Description

Technical Field

[0001] This utility model relates to the field of scope accessory processing technology, and in particular to a polishing device for scope accessory processing. Background Technology

[0002] Traditional polishing of scope components relies on workers using handheld power tools. Operators must manually control the contact position and pressure of the polishing wheel on the workpiece throughout the process. Long-term operation leads to worker arm fatigue and tremors, making it difficult to guarantee the consistency of processing. Especially for curved or irregularly shaped workpieces, manual operation is prone to uneven polishing or over-polishing of edges and corners, and the dust environment poses a continuous threat to human health. The core contradiction of this mode is that it is highly dependent on human experience and physical strength, making it difficult to balance efficiency and accuracy.

[0003] To overcome the limitations of manual labor, the industry adopts an automated dual-axis positioning structure driven by a motor. Specifically, the polishing wheel is connected to a vertically oriented lead screw lifting mechanism via a bracket, with its height controlled by a lifting motor. The workpiece is mounted on a horizontally arranged translation slide, and its distance from the polishing wheel is adjusted by a translation motor. By linking the dual-axis motion through a preset trajectory program, the polishing path is mechanically reproduced. This solution replaces manual operation with electromechanical collaboration, significantly reducing labor intensity and improving the accuracy of repetitive processing.

[0004] However, the automated structure exposes the fundamental flaws of the polishing wheel fixing method during operation. The current mainstream method directly inserts the polishing wheel's center hole into the motor drive shaft and then fixes it with a single locking nut screwed from the shaft end. This type of structure exhibits dual limitations under high-speed rotation and directional load conditions: on the one hand, the clearance fit between the center hole and the drive shaft lacks radial constraint, and the polishing wheel is prone to slight wobble when the workpiece surface pressure changes abruptly, resulting in undulating textures on the polished surface; on the other hand, single-point threaded locking is difficult to resist continuous vibration and impact, and the nut is prone to loosening, causing the polishing wheel to move axially, which may weaken the effective contact pressure or even cause the wheel to fall off, resulting in a safety accident. The structural shortcomings of the existing fixing mode, which has weak resistance to dynamic loads, urgently need to be overcome through a multi-directional collaborative constraint mechanism. Utility Model Content

[0005] The purpose of this utility model is to provide a polishing device for processing scope accessories, which solves the problems of radial runout and axial loosening of the polishing wheel caused by the use of a central hole sleeve shaft fit and a single nut locking structure in existing automated polishing equipment.

[0006] To achieve the above objectives, this utility model provides a polishing device for processing scope accessories, including a polishing wheel. The polishing wheel has a groove at its top end, a slot in the middle of the groove, and four positioning holes spaced apart outside the slot in the groove. A retaining plate is embedded in the groove, and a screw is fixedly installed in the middle of the bottom end of the retaining plate. Four positioning pins are spaced apart outside the screw at the bottom end of the retaining plate. After the retaining plate is embedded in the groove, the positioning pins are respectively inserted into the positioning holes, and the screw passes through the bottom of the slot. A nut is threaded onto the bottom end of the screw.

[0007] The card plate passes through the L-shaped plate via a shaft and is connected to the output end of the drive motor. The drive motor is mounted on the top of the L-shaped plate with bolts, and the other end of the L-shaped plate is mounted on the first internal thread block with bolts.

[0008] The first internal threaded block is symmetrically equipped with first sliding clamps on both sides, and the first sliding clamps are slidably mounted on the first slide rail. The first slide rail is symmetrically mounted on both sides of the first slide table, and the first threaded rod is installed inside the first slide table through a bearing.

[0009] The first threaded rod is threadedly engaged with the first internal threaded block. One end of the first threaded rod extends through the first slide and connects to the output end of the first motor. The first motor is mounted on the outside of the first slide by bolts.

[0010] The first slide is bolted to one side of the support column, a fixing plate is fixedly installed at the bottom of the support column, the fixing plate is bolted to one side of the top of the support platform, a storage box is fixedly installed at the bottom of the support platform, and support legs are fixedly installed at the four corners of the bottom of the storage box.

[0011] The support platform is bolted to the top of the fixed plate and a second slide is installed on the top of the second slide. The top of the second slide is symmetrically mounted on the two sides of the second slide, and the outer side of the second slide is slidably mounted with a second sliding clamp.

[0012] The second sliding clamp is symmetrically installed on both sides of the second internal thread block. A support block is bolted to the top of the second internal thread block. A C-shaped plate is bolted to the top of the support block. A rotating motor is bolted to the top surface inside the C-shaped plate.

[0013] The output end of the rotating motor is connected to the rotating disk after passing through the top surface of the C-shaped plate via a shaft. The rotating disk is located at the top of the C-shaped plate and has several fixing holes symmetrically opened at the top of the rotating plate. A second threaded rod is installed in the middle of the second internal threaded block via a thread.

[0014] The two ends of the second threaded rod are mounted inside the second slide table via bearings. One end of the second threaded rod extends and penetrates into the second slide table and is connected to the output end of the second motor. The second motor is mounted on the outside of the second slide table via bolts.

[0015] This utility model discloses a polishing device for processing scope accessories. Through the coordinated action of a groove structure at the top of the polishing wheel and its internal slots and circumferential positioning holes, a multi-level constraint system is formed with a screw and positioning pin fixedly installed at the bottom of a clamping plate embedded in the groove. When the clamping plate is embedded in the groove, the positioning pin precisely inserts into the positioning hole to achieve radial limiting. Simultaneously, after the screw passes through the slot, it is tightened by a nut with a threaded connection at the bottom, making the clamping plate and polishing wheel a rigid connection body that resists torsion and sway. The clamping plate is connected to the output end of the drive source via a shaft. During power transmission, the positioning pin resists circumferential shear force, and the screw and nut form an axial counter-locking mechanism, eliminating radial micro-sway and axial movement of the polishing wheel under high-speed rotation conditions. This structure expands the central support to bear the load across the entire end face of the groove, significantly improving load stability. Multiple mechanical interlocks ensure zero loosening of the connection under variable loads, ultimately achieving the dynamic rigidity and operational safety required for high-precision polishing.

[0023] Please see Figures 1-4 .

[0024] This utility model provides a polishing device for processing scope accessories. The polishing wheel 101, as the core component directly performing polishing, has a groove 102 machined at its top. A slot 103 penetrating the bottom is opened at the center of the groove 102. Four positioning holes 104 are arranged at intervals around the slot 103 within the groove 102. A clamping plate 105 is embedded in this groove 102. A screw 106 is vertically fixedly installed at the center of the bottom end of the clamping plate 105. Four positioning pins 107 are fixedly installed at intervals around the screw 106 at the bottom end of the clamping plate 105. During assembly, the four positioning pins 107 are respectively inserted into the positioning holes 104 in the groove 102 to achieve circumferential positioning. Simultaneously, the screw 106 penetrates the slot 103 and extends out of the bottom of the polishing wheel 101. The bottom end of the screw 106 is secured to the clamping plate 105 on the polishing wheel 101 by a threaded nut 108. An upwardly extending shaft of the clamping plate 105 penetrates the middle of an L-shaped plate 109. This shaft transmits rotational power to the clamping plate 105. The top of the L-shaped plate 109 is fixed to the top of the first internal threaded block 111 by bolts. The output end of the drive motor 110 is connected to this shaft to drive the polishing wheel 101 to rotate. The end of the L-shaped plate 109 away from the clamping plate 105 is fixed to the top surface of the first internal threaded block 111 by bolts. The first sliding clamps 112 are symmetrically installed on both sides of the first internal threaded block 111. The two first sliding clamps 112 are respectively slidably clamped on the first slide rails 113 symmetrically installed on both sides of the first slide table 114. The first threaded rod 115 is horizontally supported by bearings inside the first slide table 114. The first threaded rod 115 meshes with the threaded hole of the first internal threaded block 111. One end of the first threaded rod 115 extends through the end face of the first slide table 114 and is connected to the output shaft of the first motor 116 through a coupling. The first motor 116 is fixed to the outside of the first slide table 114 by bolts. When the first motor 116 is running, it drives the first threaded rod 115 to rotate, forcing the first internal threaded block 111 to make vertical lifting and lowering movements along the first slide rail 113.

[0025] One side of the support column 117 supporting the vertical motion mechanism is bolted to the first slide table 114. The bottom end of the support column 117 is fixedly installed with a fixing plate 118. The fixing plate 118 is firmly installed on one side of the top of the support platform 119 with bolts. The bottom end of the support platform 119 is fixedly connected to a storage box 120 with an open top for collecting polishing debris. The four corners of the bottom end of the storage box 120 are equipped with support feet 121 to provide overall support. The area adjacent to the top of the support platform 119 and the fixing plate 118 is horizontally installed with bolts to the second slide table 122. The top two sides of the second slide table 122 are symmetrically fixed with second slide rails 123. A second sliding clamp 124 is slidably installed on each second slide rail 123. The two second sliding clamps 124 are symmetrically fixed on both sides of the second internal thread block 125, so that the second internal thread block 125 can move laterally along the second slide rail 123. The second internal threaded block 125 has a support block 126 vertically mounted on its top end via bolts. The top end of the support block 126 is horizontally fixed to the C-shaped plate 127 via bolts. A rotating motor 128 is vertically mounted on the inner top surface of the C-shaped plate 127 via bolts. The output end of the rotating motor 128 passes through the inner top surface of the C-shaped plate 127 via a shaft and is directly connected to the bottom center of the rotating disk 129, driving the rotating disk 129 to rotate horizontally above the C-shaped plate 127. Several fixing holes 130 are symmetrically opened on the rotating disk 129 located at the top of the C-shaped plate 127 for mounting a special clamp for holding scope accessories via bolts. The second threaded rod 131 is screwed into the threaded hole of 125. The two ends of the second threaded rod 131 are horizontally supported by bearings on the inner side wall of the second slide table 122. One end of the second threaded rod 131 extends through the side wall of the second slide table 122 and is connected to the output shaft of the second motor 132 through a coupling. The second motor 132 is fixed to the outside of the second slide table 122 by bolts. When the second motor 132 drives the second threaded rod 131 to rotate, it precisely controls the second internal threaded block 125 to drive the support block 126, C-shaped plate 127, rotating motor 128 and rotating disk 129 to move laterally as a whole, so as to realize the position adjustment of the workpiece relative to the polishing wheel 101.

[0026] Working principle: When the device is started, the clamping plate 105 first embeds into the groove 102 at the top of the polishing wheel 101. The positioning pin 107 at the bottom of the clamping plate 105 is inserted into the positioning hole 104 in the groove 102. At the same time, the screw 106 passes through the slot 103 in the middle of the groove 102, and the bottom end is fixed by tightening the nut 108 with a thread, ensuring a stable connection between the clamping plate 105 and the polishing wheel 101, avoiding vibration or displacement during the polishing process, and improving processing stability. The other end of the clamping plate 105 is connected to the L-shaped plate 109 through a shaft. The drive motor 110 is fixed to the top of the L-shaped plate 109 and drives the clamping plate 105 to rotate the polishing wheel 101, thereby providing active polishing power and achieving uniform surface grinding of the parts. The L-shaped plate 109... The other end is fixed to the first internal threaded block 111 by bolts. The two sides of the first internal threaded block 111 are slidably mounted on the first slide rails 113 on both sides of the first slide table 114 via the first sliding clamps 112. The first slide table 114 is equipped with a first threaded rod 115, which forms a threaded engagement with the first internal threaded block 111. When the first motor 116 drives the first threaded rod 115 to rotate, the first internal threaded block 111 moves vertically up and down along the first slide rails 113, thereby driving the entire L-shaped plate 109, the drive motor 110, and the polishing wheel 101 to move up and down together. This vertical lifting mechanism is designed to precisely adjust the height position of the polishing wheel 101 so that it can adapt to the different heights of the scope accessory workpieces, thereby ensuring the integrity of the workpiece. Each surface area to be polished can effectively contact the rotating polishing wheel 101 and achieve the desired polishing effect; the first slide 114 is connected to the fixed plate 118 and the support platform 119 via the support column 117. The bottom of the support platform 119 is equipped with a storage box 120 and a support leg 121. The storage box 120 is used to store polishing debris or tools, while the support leg 121 provides ground support to ensure the overall balance and anti-interference ability of the device; a second slide 122 is also installed at the top of the support platform 119, and a second sliding clamp 124 is slidably connected to the second slide rails 123 on both sides of the second slide 122. The second sliding clamp 124 is fixed on both sides of the second internal thread block 125, and a C-shaped plate 127 is installed at the top of the second internal thread block 125 via the support block 126; the C-shaped plate 127 is installed inside the C-shaped plate 127. A rotating motor 128 drives a rotating disk 129 to rotate. The top of the rotating disk 129 has several symmetrical fixing holes 130 for installing special fixtures that are adapted to the workpieces. The fixtures are used to hold the workpieces of the aiming scope accessories, so as to realize the active rotational polishing of the workpieces. The second internal thread block 125 is threaded to install the second thread rod 131. When the second motor 132 drives the second thread rod 131 to rotate, the second internal thread block 125 moves along the second slide rail 123, which drives the support block 126 and its C-shaped plate 127 and the rotating disk 129 to make a horizontal movement perpendicular to the first slide table 114. That is, it adjusts the relative distance between the rotating disk 129 and the workpiece it holds and the polishing wheel 101, so that the workpiece can accurately approach or move away from the polishing wheel 101.With the vertical height adjustment of the first motor 116, this horizontal movement achieves precise positioning of the workpiece and the polishing wheel 101 on the horizontal plane, thereby ensuring uniform polishing contact covering the surface of the parts, reducing local over-grinding or omissions, and improving polishing accuracy and efficiency. During the overall collaborative operation, the drive motor 110 provides the core rotational power for the polishing wheel 101, the rotation motor 128 drives the workpiece to rotate on the rotating disk 129, and the first motor 116 and the second motor 132 respectively precisely control the height position of the polishing wheel 101 and the horizontal position of the workpiece relative to the polishing wheel 101. Through the coordinated operation of these three sets of movements, the device intelligently maintains the optimal positional relationship and contact posture between the workpiece and the high-speed rotating polishing wheel 101 throughout the entire processing cycle. The modular design of the device facilitates easy component replacement and maintenance: the detachable structure of the clamping plate 105 allows for quick replacement of the polishing wheel 101, adapting to different polishing needs; all movements are controlled in a closed loop via motors and precision threaded mechanisms, avoiding errors and inefficiencies associated with manual adjustments; the combination of the storage box 120 and the support legs 121 effectively enhances environmental friendliness and operational stability, reducing dust pollution and vibration interference in the production environment, ultimately achieving high-quality, automated, and uniform polishing of scope accessories.
