spacer pin, avoid answering the weak deformation and the fracture problem that causes of spacing intensity.
In addition to the above embodiments, the present invention may have other embodiments. All the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
