Description

Technical Field

[0001] The utility model belongs to the technical field of chain saw guide plate assembly, and relates to a guide plate reciprocating conveyor of a chain saw guide plate welding device. Background Art

[0002] An electric chain saw is a woodworking power tool that uses a rotating chain saw blade for sawing. A chain saw guide is a guide plate used to position and install a saw chain. The chain saw guide is assembled from two outer plates and a middle plate. The middle plate has a thickness and is smaller in volume than the outer plates. Therefore, a guide groove for installing a saw chain is formed between the two outer plates and the middle plate. The guide teeth of the saw chain can reciprocate along the guide groove to cut the object. In the prior art, the production of a chain saw guide requires the two outer plates to be combined, which involves multiple processes such as loading, welding, flipping, and back and forth transportation. Not only are the processes complicated and the synthesis efficiency is low, but it also often requires multiple mechanisms to cooperate in transportation. To this end, people have conducted long-term explorations and proposed various solutions.

[0003] For example, a Chinese patent document discloses a synthesis device for a chainsaw guide plate [application number: 201922178322.6], which places the synthesized chainsaw guide plate on a limit column, drives the pallet to move onto the limit column by a first cylinder to move the chainsaw guide plate to the position of the first clamping plate, and drives the first clamping plate to move closer to each other along the third guide rail by a third cylinder to achieve the limit fixation of the chainsaw guide plate, and then drives the driving shaft to rotate by a first motor, and the driving shaft drives the driven shaft to rotate, and the driven shaft rotates, and the first stirring rotation is achieved through transmission, thereby achieving flipping, and after the flipping is completed, the second cylinder drives the first push rod to drive the first mounting plate to move in the horizontal direction, thereby driving the second mounting plate to move in the horizontal direction, and the fifth cylinder drives the hydraulic piston shaft to extend and retract in the hydraulic piston to achieve the movement of the pallet in the numerical direction, thereby achieving the flipping and transportation operations, thereby achieving the synthesis, flipping and transportation processes of the chainsaw guide plate.

[0004] Although the above scheme integrates the working procedures, it cannot be used for the welding and conveying of the assembled chain saw guide plate. The loading and unloading of the welding machine for welding operation still requires manual operation. Due to manual loading, the operator is at risk of having his hands pinched during the loading process, and safety cannot be guaranteed. In addition, after loading the welding machine, the operator needs to stay away from the welding machine before welding can be carried out, which wastes a lot of time and cannot guarantee production efficiency. Summary of the invention

[0005] The purpose of the utility model is to solve the above problems and provide a guide plate reciprocating conveyor for a chain saw guide plate welding device which has a reasonable design and can improve production safety and ensure production efficiency.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a guide bar reciprocating conveyor of a chain saw guide bar welding device, characterized in that it includes a frame, a horizontally arranged feed trough is provided on the table top of the frame, one end of the feed trough extends to the outside to form an opening, a feed rod is provided in the feed trough, a guide plate bearing surface is provided on the top surface of the feed rod, a guide plate positioning assembly is provided on the guide plate bearing surface, the feed rod and a reciprocating drive mechanism that can drive the feed rod to move axially in the feed trough and move out of the opening to feed the chain saw guide on the guide plate bearing surface to the welding machine for welding and return it to its position after welding is completed.

One end of the feed rod is connected to the reciprocating drive mechanism, and the other end can be extended into the welding machine through the opening for welding. The reciprocating drive assembly drives the feed rod to move back and forth in the feed trough to realize the reciprocating transportation of the chain saw guide plate, so that loading and unloading can be completed away from the welding machine, thereby improving safety and production efficiency.

[0011] In the guide bar reciprocating conveyor of the chain saw guide bar welding device, the lifting stroke limit assembly includes a pin shaft arranged in the lifting movable groove, the lifting plate is provided with at least one vertically arranged strip hole penetrating both sides of the lifting plate, and the pin shaft is inserted into the strip hole. The structure in which the pin shaft is inserted into the strip hole can realize the axial conveyance of the feeding rod and also play the role of lifting limit in the vertical direction.

[0012] In the guide plate reciprocating conveyor of the chain saw guide plate welding device, two lifting limit plates parallel to each other are arranged on one end of the transmission plate, the lifting limit plate is connected to the transmission plate as a whole, and the lifting movable groove is formed between the two lifting limit plates and the transmission plate, and the pin shaft is a bolt and a nut, and the bolt passes through the two lifting limit plates. The pin shaft structure of the bolt and the nut is convenient for installation and disassembly.

[0013] In the guide bar reciprocating conveyor of the chain saw guide bar welding device, a guiding slope is provided between the front end and the bottom surface of the feed rod. The guiding slope guides the feed rod into the welding machine, thereby preventing the feed rod from hitting the strip top plate head-on, thereby entering the welding machine more smoothly.

[0014] In the guide bar reciprocating conveyor of the chain saw guide bar welding device, the guide bar positioning assembly includes a plurality of positioning holes arranged on the guide bar bearing surface and distributed along the axial direction of the feed rod, and two of the positioning holes are provided with detachable and fixed positioning columns. The positioning columns can fix the chain saw guide bar on the feed rod and ensure that the relative position of the chain saw guide bar and the feed rod remains unchanged during each welding.

[0015] In the guide bar reciprocating conveyor of the chain saw guide bar welding device, two horizontally arranged and mutually parallel limiting rods are provided on the table, and the limiting rods are connected to the frame through a spacing adjustment assembly capable of adjusting the spacing between the two limiting rods. The conveying trough is formed by limiting the two limiting rods fixed on the frame, so that the conveying track of the chain saw guide bar can be determined, and the stability of the chain saw guide bar conveying process can be ensured.
