Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of chain saws, and relates to a chain saw guide plate assembly device, in particular to an automatic riveting machine for fixing a chain saw guide plate guide wheel. BACKGROUND

[0002] The guide wheel of the chain saw guide plate is a bearing structure installed in the guide plate, which mainly functions to guide the chain to change direction smoothly and reduce friction and wear of the saw chain during turning. In the prior art, the guide wheel is usually fixed in a flat pressing manner, which can increase the size of the guide plate gear groove and affect the flatness of the guide plate.

[0003] Since the guide wheel bears the turning function during the use of the chain saw, this part is prone to failure. If the guide wheel is stuck due to failure, it will further cause irreversible damage to the chain and the guide plate. Therefore, a mechanism for more reliable installation of the chain saw guide plate guide wheel is needed. SUMMARY

[0004] The purpose of the present application is to provide an automatic riveting machine for fixing the chain saw guide plate guide wheel with better fixing effect.

[0005] To achieve the above purpose, the following technical scheme is adopted: the automatic riveting machine for fixing the chain saw guide plate guide wheel comprises a rack, and a riveting unit is arranged on the rack, characterized in that a positioning plate for placing the chain saw guide plate is arranged below the riveting head of the riveting unit, a horizontal positioning assembly for positioning the chain saw guide plate is arranged on the positioning plate, and the positioning plate is connected to the rack through an XY translation mechanism.

[0006] By using the riveting head of the riveting unit to fix and install the chain saw guide plate guide wheel on the positioning plate, a higher fixing effect can be achieved, and by controlling the docking of the guide wheel riveting head through the XY translation mechanism, accurate positioning can be achieved faster than manual adjustment, realizing high-precision automatic fixing and installation of the chain saw guide plate guide wheel.

[0007] In the automatic riveting machine for fixing the chain saw guide plate guide wheel, the horizontal positioning assembly comprises at least one first positioning column arranged on the positioning plate. Using the positioning column as a physical reference point has the advantages of simplifying the placement process of the workpiece and reducing the operation time, and using the positioning column for positioning can directly utilize the hole structure on the guide plate without additional processing of the workpiece.

[0008] In the automatic riveting machine for fixing the chain saw guide plate guide wheel, a secondary positioning structure is further arranged on one side of the positioning plate. The secondary positioning structure can further correct the posture and position of the workpiece, enhance the positioning stability, avoid displacement caused by external force during processing, and ensure the riveting quality.

[0009] In the automatic riveting machine for fixing the guide wheel of the chain saw guide plate, the secondary positioning structure comprises a support plate arranged on one side of the positioning plate, and a secondary positioning member is arranged on the support plate, and the support surface of the secondary positioning member is located on the same plane as the top surface of the positioning plate.

[0011] In the automatic riveting machine for fixing the guide wheel of the chain saw guide plate, the adjusting structure comprises a strip-shaped groove arranged on the support plate, and the positioning body is arranged in the strip-shaped groove, and a positioning module is arranged between the positioning body and the strip-shaped groove for positioning after adjustment. The strip-shaped groove can provide more accurate adjustment freedom, allowing the positioning body to move continuously in the horizontal direction, and can accurately match the tolerances of chain saw guide plates of different sizes, ensuring the accuracy of positioning.

[0012] In the automatic riveting machine for fixing the guide wheel of the chain saw guide plate, the positioning body comprises a disc body and a protrusion arranged on the disc body. Alternatively, the cross section of the positioning body is U-shaped and can surround the rear end of the chain saw guide plate. Alternatively, the cross section of the positioning body is U-shaped and can surround the rear end of the chain saw guide plate, and a step is arranged in the U-shaped seat. The positioning body adopts three optional structures disc body + protrusion, U-shaped surrounding, and U-shaped with step, and each structure can provide targeted advantages for different working conditions.

[0013] In the automatic riveting machine for fixing the guide wheel of the chain saw guide plate, the support plate is located below the positioning plate, and a gap is formed between the support plate, the positioning body and the positioning plate for easy taking and placing. The existence of the gap provides operation space, so that the chain saw guide plate can be safely and conveniently placed on the positioning plate or taken off from the positioning plate, thereby avoiding increasing the difficulty and time of taking and placing, and causing the operator to be injured or the workpiece to be bumped.

[0014] In the automatic riveting machine for fixing the guide wheel of the chain saw guide plate, the support plate and the positioning plate are detachably connected. Alternatively, the support plate is integrated with the positioning plate. Quick replacement / maintenance: the support plate and the positioning plate are detachably connected, so that when the support plate or the secondary positioning structure thereon is damaged due to wear, impact or the need for design adjustment, the entire positioning plate assembly does not need to be replaced. Only the connecting piece needs to be disassembled, and the support plate part can be repaired or replaced alone, significantly reducing maintenance cost and downtime. The design of the support plate integrated with the positioning plate has higher overall structural rigidity and stability, and is less likely to displace or deform when subjected to pressure and vibration during spin riveting, which helps to ensure higher processing accuracy.

[0015] In the automatic spin riveting machine for fixing the guide wheel of the chain saw guide plate described above, the positioning plate is connected with the connecting plate, at least two plug-in holes are provided on the connecting plate, the XY translation mechanism is connected with the plug-in holes through the connecting plug, the XY translation mechanism and the connecting plug are located below the operation platform, and the connecting plate is located on the top surface of the operation platform. The operation platform is provided with a movable hole capable of connecting the connecting plug with an external plug-in hole.

[0016] In the automatic spin riveting machine for fixing the guide wheel of the chain saw guide plate described above, the XY translation mechanism comprises X-axis moving units and Y-axis moving units distributed vertically. The X-axis moving units comprise a horizontal sliding block sliding rail assembly and a horizontal screw nut unit, and the Y-axis moving units are arranged on the horizontal sliding block sliding rail assembly. The Y-axis moving units comprise a vertical sliding block sliding rail assembly and a vertical screw nut unit, and the vertical sliding block sliding rail assembly is provided with a vertical sliding plate connected with the positioning plate. The Y-axis moving units are arranged on the horizontal sliding plate of the X-axis moving units. This structure can effectively resist the downward pressure and vibration generated during spin riveting, reduce deformation and vibration transmission, and ensure the stability of the positioning plate and the workpiece after accurate positioning. Moreover, the X-axis and the Y-axis each have an independent guide rail system and a sliding plate. This design provides high-precision linear guidance, ensures that the movements of the two axes do not interfere with each other, and reduces displacement errors.

[0017] Compared with the prior art, the automatic spin riveting machine for fixing the guide wheel of the chain saw guide plate has the following advantages: 1. The spin riveting fixing method is adopted, so that the guide plate guide wheel has good fixing effect. 2. Spin riveting avoids the increase of the width of the guide plate gear groove, and the processing quality is good. 3. It avoids affecting the flatness of the guide plate, and has strong stability. 4. It has an adjusting mechanism, and has strong adaptability to different workpieces. BRIEF DESCRIPTION OF DRAWINGS
