Description

Technical Field

[0001] This utility model relates to the technical field of safety protection devices for cutting machines, and in particular to a novel rapid rotation mechanism for the protective cover of a cutting machine. Background Technology

[0002] As a commonly used piece of equipment in the machining field, cutting machines have high-speed rotating parts (such as saw blades and gears) that pose significant safety risks. Therefore, protective covers are needed to shield these rotating parts to prevent operators from accidentally touching them and causing personal injury. In actual use, to meet different processing needs or for equipment maintenance, it is often necessary to rotate and adjust the protective covers to expose or shield specific areas.

[0003] Currently, the protective cover of existing cutting machines is typically tightened or loosened using screws or quick-release wrenches when rotation is required. This method is cumbersome, inefficient, and poses safety hazards during adjustment. For example, existing technologies use an aluminum gearbox with an iron protective cover, secured by a spring-loaded pressure plate with bubble points and three screws. This structure is complex, inconvenient to adjust, and not conducive to rapid response to safety requirements. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to solve the problem that the rotation of the protective cover of the cutting machine requires the use of tools and is inconvenient to operate in the prior art, this utility model provides a new type of rapid rotation mechanism for the protective cover of the cutting machine.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a novel rapid rotation mechanism for a cutting machine's protective cover, comprising a gearbox, a gearbox cover, a first screw, an iron protective cover, an elastic pressure plate, and a second screw; the gearbox cover is fixed to the gearbox, the iron protective cover is sleeved on the outside of the gearbox cover, and the inner wall of the iron protective cover is clearance-fitted with the outer wall of the iron protective cover; the elastic pressure plate is disposed above the iron protective cover and connected to the gearbox cover; the iron protective cover is provided with multiple positioning holes, and the elastic pressure plate is provided with circular bubble dots that mate with the positioning holes; the gearbox is provided with an annular step higher than the iron protective cover.

[0006] Furthermore, there are four first screws, which are evenly distributed around the circumference of the gearbox cover and pass through the side wall of the gearbox cover and the gearbox in sequence, thus fixing the gearbox cover to the gearbox.

[0007] Furthermore, there are three second screws, which are evenly distributed around the circumference of the elastic pressure plate and pass through the top of the elastic pressure plate and the gearbox cover in sequence, thus fixing the elastic pressure plate and the gearbox cover together.

[0008] Furthermore, the top of the gearbox is provided with an annular step, the bottom of the gearbox cover abuts against the top end face of the annular step, and the height of the annular step is higher than the distance from the bottom end face of the iron cover to the top of the gearbox.

[0009] Furthermore, the lower surface of the elastic pressure plate is provided with two circular bubbles, which are symmetrically distributed along the axis of the elastic pressure plate.

[0010] Furthermore, the top end face of the iron shield is provided with 6 positioning holes, which are evenly distributed along the circumference of the iron shield, and the position of the positioning holes corresponds to the movement trajectory of the circular bubble on the elastic pressure plate.

[0011] The beneficial effects of this utility model are: The novel rapid rotation mechanism of the cutting machine's protective cover described in this utility model enables rapid rotation of the cover without the use of any tools, simplifying operation and improving work efficiency. The combination of circular bubble dots and positioning holes ensures both a secure lock-up of the cover in a non-rotating state and flexible adjustment during rotation. This effectively reduces the risk of personal injury due to improper operation or untimely adjustment, enhancing the safety performance of the equipment. Attached Figure Description

[0017] like Figure 1-2 As shown, a novel rapid rotation mechanism for a cutting machine's protective cover includes a gearbox 1, a gearbox cover 2, a first screw 3, an iron protective cover 4, an elastic pressure plate 5, and a second screw 6. The gearbox cover 2 is fixed to the gearbox 1, and the iron protective cover 4 is fitted onto the outside of the gearbox cover 2, with the inner wall of the iron protective cover 4 and the outer wall of the iron protective cover 4 having a clearance fit. The elastic pressure plate 5 is located above the iron protective cover 4 and connected to the gearbox cover 2. The iron protective cover 4 has multiple positioning holes 7, and the elastic pressure plate 5 has circular bubble points 8 that mate with the positioning holes 7. The gearbox 1 has an annular step 9 that is higher than the iron protective cover 4.

[0018] Four first screws 3 are provided, evenly distributed along the circumference of the gearbox cover 2, and sequentially penetrate the sidewalls of the gearbox cover 2 and the gearbox 1, thus fixing the gearbox cover 2 to the gearbox 1. Three second screws 6 are provided, evenly distributed along the circumference of the elastic pressure plate 5, and sequentially penetrate the top of the elastic pressure plate 5 and the gearbox cover 2, thus fixing the elastic pressure plate 5 to the gearbox cover 2.

[0019] The gearbox 1 has an annular step 9 on its top. The bottom of the gearbox cover 2 abuts against the top surface of the annular step 9, and the height of the annular step 9 is greater than the distance from the bottom surface of the iron cover 4 to the top of the gearbox 1. The lower surface of the elastic pressure plate 5 has two circular bubbles 8, which are symmetrically distributed along the axis of the elastic pressure plate 5. The top surface of the iron cover 4 has six positioning holes 7, which are evenly distributed circumferentially along the iron cover 4, and the positions of the positioning holes 7 correspond to the movement trajectories of the circular bubbles 8 on the elastic pressure plate 5.

[0020] During assembly, the gearbox cover 2 is placed on the annular step 9 on the top of the gearbox 1, so that the bottom of the gearbox cover 2 abuts against the top end face of the annular step 9; four first screws 3 are evenly distributed around the circumference of the gearbox cover 2, and the first screws 3 are sequentially passed through the side walls of the gearbox cover 2 and the gearbox 1, and tightened by threaded connection to fix the gearbox cover 2 to the gearbox 1; the iron cover 4 is fitted on the outside of the gearbox cover 2, ensuring that the inner wall of the iron cover 4 is in clearance fit with the outer wall of the gearbox cover 2, and the bottom end face of the iron cover 4 is located below the annular step 9 of the gearbox 1; the elastic pressure plate 5 is covered on the top end face of the iron cover 4, so that the two circular bubbles 8 on the lower surface of the elastic pressure plate 5 abut against the positioning holes 7 on the top of the iron cover 4; three second screws 6 are evenly distributed around the circumference of the elastic pressure plate 5, and the second screws 6 are sequentially passed through the elastic pressure plate 5 and the top of the gearbox cover 2, and tightened by threaded connection to fix the elastic pressure plate 5 to the gearbox cover 2, and the assembly is completed.

[0021] In use, when it is necessary to rotate the iron cover 4, the operator directly applies a circumferential external force to the iron cover 4. The circular bubble point 8 of the elastic pressure plate 5 undergoes elastic deformation under pressure and slides along the top end face of the iron cover 4, causing the iron cover 4 to rotate around the axis of the gearbox cover 2. When it rotates to the target position, the external force is stopped, and the circular bubble point 8 resets under elastic action and re-abuts against the positioning hole 7 or end face on the top of the iron cover 4, thereby achieving the positioning and fixing of the iron cover 4 and preventing its accidental rotation.

[0022] In this specification, the illustrative expressions of the terms do not necessarily refer to the same embodiments. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments.
