Description

Equipment for punching central hole in welding fork

Technical Field

The utility model relates to a field of welding fork, concretely relates to center hole equipment is beaten to welding fork.

Background

The center clamp of the existing equipment for welding a fork and punching a center hole adopts a two-way valve, and has the characteristic of pressure maintaining; the descending speed is unchanged without installing a buffer damper. The existing equipment mainly has the following defects: due to the pressure maintaining characteristic of the two-way valve, the phenomenon that the equipment cannot be started normally occurs when the equipment is ventilated; due to centrifugal force, materials can fly out when the gas is insufficient, and potential safety hazards exist; a buffer damper is not adopted, and when the air cylinder is processed, the air cylinder only can be quickly descended without a speed change function.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the not enough of prior art existence, and provide a welding fork centering equipment.

The purpose of the utility model is accomplished through following technical scheme: the welding fork center hole drilling equipment mainly comprises a buffer damper, a center clamp, a bottom plate, a support, a motor, a drill bit, a push rod and a foot support, wherein the foot support is installed at four corners of the bottom plate, the support is installed above the bottom plate, the center clamp is installed at the lower part of the front surface of the support and is driven by the motor installed at the back surface of the support, the drill bit is coaxially arranged above the center clamp and is arranged on the support, the drill bit is pushed by the push rod installed at the top of the support, and the tail end of the motion path of the drill bit is provided with the buffer damper.

The buffer damper is arranged at the position where the drill bit enters the working position, and the speed of the drill bit is reduced.

The central clamp adopts a one-way valve.

The utility model has the advantages that: the utility model adopts the one-way valve, the middle clamp can directly ventilate, the problem of unclamping caused by pressure maintaining is avoided, and one output contact is reduced; the buffering damper is adopted, the air cylinder quickly descends to a position close to the punching position, the working speed can be automatically adjusted, the machining precision is guaranteed, and meanwhile the service life of the cutter is prolonged; the equipment size is 760 x 600 x 1106, the occupied area is small, and the arrangement and the wire grouping are easy; as a special machine for drilling a central hole, the efficiency is greatly improved compared with that of the prior small drilling machine while the safety is ensured, and the production requirement is met.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings:

example (b): as shown in the attached drawings, the welding fork center hole drilling equipment mainly comprises a buffer damper 1, a center clamp 2, a bottom plate 3, a support 4, a motor 5, a drill bit 6, a push rod 7 and a foot support 8, wherein the foot support 8 is installed at four corners of the bottom plate 3, the support 4 is installed above the bottom plate 3, the center clamp 2 is installed on the lower portion of the front face of the support 4, and the center clamp 2 adopts a one-way valve. The central clamp 2 is driven by a motor 5 arranged on the back of the support 4, a drill bit 6 is coaxially arranged above the central clamp 2 and is arranged on the support 4, the drill bit 6 is pushed by a push rod 7 arranged on the top of the support 4, and a buffer damper 1 arranged at the tail end of the motion path of the drill bit 6 is arranged on the front of the support 4. The buffer damper 1 is arranged at the position where the drill bit 6 enters the working position, and starts to reduce the speed of the drill bit 6.

The utility model discloses the working process: the equipment fully considers the safety factor, and the central clamp 2 can be pressed down to start machining after being fully tightened. In the machining process, the drill 6 is quickly fed to a working position, then a central hole is drilled at a slow working speed under the action of the buffer damper 1, the central hole quickly returns to the original position after reaching a final position, and the central clamp 2 automatically loosens after reaching a set time to complete a complete machining process.

It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
