Description

Technical Field

[0001] The present invention relates to the technical field of vehicle tire disassembly and assembly, and particularly to an integrated workbench for a tire changer with a gearbox. Background Art

[0002] With the development of automation, the degree of automation of tire changing is getting higher and higher, and there are more and more workbenches without a large disk. This is because it is convenient for the tire removal hook to automatically remove the tire. However, looking around the world, most tire fixings still remain in the manual locking state, with heavy and slow fixing parts, and the locking mechanisms are all built-in. People dare not use pneumatic locking for tires because they are afraid of power failure of the equipment, mechanical failures or lack of power in the built-in cylinders, and the tires locked on the tire changer cannot be taken out, resulting in a very helpless situation. At present, the problem of inconvenient tire disassembly in case of emergency has become an urgent problem to be solved in this industry. Some hydraulic tire changers on the market have high manufacturing costs, slow speeds, hydraulic leakage and noise, resulting in a poor working environment. Therefore, it is particularly important to solve the problem that ordinary tire changers cannot work under special pneumatic control conditions and have a relatively single transmission structure. Summary of the Invention

[0003] The purpose of the present invention is to provide an integrated workbench for a tire changer with a gearbox. Since both the cylinder and the locking mechanism are external, it has a high degree of automation, is safe and convenient, without any worries. It can quickly clamp the tire, can easily cope with sudden power outages and air cuts, and avoid mechanical failures. As long as the spring collet A in the head of the smooth rod is loosened with an Allen key, the tire fixed on the tire changer can be easily removed. At the same time, two structures are extended by applying two transmission methods of belt drive and gear drive, solving the problem that ordinary tire changers cannot work under special pneumatic locking conditions and have a relatively single transmission structure.

[0004] The present invention provides an integrated workbench for a tire changer with a gearbox, including a workbench, on which a quick-release nut, a positioning optical axis, a spring collet A, a steel ball, an upper spring, a clamping piece, a spring collet B, a push rod, a main shaft, a tire mounting disc and a positioning pin are arranged. The quick-release nut is arranged at the upper end of the positioning optical axis, the spring collet A is arranged in the upper part of the positioning optical axis, the spring collet B is arranged in the lower part of the positioning optical axis, the upper spring is installed between the spring collet A and the spring collet B, the steel ball is arranged in the upper spring, the push rod is arranged at the lower end of the positioning optical axis, the main shaft is arranged at the lower end of the push rod, the tire mounting disc is arranged between the positioning optical axis and the push rod, the positioning pin is arranged on the tire mounting disc, and the tire is mounted on the tire mounting disc.

[0005] Further improvement lies in that: a positioning cone block is arranged above the tire mounting disc, a plastic part is arranged at the upper end of the positioning cone block, and a locking sleeve is arranged outside the positioning optical axis. The tire on the tire mounting disc is fixed through the cooperation of the positioning cone block, the plastic part, the locking sleeve and the quick-release nut.

[0006] A further improvement lies in that: an upper bearing is provided on the upper part of the main shaft, a lower bearing is provided on the lower part of the main shaft, an outer sleeve is provided outside the main shaft, and the outer sleeve is fixed to the workbench through a fixing bolt assembly.

[0007] A further improvement lies in that: the ejector rod is sleeved with a lower spring, and a resilient force is applied to the ejector rod through the lower spring.

[0008] A further improvement lies in that: a gearbox is provided below the main shaft, the main shaft is driven by the gearbox, and the gearbox is divided into two working structures: belt drive and gear drive.

[0009] A further improvement lies in that: the gearbox with belt drive includes a gearbox main shaft, a turbine, a worm, a pulley, an upper gearbox cover, a lower gearbox cover, a belt and a motor. The motor is connected to the pulley through the belt. The gearbox main shaft is connected to the main shaft through a spline. The gearbox main shaft is connected to the turbine, and the turbine meshes with the worm. The pulley is arranged on the worm. The gearbox main shaft, the turbine, the worm and the pulley are arranged in the space formed by the upper gearbox cover and the lower gearbox cover. The upper gearbox cover is connected to the workbench through fixing bolts.

[0010] A further improvement lies in that: the gearbox with gear drive includes a gearbox main shaft, a large gear, an inclined gear shaft, a middle gear, an upper gearbox cover, a lower gearbox cover, an inclined gear and a motor. The motor is connected to the inclined gear. The inclined gear is arranged on the inclined gear shaft. The inclined gear meshes with the middle gear, and the middle gear meshes with the large gear. The large gear is installed on the gearbox main shaft. The gearbox main shaft, the large gear, the inclined gear shaft and the middle gear are arranged in the space formed by the upper gearbox cover and the lower gearbox cover. The upper gearbox cover is connected to the workbench through fixing bolts.

[0011] A further improvement lies in that: a cylinder is provided at the lower end of the ejector rod, and the ejector rod is driven to move up and down by the cylinder.

[0012] A further improvement lies in that: a cylindrical pin is provided at the lower end of the lower spring, and a tire protection plastic pad is provided on the tire mounting disc.

[0013] A further improvement lies in that: a bearing gland is provided on the upper bearing, the bearing gland is installed and fixed through bearing gland bolts. The tire mounting disc is connected to the outer sleeve through mounting disc fixing bolts, and the tire mounting disc has anti-rotation pins.

[0014] Advantages of the present invention: Since both the external cylinder and the locking mechanism are external, the automation level is high, and it is safe and convenient without any worries. For both types of speed changes, the output main shaft of the gearbox is made into a hollow main shaft, with a cylinder installed below. Through the ejector rod, the compression spring is pushed to generate pressure to automatically clamp the tire; since this set of mechanisms utilizes the external cylinder, the spring collet A, steel balls, springs, and clip pieces inside the positioning optical rod, the spring collet B, and then cooperates with the locking sleeve and the quick-release lock nut, this set of locking mechanisms, both the head and the tail are external devices, which can quickly clamp the tire, can easily handle sudden power outages and air outages, and avoid mechanical failures. As long as the spring collet A inside the head of the optical rod is loosened with an internal hexagon wrench, the tire fixed on the tire changer can be easily removed; the spring inside the main shaft of the workbench is a flat spring for the outer circle, the positioning optical rod is flange-connected to the main shaft, and there is a set of steel ball locking mechanisms inside, and three steel balls are used to improve the stability of locking and positioning.

[0015] The automation level of clamping the tire is improved; boldly using the convenient air source has ended people's fear of pneumatically clamping the tire; an integrated gearbox can be used, combined with a diskless workbench, to make a 90° rotatable workbench of the tire changer, further improving the automation level, and the cost is much lower than that of a hydraulic tire changer.
