Description

Technical Field

[0001] This utility model relates to the field of electromechanical equipment maintenance technology, and in particular to a horizontal disassembly machine with an adjustable chuck. Background Technology

[0002] Because different models of hydraulic cylinders have different cylinder bottom structures, the required hydraulic cylinder base chuck models are also different. In the past, different models of hydraulic cylinders required the corresponding model of base chuck to be machined, which wasted materials, tooling changes, and time, and seriously restricted the production progress. In response, the workshop carried out technical modifications to the small hydraulic cylinder base chuck based on actual production needs. During the maintenance of hydraulic support cylinder components, it is necessary to disassemble the cylinder components. Due to the large number of disassemblies, the small hydraulic cylinder horizontal disassembly and assembly machine is used frequently and can no longer meet production needs. Based on production needs, a small hydraulic cylinder horizontal disassembly and assembly machine was purchased. The newly purchased disassembly and assembly machine did not have a corresponding disassembly and assembly chuck (the manufacturer did not provide the chuck, only the intermediate connecting parts). The workshop employees developed the chuck for the horizontal disassembly and assembly machine based on the actual operation procedures.

[0003] A chuck is a mechanical device used on machine tools to clamp workpieces. Its core function is to position and fix the workpiece through the radial movement of the movable jaws. It consists of a chuck body, movable jaws, and a drive mechanism. The chuck body is usually hollow or solid and connects to the machine tool spindle. The movable jaws are connected to the drive mechanism via threaded or wedge mechanisms. Horizontal disassembly machines are mainly used for disassembling and maintaining horizontal hydraulic cylinders, and are particularly suitable for disassembling and assembling single-telescopic and double-telescopic columns and hydraulic cylinders of fully mechanized coal mining hydraulic supports. This equipment adopts an integral rigid bed, hydraulic clamping mechanism, fast and slow dual-speed slides, and a ratchet rocker arm linked with a high-torque low-speed hydraulic motor. It features high disassembly torque, flexible adjustment of disassembly force, convenient and flexible operation, and electro-hydraulic control.

[0004] The prior art patent CN207104822U discloses a horizontal hydraulic cylinder dismantling machine, including a hydraulic station, a working hydraulic cylinder connected to the hydraulic station via pipeline, and a fixed frame. The fixed frame is a section of H-beam. The working hydraulic cylinder is longitudinally positioned on one side of the upper part of the fixed frame. The working hydraulic cylinder is hinged to lugs fixed to both sides of the fixed frame via a cylinder body pin. The piston rod of the working hydraulic cylinder is hinged to one end of a connecting rocker arm with an I-shaped cross-section via a first pin. The other end of the connecting rocker arm is hinged to a second pin, which is used to connect the piston rod of the hydraulic cylinder to be dismantled. Multiple sets of adjusting guard plates with unequal distances are fixed to the other side of the upper part of the fixed frame. Each set of adjusting guard plates consists of two plates, symmetrically fixed to both sides of the fixed frame. The outer side of the adjusting guard plates is provided with a fixing pin with a horizontal axis for longitudinally fixing the hydraulic cylinder to be dismantled. This utility model dismantling machine is simple to operate, easy to maintain, occupies little space, is easy to maintain, saves time and labor, has a high utilization rate, reduces labor intensity, saves time, reduces costs, and improves production efficiency.

[0005] However, in the daily maintenance of existing jacks, a horizontal disassembly and assembly machine is required to disassemble and assemble the hydraulic cylinders. Due to the large number of disassemblies and assemblies, the horizontal disassembly and assembly machine for small hydraulic cylinders is used frequently and can no longer meet production needs. In addition, the chuck cannot be replaced according to the requirements, which is not flexible enough. Utility Model Content

[0006] To overcome the shortcomings in the development of chucks in existing horizontal dismantling machines, which prevent the replacement of chucks of different sizes according to requirements and lack of flexibility.

[0007] The technical solution of this utility model is as follows: a horizontal disassembly machine with an adjustable chuck, including a horizontal disassembly machine body and a chuck body. The chuck body is provided at the front end of the horizontal disassembly machine body. The four end feet of the front end face of the horizontal disassembly machine body are fixedly connected with positioning protrusions. Positioning grooves are opened between the four positioning protrusions. The four end feet outside the chuck body are fixedly connected with positioning plates that are inserted into the four positioning grooves. The horizontal disassembly machine body and the chuck body are fixed together by eight bolts. High-strength springs are sleeved on the outside of the eight bolts.

[0008] Preferably, the chuck body is installed on the horizontal dismantling machine body and fixed with eight M-type high-strength bolts. The bolts not only have a fixing function but also a guiding function. Each bolt is fitted with a high-strength spring, which acts as a buffer during dismantling and protects the guide sleeve and tooling. The chuck body is made of Q high-strength steel plate as the main material. The fixing tooling can be replaced according to the size of the guide sleeve. It can meet the dismantling and assembly operations of all sizes of jacks except for the column of the hydraulic support.

[0009] Preferably, the surface of the chuck body is provided with a fixing groove, and a mounting plate is engaged inside the fixing groove. Through the engagement between the mounting plate and the fixing groove, the function of disassembling and replacing the fixed tooling is completed.

[0010] Preferably, the front end of the mounting plate is fixedly connected to a fixing fixture, and the fixing fixture has a slot inside for fixing the disassembled hydraulic cylinder.

[0011] Preferably, both the upper and lower ends of the mounting plate and the front surface of the chuck body are fixed by fixing plates.

[0012] Preferably, the horizontal dismantling machine body has an internal mounting slot, into which the chuck body is inserted.

[0013] As a preferred option, the chuck body is made of Q high-strength steel plate, and the bolts are of type M, which serve as guides and fixes.

[0014] Preferably, the rear end face of the chuck body is provided with multiple evenly arranged guide sleeves that are fitted over the bolts.

[0015] The beneficial effects of this utility model are:

[0016] This adjustable chuck horizontal dismantling machine is assembled by attaching the chuck body to the machine body and securing it with eight M-type high-strength bolts. These bolts not only provide fixation but also act as guides. Each bolt is fitted with a high-strength spring, which acts as a buffer during dismantling, protecting the guide sleeve and tooling. The chuck body is constructed primarily of Q-grade high-strength steel plate. The fixing tooling can be replaced according to the guide sleeve size. It can meet the dismantling and assembly needs of all sizes of jacks (excluding the column) for hydraulic supports. The development and implementation of this horizontal dismantling machine chuck has solved practical problems in production, effectively improving production efficiency. The buffer device incorporated during dismantling and assembly effectively protects the guide sleeve from damage during the dismantling process, making it highly valuable for widespread application.
