Description

Technical Field

[0001] This utility model relates to the field of deburring technology for cylindrical automotive parts, and more specifically, it relates to a deburring positioning structure for processing cylindrical automotive parts. Background Technology

[0002] In the deburring process of cylindrical automotive parts, it is necessary to reliably clamp the cylindrical workpiece and maintain its positional stability during the processing. Traditional manual adjustment fixtures require operators to adjust the position of multiple jaws one by one according to the diameter of the workpiece. The adjustment process is cumbersome and time-consuming, and it is difficult to ensure that multiple clamping points tighten synchronously and that the clamping force is evenly distributed. Some jaws may be too tight, causing indentations on the workpiece surface, while some jaws may be too loose, resulting in insecure clamping. Frequent manual adjustments seriously affect production efficiency.

[0003] The reliability and ease of operation of existing locking methods are difficult to balance. Although traditional threaded locking has high locking strength, it requires tightening the locking nut with a wrench after each clamping and loosening the nut to remove the workpiece after processing. This operation is cumbersome, time-consuming and labor-intensive, which seriously restricts processing efficiency and continuous operation capability. In addition, traditional locking methods lack automatic positioning and anti-misoperation mechanisms, and inaccurate locking or incomplete locking often occurs. Unlocking is also not convenient enough, and it is impossible to quickly load and unload workpieces. It is difficult to meet the requirements of high-efficiency and high-reliability positioning and clamping in modern automotive parts processing, which limits the overall efficiency and processing quality stability of deburring. Utility Model Content

[0004] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a deburring positioning structure for processing cylindrical automotive parts, so as to solve the technical problems mentioned in the background art.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a deburring and positioning structure for processing cylindrical automotive parts, comprising a grinding machine and a fixing sleeve. An mounting cylinder is fixedly mounted on the grinding machine, and the fixing sleeve is fixed to the top of the mounting cylinder. A sliding rod is fixedly mounted inside the fixing sleeve. Multiple sets of sliding rods are provided, each with a sliding block on its outer wall. Mounting blocks are fixedly mounted inside each set of sliding blocks. Compression springs are connected to the inner sides of each set of mounting blocks. Multiple sets of compression springs are provided, each with a clamping plate fixed at its bottom end. A sliding groove is provided on the outer wall of the fixing sleeve. Multiple sets of sliding grooves are provided and slidably connected to a sliding sleeve. A push ring is fixedly mounted inside the sliding sleeve, and the push ring abuts against the bottom surface of the multiple sets of mounting blocks. An arc-shaped rod is fixedly mounted on the outer wall of the sliding sleeve. Multiple sets of arc-shaped rods are provided. A rotating sleeve is rotatably mounted on the outer wall of the fixing sleeve. A limiting rod is fixedly mounted on the outer wall of the rotating sleeve. Multiple sets of limiting rods are provided, each with a limiting hole on its outer wall.

[0006] The present invention is further configured such that a reset spring is connected to the inner wall of the fixed sleeve, and an abutment ring is fixedly provided at the bottom end of the reset spring. The abutment ring abuts against the top surface of multiple sets of mounting blocks. The reset spring provides reset elasticity for the mounting blocks, realizing the automatic reset and quick unlocking function of the clamping plate, and improving the workpiece loading and unloading efficiency.

[0007] The present invention is further provided in that rubber pads are fixedly provided on the inner side of each of the multiple sets of clamping plates. The rubber pads provide high friction clamping and prevent damage to the workpiece surface, while absorbing processing vibrations, thereby improving the stability of clamping and the surface protection performance of the workpiece.

[0008] The present invention is further configured such that guide grooves are provided on the inner sides of the multiple sets of mounting blocks, and guide blocks are fixedly provided on the outer walls of the multiple sets of clamping plates. The multiple sets of guide blocks slide in the multiple sets of guide grooves respectively. The cooperation between the guide blocks and the guide grooves ensures that the clamping plates move accurately in the radial direction, avoids clamping offset, and improves clamping accuracy and reliability.

[0009] The present invention is further configured such that multiple sets of sliding rods are inclinedly arranged inside the fixed sleeve and have sliding strips fixed on the outer side. Multiple sets of sliding strips are provided and are slidably connected to multiple sets of sliders respectively. The inclined sliding rods achieve mechanical force amplification and synchronous tightening through the cooperation of the sliding strips and sliders, ensuring that the clamping force of multiple sets of clamping plates is evenly distributed, and improving the synchronicity and stability of clamping.

[0010] The present invention is further configured such that a guide rod is fixedly provided inside the fixed sleeve, and multiple sets of guide rods are provided, all of which are slidably connected to the push ring. The guide rods provide precise sliding guidance for the push ring, preventing the push ring from deviating or getting stuck, and ensuring the smoothness and reliability of the pushing process.

[0011] The present invention is further configured such that a sliding hole is provided on the inner side of the rotating sleeve, and multiple sets of sliding holes are provided, each of which is connected to a push spring. A positioning block is fixed at the bottom end of each set of push springs. A positioning groove is provided on the outer wall of the fixed sleeve, and multiple sets of positioning grooves are provided, each of which abuts against a set of positioning blocks. The push springs automatically push the positioning blocks to abut against the positioning grooves, thereby realizing the automatic positioning and locking of the rotating sleeve, preventing accidental rotation, and improving the reliability and convenience of locking.

[0012] The present invention is further configured such that the bottom ends of the multiple sets of positioning blocks and the outer sides of the positioning grooves are all arc-shaped. The arc-shaped design reduces the resistance when the positioning blocks enter and exit the positioning grooves, realizes smooth positioning and unlocking operations, and improves the convenience and smoothness of operation.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides a deburring positioning structure for processing cylindrical automotive parts, which has the following advantages: 1. After the operator inserts cylindrical workpieces of different diameters into the fixed sleeve, the operator pushes the sliding sleeve to drive the push ring to slide along the guide rod and push multiple sets of mounting blocks. The multiple sets of mounting blocks slide inward synchronously along the inclined sliding rod through the slider, so that the multiple sets of clamping plates automatically adapt to the workpiece diameter under the action of the compression spring and clamp evenly on the outer wall of the workpiece. Compared with the traditional method that requires manual adjustment of the position of multiple jaws one by one, this push-type synchronous clamping structure can drive multiple sets of clamping plates to tighten synchronously with a single push operation. The mechanical force amplification effect of the inclined sliding rod ensures the uniform distribution of clamping force. There is no need to pre-adjust according to the workpiece diameter, which significantly simplifies the operation process and greatly shortens the clamping time.

[0014] 2. This utility model achieves synchronous tightening and uniform distribution of clamping force through multiple sets of clamping plates under the action of inclined slide bars. Compared with the complex systems driven by traditional pneumatic or hydraulic systems, this purely mechanical structure does not require auxiliary equipment such as air sources or hydraulic stations, reducing equipment costs and maintenance difficulty. It prevents workpiece surface indentations or loosening caused by uneven clamping force, ensuring the stability of the workpiece position during processing, and meeting the needs of small and medium-sized processing enterprises for simple, efficient and cost-controllable positioning devices.

[0015] 3. This utility model achieves the limiting and locking of the sliding sleeve by rotating the rotating sleeve to insert the arc-shaped rod into the limiting hole. The push spring automatically pushes the positioning block to abut against the positioning groove for precise positioning of the rotating sleeve. Compared with the traditional locking method that requires a wrench to tighten the lock nut, this rotating plug-in locking structure can complete the locking with a single rotation operation. The arc-shaped design of the positioning block and the positioning groove reduces the positioning resistance and realizes the automatic positioning function of the rotating sleeve. When unlocking, rotating the rotating sleeve in the opposite direction can push the positioning block to disengage through the positioning groove and disengage the arc-shaped rod from the limiting hole. The return spring automatically pushes the abutment ring to reset and release the clamping. While ensuring high locking strength and anti-loosening reliability, it achieves fast locking and unlocking, meeting the requirements of modern automotive parts processing for high-efficiency and high-reliability positioning and clamping, and comprehensively improving the overall efficiency and processing quality stability of deburring.
