Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically a grinding machine for processing motorcycle parts. Background Technology

[0002] Motorcycles are two- or three-wheeled vehicles powered by gasoline engines and steered by handlebars. They are lightweight, agile, and fast, widely used for patrolling, passenger and freight transport, and also as sports equipment. Broadly speaking, motorcycles are categorized into street bikes, road racing motorcycles, off-road motorcycles, cruisers, and touring motorcycles. The machining of motorcycle parts generally requires the use of grinding machines.

[0003] To prevent coolant and grinding dust from splashing during machining and to protect operators, existing grinding machines used for motorcycle parts processing are equipped with protective covers. However, the closing torque and impact of these covers are often too high, posing a significant risk of mechanical crushing. The shear points formed between the moving parts and the static frame can easily cause pinching injuries if the operator's limbs are not removed in time, constituting a safety hazard. Utility Model Content

[0004] The purpose of this utility model is to provide a grinding machine for processing motorcycle parts, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding machine for processing motorcycle parts, comprising a grinding machine body, a protective cover mounted on the grinding machine body, a protective door that can be horizontally pushed and pulled on the protective cover, a door frame post on the side of the protective door, the protective door and the door frame post achieving a sealed closure through planar contact, the door frame post and the protective cover being an integral structure, a push rod placed horizontally on the side of the protective door near the door frame post, a spring seat that can rotate upwards mounted on the door frame post, a spring rod mounted on the side of the spring seat facing the protective door, gears connected to both ends of the spring seat through a rotating shaft, a rack meshing with the gears above the gears, the rack and the push rod being placed horizontally along the same straight line.

[0006] Preferably, the door frame post is provided with a horizontally through hole, and a horizontally movable rack passes through the through hole.

[0007] Preferably, a groove is provided on the side of the door frame post near the protective door, and mounting slots are provided at both ends of the groove. The groove and the mounting slots are connected by mounting holes. A spring seat is placed in the groove, and the rotating shafts at both ends of the spring seat pass through the mounting holes and extend into the mounting slots, and are coaxially and fixedly connected with the gears provided in the mounting slots.

[0008] Preferably, there are two elastic rods.

[0009] Preferably, the side of the spring seat facing the protective door has a movable cavity, and a spring rod that can be horizontally extended and retracted is installed in the movable cavity.

[0010] Preferably, the elastic rod includes a slider movably connected to the movable cavity. The slider is connected in sequence with a rod body and a contact head in the horizontal direction facing the protective door. A spring is sleeved on the part of the rod body that extends out of the movable cavity.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 As shown, a grinding machine for processing motorcycle parts includes a grinding machine body 1 for processing motorcycle parts. A protective cover 2 is installed on the grinding machine body 1 to enclose and protect the worktable. The protective cover 2 is provided with a protective door 3 that can be horizontally pushed and pulled to open and close the protective cover 2. A door frame post 4 is provided on the side of the protective door 3. The protective door 3 and the door frame post 4 achieve a sealed closure through planar contact. The door frame post 4 and the protective cover 2 are an integral structure. A horizontally placed push rod 19 is provided on the side of the protective door 3 near the door frame post 4 to push the rack 9 to move. A door frame post 4 is mounted with... There is an upward-rotating spring seat 5. The spring seat 5 can rotate upward when the protective door 3 is closed. A spring rod 6 is installed on the side of the spring seat 5 facing the protective door 3. It contacts the closed protective door 3, so that the protective door 3 is buffered for a short distance before the push rod 19 contacts the rack 9. The two ends of the spring seat 5 are connected to gears 8 through the rotating shaft 7. The rotation of the gear 8 drives the spring seat 5 to rotate. A rack 9 is provided above the gear 8 and meshes with it. The movement of the rack 9 drives the rotation of the gear 8. The rack 9 and the push rod 19 are placed horizontally along the same straight line so that the push rod 19 can push the rack 9 to move.

[0023] The door frame post 4 is provided with a horizontally drilled through hole 10, through which a horizontally movable rack 9 is passed to limit the rack 9 and ensure that the rack 9 can move horizontally.

[0024] A groove 11 is provided on the side of the door frame post 4 near the protective door 3. Mounting slots 13 are provided at both ends of the groove 11, and the groove 11 and the mounting slots 13 are connected by mounting holes 12. A spring seat 5 is placed in the groove 11. The rotating shafts 7 at both ends of the spring seat 5 pass through the mounting holes 12 and extend into the mounting slots 13, and are coaxially fixedly connected with the gears 8 set in the mounting slots 13, so that the spring seat 5 can be fixed in the axial position on the door frame post 4.

[0025] There are two spring bars 6, which provide better cushioning force.

[0026] A movable cavity 14 is provided on the side of the spring seat 5 facing the protective door 3. A spring rod 6 that can be horizontally extended and retracted is installed in the movable cavity 14. The spring rod 6 includes a slider 15 that is movably connected to the movable cavity 14. A rod body 16 and a contact head 17 are connected to the slider 15 in sequence in the horizontal direction facing the protective door 3. A spring 18 is sleeved on the part of the rod body 16 that extends out of the movable cavity 14. The two ends of the spring 18 abut against the outer wall of the spring seat 5 and the outer wall of the contact head 17, respectively, so that the spring rod 6 can perform horizontal elastic movement without disengaging from the movable cavity 14.

[0027] The contact head 17 is hemispherical, with the spherical side facing the protective door 3. The contact head 17 is made of sponge, which makes a flexible collision with the protective door 3 to prevent damage to the protective door 3.

[0028] The spring seat 5 is a cuboid and the side away from the protective door 3 is arc-shaped, allowing the spring seat 5 to continue rotating upwards.

[0029] Working principle:

[0030] When the operator pushes the protective door 3 horizontally to close, the door first contacts the sponge contact head 17 of the spring rod 6 mounted on the spring seat 5. As the protective door continues to move, it pushes the rod body 16 of the spring rod 6 back into the movable cavity 14. At this time, the spring 18 sleeved on the rod body 16 is compressed, generating a reverse buffering force. This force effectively absorbs the closing kinetic energy of the protective door, reducing its speed and achieving a gentle initial closure and buffering. Due to the presence of the spring rod 6, the protective door will first perform a short buffering movement. After this, the push rod 19 mounted on the side of the protective door will then contact the end face of the rack 9. After the buffering phase, the pushing force for the protective door to continue closing will be directly transmitted to the rack 9 through the push rod 19, pushing the rack 9 to move horizontally in the through hole 10 of the door frame post 4. The horizontally moving rack 9 drives the gear 8 meshing with it to rotate. The gear 8 drives the spring seat 5 to rotate upwards and lift through the rotating shaft 7. This action causes the spring seat 5 and spring rod 6, which were originally located on the closing path of the protective door, to shift as a whole, making room for the final closing of the protective door. As the spring seat 5 rotates upward to make room, the protective door 3 can continue to move without obstruction, and finally its side achieves complete planar contact and sealing with the door frame post 4.
