Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of automobile parts machining, especially relates to a tool fixture for automobile part production and machining. BACKGROUND

[0002] The annular automobile parts refer to various parts in the automobile structure, which have a ring shape or an approximate ring shape, and play a key role in different systems of the automobile. For example, the piston ring is an important annular part in the engine, which is generally installed in the ring groove of the piston and mainly has the functions of sealing, oil control and heat conduction, can prevent the gas in the combustion chamber from leaking, control the oil consumption and transmit the heat of the piston to the cylinder wall. Also, the wheel hub of the automobile can be regarded as an annular part, which is the installation base of the tire, supports the weight of the vehicle and bears various forces from the road during the driving of the vehicle, has an important influence on the controllability and stability of the vehicle. In addition, there are some sealing rings and bearing rings, which are also annular automobile parts. The sealing ring is used to prevent liquid or gas from leaking and ensure the normal operation of the cooling system and fuel system of the automobile. The bearing ring provides support and guidance for the rotating parts, reduces friction and ensures the smooth operation of the related parts.

[0003] The Chinese patent with the publication number "CN212444179U" discloses an automobile part tool fixture, which comprises a workbench. A sliding groove is arranged on the inner wall of the workbench. A screw rod is arranged on the inner wall of the sliding groove. A sliding block is mounted on the outer wall of the screw rod. A fixed block is arranged on the outer wall of the screw rod and located on the inner wall of the workbench. A handle is fixed to one end of the screw rod. A sliding block is mounted on the bottom end of the sliding block. A rotary motor is arranged on the inner wall of the sliding block. The utility model places the automobile parts on the base, rotates the handle, and drives the sliding block mounted on the outer wall of the screw rod to slide forward. When the sliding block slides forward, it drives the sliding block fixed to the top end to slide towards the fixed block. Thus, the sliding block and the fixed block fix the automobile parts. The utility model solves the problem that the automobile parts need to be fixed during machining. The workpiece is not fixed firmly, which causes displacement and damages the workpiece and the machining device.

However, the parts of the prior art can only position the outer ring of the annular part. When the outer side of the annular part needs to be machined, it is difficult to flexibly adjust to meet the machining requirements. If the inner side is clamped, it will seriously hinder the machining operation of the inner side. This limitation is very inconvenient in actual production and seriously affects the machining efficiency and quality.

[0029] Working principle and advantages: The device combines the positioning mechanism 2 with the driving mechanism 3. When the device is started, the second motor 34 is turned on, and the motor operation drives the inner bevel gear 32 to rotate. The inner bevel gear 32 meshes with the outer bevel gear 33, driving the outer bevel gear 33 to rotate. The rotation of the outer bevel gear 33 drives the screw rod 22 to work, and the rotation of the screw rod 22 makes the sliding block 23 slide inside the guide rail 21, providing support for subsequent positioning operations.

[0030] During actual processing, the ring-shaped parts to be positioned are placed between the two guide rollers 243, and the outer ring of the ring-shaped parts is clamped. The sliding block 23 drives the positioning assembly 24 to move inward, and the outer guide roller 243 is attached to the outer ring of the ring-shaped parts to achieve clamping. The inner ring of the ring-shaped parts is clamped and positioned, and the sliding block 23 is adjusted to move outward. The sliding block 23 drives the base plate 241 to move outward, and the guide roller 243 at the top inner end of the base plate 241 is attached to the inner side of the ring-shaped parts to achieve clamping of the inner ring of the ring-shaped parts. This design allows the device to adjust the clamping of the inner and outer sides of the ring-shaped parts, improving the device's adaptability and having promotional application value.

[0031] The positioning assembly 24 of the device plays a key role. After the ring-shaped parts are clamped and fixed, the first motor 244 is started, and the motor operation drives the drive gear 245 at the output end to rotate. The drive gear 245 meshes with the transmission gear 246, and the rotation of the drive gear 245 drives the transmission gear 246 to rotate. The bottom of the transmission gear 246 is connected to the top of the guide roller 243, and the rotation of the transmission gear 246 drives the guide roller 243 to rotate at high speed. The rotation of the guide roller 243 makes the ring-shaped parts inside each guide roller 243 rotate. When the ring-shaped parts rotate, the operator can adjust the clamping position of the ring-shaped parts and process the original clamping position. This design allows the device to process the inner and outer surfaces of the ring-shaped parts, avoiding processing dead angles and improving the device's convenience and adaptability, providing protection for the overall processing of ring-shaped parts and improving production efficiency and processing quality.
