Abstract
The utility model relates to the technical field of tool fixtures, and discloses a self-loosening tool fixture, which comprises a bottom plate and a clamping block; a positioning block is arranged at the central position of the bottom plate; the number of the clamping blocks is two; the two clamping blocks are symmetrically distributed on two sides of the positioning block; two parallel elastic slide rails are arranged on the bottom plate along the width direction of the bottom plate; the clamping block is arranged on the elastic slide rail through a slide block; a return spring is arranged on one side of the clamping block, which is far away from the positioning block; the other end of the return spring is arranged on the bottom plate; the clamping block is clamped by a cylinder on the lathe. The automatic clamping and releasing actions of the clamping blocks can be realized through the matching of the air cylinder on the lathe and the reset spring, manual operation is replaced, and the working efficiency is improved. The mounting plate is provided with a plurality of mounting holes for mounting the bottom plate on the lathe. The mounting plates with two upward bent sides can collect part of scraps generated by machining, so that the lathe is convenient to clean; meanwhile, the two sides of the bending design are convenient for operators to take, and the tool clamp is convenient to replace.
Description
Technical Field
The utility model relates to a frock clamp of machining equipment, in particular to from elasticity frock clamp.
Background
Most of existing tool fixtures fix products to be machined through limiting or positioning pins, and operators are generally required to manually adjust the positions of the limiting blocks or the positioning pins to clamp the ears of the products.
SUMMERY OF THE UTILITY MODEL
The utility model provides a technical problem provide a from elasticity frock clamp, can be automatic will wait to process the work piece and press from both sides tightly and relax, improve lathe production efficiency.
The utility model provides a technical scheme that its technical problem adopted is: a self-tightening tool clamp comprises a bottom plate and a clamping block; a positioning block is arranged at the central position of the bottom plate; the number of the clamping blocks is two; the two clamping blocks are symmetrically distributed on two sides of the positioning block; two parallel elastic slide rails are arranged on the bottom plate along the width direction of the bottom plate; the clamping block is arranged on the elastic slide rail through a slide block; a return spring is arranged on one side of the clamping block, which is far away from the positioning block; the other end of the return spring is arranged on the bottom plate; the clamping block is clamped through a cylinder on the lathe. The automatic clamping and releasing actions of the clamping blocks can be realized through the matching of the air cylinder on the lathe and the reset spring, manual operation is replaced, and the working efficiency is improved.
Further, the method comprises the following steps: two ends of the bottom plate in the length direction are provided with mounting plates bent upwards; the mounting plate is provided with a plurality of mounting holes for mounting the bottom plate on the lathe. The mounting plates with two upward bent sides can collect part of scraps generated by machining, so that the lathe is convenient to clean; meanwhile, the two sides of the bending design are convenient for operators to take, and the tool clamp is convenient to replace.
Further, the method comprises the following steps: and the bottom plate is also provided with a limiting block for preventing the clamping block from separating from the elastic slide rail. The limiting block can prevent the clamping block and the sliding block from being separated from the sliding rail.
Drawings
Fig. 1 is a self-tightening tool clamp.
Labeled as: 100. a base plate; 101. positioning blocks; 102. the slide rail is loosened and tightened; 103. a return spring; 104. a limiting block; 110. mounting a plate; 111. mounting holes; 120. and (5) clamping blocks.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in fig. 1, a self-tightening tool clamp includes a base plate 100 and a clamping block 120; a positioning block 101 is arranged at the center of the bottom plate 100; the number of the clamping blocks 120 is two; the two clamping blocks 120 are symmetrically distributed on two sides of the positioning block 101; two parallel elastic slide rails 102 are arranged on the bottom plate 100 along the width direction of the bottom plate 100; the clamping block 120 is mounted on the elastic slide rail 102 through a slide block; a return spring 103 is arranged on one side of the clamping block 120 away from the positioning block 101; the other end of the return spring 103 is arranged on the bottom plate 100; the clamping block 120 is clamped by a cylinder on a lathe.
On the basis, as shown in fig. 1, the two ends of the bottom plate 100 in the length direction are provided with mounting plates 110 bent upwards; the mounting plate 110 is provided with a plurality of mounting holes 111 for mounting the base plate 100 to a lathe.
On the basis, as shown in fig. 1, the bottom plate 100 is further provided with a stopper 104 for preventing the clamping block 120 from separating from the flexible slide rail 102.
In actual production, the work fixture is installed on a lathe, an operator places a workpiece to be machined on a bottom plate 100, positions the workpiece through a positioning block 101, and pushes two clamping blocks 120 to approach through a cylinder on the lathe before the lathe starts to work so as to clamp the workpiece, so that the workpiece is automatically clamped; after the machining is finished, the air cylinder on the lathe resets, the clamping block 120 is attached to the limiting block 104 again under the pulling of the reset spring 103, and the action of automatically releasing the workpiece is realized.
The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
