Abstract

The utility model relates to a spring assembly frock, including base and support, fixed mounting directly moves double-pole cylinder and presss from both sides and indicates the cylinder on the support, but presss from both sides the pneumatic clamp that indicates the cylinder and indicates clamping spring, directly moves and is equipped with positioning die on the double-pole cylinder, and positioning die fixes the work piece, directly moves the motion of double-pole cylinder in vertical side, can drive the work piece on the positioning die and impress in the spring. The workpiece is fixed on the positioning die, the spring is clamped by the clamping finger cylinder, and when the positioning die is driven to press downwards by the direct-acting double-rod cylinder, the workpiece on the positioning die, such as a threaded pin, can be pressed towards the spring by pneumatic impact. The pneumatic impact force direction of the direct-acting double-rod always faces to the middle shaft of the spring, the force is concentrated, and the mounting effect is good.

Description

Spring assembly fixture

Technical Field

The utility model relates to a spring assembly frock.

Background

During the assembly production process, a workpiece, such as a threaded pin, needs to be pressed into the spring, and the threaded pin and the spring are connected in an interference fit mode. The traditional method adopts manual press fitting, has low assembly efficiency, and is easy to damage workpieces if the control is not good for press fitting of moment or the force is incorrect.

Disclosure of Invention

In view of this, the utility model aims at providing an adopt direct acting cylinder pressure equipment spring, operating efficiency is high, do not receive the artifical nondeterminacy influence of exerting oneself and assemble frock.

In order to realize above mesh, the utility model discloses a such spring assembly frock, including base and support, the support on fixed mounting directly move the double-pole cylinder and press from both sides and indicate the cylinder, the pneumatic clamp that presss from both sides and indicate the cylinder indicate that can press from both sides tight spring, directly move and be equipped with positioning die on the double-pole cylinder, positioning die fixed work piece, the motion of directly moving the double-pole cylinder in vertical side, can drive the work piece on the positioning die among the spring of impressing. Compared with the prior art, the invention has the beneficial technical effects that: through the arrangement of the structure, the workpiece is fixed on the positioning die, the spring is clamped by the clamping finger cylinder, and when the positioning die is driven to press down by the direct-acting double-rod cylinder, the workpiece on the positioning die, such as the threaded pin, can be pressed to the spring by pneumatic impact. The pneumatic impact force direction of the direct-acting double-rod always faces to the middle shaft of the spring, the force is concentrated, and the mounting effect is good.

In particular, symmetrical jigs are arranged in the middle of the pneumatic clamping fingers, and a square space for accommodating the spring is formed in the center of each jig. The jig moves along with the action of the pneumatic clamping fingers, and the included angle of the square space is more suitable for being tangent to the circular periphery of the spring and stabilizing the spring and not moving in the assembling process.

Particularly, an air cylinder mounting seat is fixed on the support, and the clamping finger air cylinder can be fixed on the air cylinder mounting seat. Through the arrangement of the structure, the action direction of the clamping fingers of the clamping finger cylinder can accord with the vertical arrangement of the spring.

Particularly, a microswitch is fixed on the support, an ejector rod is arranged above a pressure head of the microswitch, the ejector rod can penetrate through a through hole in the air cylinder mounting seat and extend into a through hole of the spring, a stroke adjusting plate is further arranged on the support, and the microswitch is fixed on the stroke adjusting plate. Firstly, a stroke adjusting plate is adjusted to control the depth of pressing a workpiece into a spring, and when the downward pressure applied by a positioning die is transmitted to a pressure head of a microswitch through the workpiece and an ejector rod in sequence, the microswitch sends a signal for finishing assembly to a control center.

Particularly, the support is fixedly provided with an insert, and the ejector rod penetrates through a through hole of the insert. Because the length of ejector pin is longer, through wearing the ejector pin in the through-hole of inserting, can protect the ejector pin to transmit evenly at epaxial pressure.

Detailed Description

As shown in fig. 1-4, a spring assembly fixture includes a base 1 and a support 2, a linear-motion double-rod cylinder 3 and a clamping finger cylinder 5 are fixedly installed on the support 2, a pneumatic clamping finger 52 of the clamping finger cylinder 5 can clamp a spring a2, a positioning mold 4 is arranged on the linear-motion double-rod cylinder 3, the positioning mold 4 fixes a workpiece, the workpiece is specifically a threaded pin a1, and the linear-motion double-rod cylinder 3 moves in the vertical direction to drive a workpiece a1 on the positioning mold 4 to be pressed into a spring a 2.

The middle of the pneumatic clamping finger 52 is provided with a symmetrical jig 10, and the center of the jig 10 forms a square space for accommodating the spring A2.

An air cylinder mounting seat 51 is fixed on the support 2, and the clamping finger air cylinder 5 can be fixed on the air cylinder mounting seat 51.

A microswitch 8 is fixed on the support 2, an ejector rod 6 is arranged above a pressure head of the microswitch 8, the ejector rod 6 can pass through a through hole in the air cylinder mounting seat 51 and extend into a through hole of a spring A2, a stroke adjusting plate 9 is further arranged on the support 2, and the microswitch 8 is fixed on the stroke adjusting plate 9.

The stroke adjusting plate 9 has a vertical strip-shaped hole 92, and the diameter of the end face of the fixing screw 91 is larger than the width of the strip-shaped hole 92. By moving the stroke adjusting plate 9 and tightening the fixing screw 91, the position of the ejector rod 6 on the Y axis can be adjusted, and the purpose of controlling the pressing depth of the workpiece is achieved.
