Description

Technical Field

[0001] The invention relates to the field of automobile parts processing, in particular to a universal composite seat plate for a gear grinding machine. Background Art

[0002] Automobile refers to a means of transport that uses fuels such as gasoline, diesel, natural gas, or new energy sources such as batteries and solar energy and is powered by an engine. It is a vehicle that generally has four or more wheels and travels on land without relying on tracks or wires. Automobiles are usually used to carry passengers and goods and to tow passenger and cargo trailers. Some are modified or equipped with special equipment to complete specific transportation tasks or work tasks, but do not include machinery used exclusively in agriculture. Automobile license plates have the function of identifying and marking automobiles.

[0003] In the process of automobile manufacturing, the tooth structure accounts for a large proportion of the various parts that constitute the automobile. For example, gearboxes, synchronizers, transfer cases, drive axles, etc., all involve the application of gear structures. At present, gear parts are usually processed by gear grinding machines during the processing process. Before sending the gear parts into the gear grinding machine for processing, it is necessary to install corresponding tooling on the gear grinding machine to fix the corresponding workpiece. The gear parts include the processing of disc structures and the processing of shaft structures. At present, for the processing of these two different structural forms of workpieces, two different sets of tooling are required for fixing. When replacing the tooling, the original tooling needs to be removed from the gear grinding machine and then the new tooling is installed, which is very troublesome and the work efficiency is not high. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a universal composite seat disc for a gear grinding machine which is easy to replace and has high working efficiency.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: a universal composite seat plate for a gear grinding machine, the innovation of which is: comprising

[0006] A base, the base comprising a processing base and a fixed base which are sequentially arranged in the upper and lower parts, the processing base and the fixed base being connected via a detachable structure, the processing base and the fixed base both being in an inverted T shape, and the bottom end of the processing base being in contact with the top end of the fixed base;

[0007] An axial processing assembly disposed on the processing base, the axial processing assembly comprising an ejector pin, the ejector pin being disposed in the middle of the processing base, the tail end of the ejector pin being disposed in the processing base, and the needle head of the ejector pin extending from the bottom end of the processing base;

[0008] A wheeled processing assembly is arranged on a processing base, and the wheeled processing assembly includes a limit ring, a fixed seat, and a pressure plate. The limit ring is sleeved on the outside of the processing base and fixed to the bottom of the processing base. The fixed seat is in an inverted T shape. The bottom end of the fixed seat is fixed to the top end of the processing base by screws, and the ejector pin is placed in the fixed seat. The upper position of the fixed seat also has an external thread structure. The pressure plate is sleeved on the fixed seat and locked by a locking nut.

[0009] Furthermore, the disassembly structure is as follows: the bottom end of the processing base is consistent with the size of the top end of the fixed base, and a plurality of inverted T-shaped connecting grooves distributed along the circumferential direction of the fixed base are opened at the top end of the fixed base, and at the same time, there are T-shaped connecting through holes on the processing base that are connected to the connecting grooves one by one, and a matching inverted T-shaped connecting block is embedded in each connecting groove, and a threaded connecting hole is also opened on the connecting block, and a T-shaped bolt is arranged in each connecting through hole, and the T-shaped bolt is threadedly matched with the threaded connecting hole of the connecting block, thereby realizing the fixation between the processing base and the fixed base.

[0010] Furthermore, a groove is provided at the joint between the processing base and the fixed base.

[0011] The advantages of the present invention are: the composite chassis of the present invention adopts the cooperation between the base, the shaft processing assembly and the wheel processing assembly, so as to realize the tooth processing of the disc gear and the shaft gear on the same chassis without replacing the entire base, which is very convenient and the corresponding work efficiency is also improved.

[0012] For the design of the detachable structure, the connection grooves, connection through holes, connection blocks and bolts are used to cooperate with each other, so as to realize the movable fixation between the processing base and the fixed base. In the subsequent maintenance, the fixed base can be removed separately for easy maintenance.

[0013] The design of the groove at the joint between the processing base and the fixed base reduces the contact area between the processing base and the fixed base, reduces the plane processing accuracy requirements of the contact surfaces of the two, and reduces production costs.

[0023] The following embodiments can enable those skilled in the art to more fully understand the present invention, but the present invention is not limited to the scope of the embodiments.

[0024] like Figure 1-Figure 8 A universal composite seat plate for a gear grinding machine shown in the figure comprises

[0025] A base, the base includes a processing base 2 and a fixed base 1 which are distributed in sequence from top to bottom. The processing base 2 and the fixed base 1 are similar in shape, both of which are inverted T-shaped structures composed of a cylindrical section at the upper end and a disc section at the bottom end, and the bottom end of the disc section of the processing base 2 fits with the top end of the cylindrical section of the fixed base 1, and the size of the bottom end of the disc section of the processing base is consistent with the size of the top end of the cylindrical section of the fixed base. The interiors of the processing base 2 and the fixed base 1 are both hollow structures, and through holes connected to the internal cavity are opened at the bottom ends of the processing base 2 and the fixed base 1, and several connecting through holes are also opened on the disc section of the fixed base 1.

[0026] A groove 3 is also provided at the joint of the processing base 2 and the fixed base 1. The design of the groove 3 at the joint of the processing base 2 and the fixed base 1 reduces the contact area between the processing base 2 and the fixed base 1, reduces the plane machining accuracy requirements of the contact surface between the two, and reduces the production cost.

[0027] The processing base 2 is connected to the fixed base 1 through a detachable structure, and the detachable structure is as follows: a plurality of inverted T-shaped connecting grooves 11 distributed along the circumferential direction of the fixed base 1 are opened at the top of the fixed base 1, and at the same time, a T-shaped connecting through hole 12 corresponding to the connecting groove 11 is provided on the processing base 2, and a matching inverted T-shaped connecting block is embedded in each connecting groove 11, and a threaded connecting hole is also opened on the connecting block, and a T-shaped bolt is arranged in each connecting through hole 12, and the T-shaped bolt is threadedly matched with the threaded connecting hole of the connecting block. When fixing, first, the inverted T-shaped connecting block is embedded in each inverted T-shaped connecting groove 11 until the threaded connecting hole on the connecting block is aligned with the T-shaped connecting through hole 12, and then the T-shaped bolt is embedded from the connecting through hole 12 and threadedly connected with the connecting block, thereby realizing the fixation between the processing base 2 and the fixed base 1. For the design of the detachable structure, the connection groove 11, the connection through hole 12, the connection block and the bolt are matched to achieve the movable fixation between the processing base 2 and the fixed base 1. In the subsequent production, if the base needs to be maintained, the fixed base 1 can be removed separately, so as to facilitate maintenance.

[0028] An axial processing assembly is arranged on the processing base 2, and the axial processing assembly includes an ejector pin 21, which is arranged in the middle of the processing base 2, and the tail end of the ejector pin 21 is arranged in the processing base 2, and the needle head of the ejector pin 21 extends from the bottom end of the processing base 2.

[0029] A wheeled processing assembly is provided on the processing base 2, and the wheeled processing assembly includes a limit ring 31, a fixed seat 32, and a pressure plate 33. The limit ring 31 is sleeved on the outside of the cylindrical section of the processing base 2 and fixed on the upper surface of the disc section of the processing base 2. The fixed seat 32 is also an inverted T-shaped structure consisting of an upper cylindrical section and a lower disc section. The bottom end of the disc section of the fixed seat 32 is fixed to the top end of the cylindrical section of the processing base 2 by screws, and when the fixed seat 32 is fixed on the processing base 2, the ejector pin 21 is completely placed in the fixed seat 32. At the same time, there is a cavity in the fixed seat 32 for accommodating the ejector pin 21 to be embedded. The cylindrical section of the fixed seat 32 also has an external thread structure, and the pressure plate 33 is sleeved on the outside of the cylindrical section of the fixed seat 32, and is locked by a locking nut after the pressure plate 33 is sleeved on the outside of the cylindrical section of the fixed seat 32.

[0030] Working principle: When machining the tooth structure of shaft gears, no wheel machining components are installed on the machining base 2, such as Figure 1 As shown, the ejector pin 21 is directly used to press against the bottom end of the shaft gear, and the top end of the shaft gear is then pressed by other pressing components, thereby achieving the positioning and fixing of the shaft gear, so as to facilitate the subsequent processing of the shaft gear by a gear grinding machine.

[0031] When processing the tooth structure of a disc gear, a wheel processing assembly is installed on the processing base 2, such as Figure 5 As shown, the disc gear is mounted on the outside of the processing base 2, and the bottom end of the disc gear is supported on the upper surface of the disc segment of the processing base 2, and then the pressure plate 33 is pressed on the upper segment of the disc gear, and the locking nut is threadedly matched with the cylindrical segment of the fixing seat 32, so that the pressure plate 33 is pressed against the disc gear to achieve the positioning and fixation of the disc gear, so as to facilitate the subsequent processing of the disc gear using a gear grinding machine.
