Description

Technical Field

[0001] The invention relates to the technical field of saw chain guide plates, and in particular to a double-sided polishing device and process for a saw chain guide plate. Background Art

[0002] The existing saw chain guide plates need to be polished on their outer surfaces during the production and processing. During the polishing process, the existing equipment has uneven pressure distribution, resulting in differences in the polishing effects on both sides of the guide plates, affecting the overall quality of the product. Moreover, traditional polishing equipment usually performs single-sided polishing, and the guide plates need to be turned over for processing, which increases the operation time and reduces production efficiency. Based on this, a double-sided polishing device and process for saw chain guide plates are designed. Summary of the invention

[0003] In order to overcome at least one of the defects of the prior art, the present invention provides a double-sided polishing device and process for a saw chain guide plate. The double-sided polishing device and the lifting mechanism cooperate to ensure that both sides of the saw chain guide plate are polished at the same time, and the pressure sensor can ensure that the polishing effect of both sides is consistent.

[0004] The technical solution adopted by the present invention to solve the problem is:

[0005] A double-sided polishing device for a saw chain guide comprises: a polishing box, wherein the two ends of the polishing box respectively have a feed port and a discharge port for conveying the saw chain guide, and the interior of the polishing box is hollow to form a accommodating chamber, and a slot is opened on one opposite side of the polishing box; a fixing clamp, wherein a portion of the fixing clamp is arranged in the accommodating chamber and a portion passes through the slot and extends to the outside of the polishing box, and the fixing clamp is used to clamp the saw chain guide; a slide rail structure, wherein the slide rail structure is arranged in the accommodating chamber, and the slide rail structure is used to drive the fixing clamp to move from the feed port to the discharge port; a double-sided polishing device, wherein the double-sided polishing device is arranged in the accommodating chamber and is used to polish the upper and lower surfaces of the saw chain guide; and a lifting structure, wherein the lifting structure is arranged in the accommodating chamber and is used to drive the double-sided polishing device to move longitudinally.

[0006] By adopting the above scheme, the upper and lower surfaces of the saw chain guide are polished simultaneously by a double-sided polishing device, ensuring that the pressure and polishing effect on both sides of the guide are uniform, thereby effectively solving the problem of polishing effect difference caused by uneven pressure distribution in traditional single-sided polishing, and significantly improving the overall quality of the product; and realizing double-sided polishing at the same time, eliminating the step of turning over in the traditional process, shortening the processing time, and further improving production efficiency.

[0007] Furthermore, the slide rail structure includes: a working box, which is open at the top and hollow inside, and is assembled on two opposite side walls of the polishing box; a screw rod, which is arranged inside the working box and is arranged along the extension direction of the working box; a first drive motor, which is assembled on the outer surface of the polishing box, and the output shaft of the first drive motor is transmission-connected to the screw rod.

[0008] By adopting the above solution, the fixed fixture can move along the path of the slide rail structure, which helps to improve the polishing quality and consistency; through the automatic control of the first drive motor, the slide rail structure can automatically drive the fixed fixture to move from the feed port to the discharge port without manual intervention. This not only reduces the operation time, but also reduces the impact of human factors on the polishing process, and improves production efficiency.

[0009] Furthermore, the fixing fixture includes: a screw slider, the two screw sliders are respectively spirally connected to the two screws; a first fixture, the first fixture is assembled on the top of one of the screw sliders; a clamping part, the clamping part is assembled on the top of the other screw slider, and a spiral hole is opened on the clamping part; a hand-holding part, the hand-holding part passes through the spiral hole and is spirally connected to the spiral hole; a second fixture, the second fixture is fixedly connected to one end of the hand-holding part; wherein a gap is left between the first fixture and the second fixture.

[0010] By adopting the above solution, a gap is left between the first clamp and the second clamp, and this design enables the clamp to adapt to saw chain guides of different thicknesses and sizes. By adjusting the position of the hand-held part in the spiral hole, the distance between the two clamps can be easily adjusted to ensure the stability and flexibility of clamping; and each part in the fixed clamp is relatively independent, which is convenient for disassembly and replacement; through the spiral connection of the screw slider and the spiral adjustment of the hand-held part, the operator can quickly and accurately clamp the saw chain guide, reducing the clamping time and improving production efficiency.

[0011] Furthermore, the hand-held part includes: a connecting rod, one end of which is fixedly connected to the second clamp; a spiral part, which is spirally connected to the spiral hole, and one end of the spiral part is fixedly connected to the other end of the connecting rod; a hand-held rod, which is fixedly connected to the other end of the spiral part; wherein the hand-held rod passes through the slot and is exposed outside the polishing box.

[0012] By adopting the above solution, the design of the hand-held lever enables the operator to conveniently place the saw chain guide between the first clamp and the second clamp, and adjust the gap between the two clamps by rotating the spiral portion on the hand-held lever, thereby achieving a stable clamping of the saw chain guide. This design reduces the complexity of operation and improves work efficiency.

[0013] Furthermore, the first clamp and the second clamp are both provided with a buffer block.

[0014] By adopting the above scheme, due to the effect of the buffer block, the saw chain guide can maintain a more stable posture during the polishing process, which helps to achieve uniform polishing on both sides and reduce uneven polishing caused by unstable clamping; the buffer block serves as an intermediary between the clamp and the saw chain guide, which can reduce direct contact and friction between the two, thereby reducing the wear rate of the clamp and the saw chain guide and extending the service life of the equipment.

[0015] Furthermore, the double-sided polishing device includes: a second driving motor; a polishing wheel, which is drivingly connected to the output shaft of the second driving motor; wherein the polishing wheel is relatively arranged above and below the first clamp and the second clamp.

[0016] By adopting the above solution, the polishing wheels are relatively arranged above and below the first clamp and the second clamp, so that the saw chain guide plate can be simultaneously acted upon by the upper and lower polishing wheels when passing through, thereby achieving double-sided polishing at the same time. This design significantly improves polishing efficiency and reduces processing time.

[0017] Furthermore, the lifting structure is a hydraulic device, which is mounted on the top and bottom of the polishing box and is respectively connected to the two second drive motors.

[0018] By adopting the above solution, the effect of driving the second drive motor to move longitudinally is achieved through the hydraulic device.

[0019] Furthermore, a pressure sensor for detecting pressure in real time is arranged between the second driving motor and the polishing wheel.

[0020] By adopting the above solution, the pressure sensor can monitor the pressure applied by the polishing wheel on the saw chain guide in real time during the polishing process. This real-time monitoring function helps to ensure that the polishing pressure is always kept within the optimal range, avoiding polishing quality problems caused by excessive or insufficient pressure.

[0021] A saw chain guide plate double-sided polishing process, using any of the saw chain guide plate double-sided polishing devices described above, is characterized by comprising the following steps:

[0022] S1, inserting the saw chain guide plate from the feed inlet and placing it between the first clamp and the second clamp;

[0023] S2, rotating the hand-held part to clamp the saw chain guide plate through the first clamp and the second clamp;

[0024] S3, starting the first drive motor and the second drive motor to drive the fixing fixture to move between the two polishing wheels;

[0025] S4, the pressure sensor detects the pressure and transmits the signal to the controller, and the controller controls the hydraulic device to move down or up to contact the saw chain guide to achieve polishing;

[0026] S5. After polishing is completed, the saw chain guide is transported to the discharge port. BRIEF DESCRIPTION OF THE DRAWINGS
