DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, the utility model is further described below in conjunction with specific embodiments.

[0023] In the description of the present invention, it should be understood that the terms "lateral", "longitudinal", "end", "edge", "sidewall", "up", "down", "upper part", "lower part", "directly above", "surface", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", "end", "head" and "tail" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the technical solution of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation to the present invention.

[0024] The present application proposes a planar cam, which is specifically as follows:

[0025] For reference Figure 1-2 The present application mainly includes a base plate 1, a connecting member 2 detachably mounted on the base plate 1, and a balancing member 3 arranged on one side of the connecting member 2. The coordination between the structures facilitates the replacement or polishing of a separate detachable part of the structure, thereby increasing the use efficiency of the structure and the convenience of subsequent maintenance.

[0026] For reference Figure 1-2 The bottom plate 1 is used to connect with the rest of the structure, and to reinforce the connection parts 2 and the balancing parts 3.

[0027] For reference Figure 1-2 , the connecting member 2 and the balancing member 3 are both arranged on the base plate 1 and reinforced by the base plate 1; the connecting member 2 includes a bent plate 21 and a transverse plate 22, and the bent plate 21 and the transverse plate 22 are mutually clamped; the bottom of the bent plate 21 is connected with a detachable first arc shaft 23 by bolts; when a single part is used in the installation and use of the equipment, it is necessary to run-in the parts and the connected parts, and the connecting parts may be damaged during the running-in process; taking this problem into consideration, the application sets the first arc shaft 23 in a detachable form. When purchasing, the first arc shaft 23 can be taken out and polished according to the installation position and the situation of the required connecting parts, so that the initial lubrication can achieve better smoothness when the parts are working, and secondly, the detachable form will not affect the other structures during the polishing.

[0028] Secondly, considering the stability of the first arc shaft 23 in connection, the bending plate 21 is composed of a connecting shaft 211 and a clamping shaft 212. A groove 213 adapted to the first arc shaft 23 is opened at the bottom of the connecting shaft 211, and the clamping shaft 212 is fixedly installed in the groove 213; when taking out the first arc shaft 23, it is only necessary to remove the bolts or other connecting parts used to connect the first arc shaft 23 and the clamping shaft 212, and then grind or replace them.

[0029] At the same time, in order to further enhance the stability of the connection between the structures, a plurality of clamping tracks 5 are provided on the surface of the clamping shaft 212, and the clamping tracks 5 are connected and clamped with the first arc-shaped shaft 23 to enhance the connectivity between the connections.

[0030] For reference Figure 1-2 , the balancing member 3 is located on the opposite side of the connecting member 2 and is arranged on the bottom plate 1. The reason for setting the balancing member 3 and the connecting member 2 to be detachable is that in a structure, one-way friction may occur, causing wear on one side, while the damage degree of the other side is not high. If the whole is replaced, the cost is also high. Therefore, in order to solve this problem, the present application sets the connecting member 2 and the balancing member 3 to be detachable, so that in the subsequent process, one side can be disassembled and replaced;

[0031] The surface of the balancing member 3 is flush with one side of the bent plate 21, and there is a gap between the bent plate 21 and the balancing member 3 to form a slide rail 4; the slide rail 4 is the track for the connected moving part to perform reciprocating swinging motion; the two sides of the track are the inner edges of the balancing member 3 and the connecting member 2, and work along the edges of the two parts during movement.

[0032] The balancing member 3 includes a balancing plate 31 and a second arc-shaped shaft 32, and the second arc-shaped shaft 32 is detachably connected to the balancing plate 31; the edge of the balancing plate 31 constitutes one side of the linear track of the slide rail 4, and symmetrically constitutes the two sides of the linear track of the slide rail 4 with the edge of the connecting shaft 211; the second arc-shaped shaft 32 and the first arc-shaped shaft 23 constitute the two sides of the curved end of the slide rail 4; the connection structure between the second arc-shaped shaft 32 and the balancing plate 31 is consistent with the above-mentioned connection structure between the first arc-shaped shaft 23 and the connecting shaft 211, and the present application will not elaborate on it.

[0033] By setting the straight end and the bent end of the slide rail 4 to a separated state, a more suitable curvature can be polished for use according to the specific situation; in some states, it is more suitable for the use of parts with specific needs, reducing the problem of low adaptability under the condition of ordering parts; relatively speaking, the cost of using this part is lower than that of customized parts, and the problem of customized parts being incompatible and difficult to modify is reduced.

[0034] At the same time, in a structural design, when designing the appropriate arc to match the moving parts, the wear and tear caused by grinding the parts will not affect the overall structure, thereby reducing the wear and tear of parts during the design and construction.

[0035] In the utility model, the working steps of the device are as follows:

[0036] 1. First, connect the connecting piece 2 with the balancing piece 3, and make adjustments by the movement of the moving piece in the slide rail 4 formed by the connecting middle part when it is not installed;

[0037] 2. Secondly, during the adjustment process, first calculate the arc that needs to be polished and make marks on the first arc shaft 23 and the second arc shaft 32. After marking, disassemble the first arc shaft 23 and the second arc shaft 32 for polishing;

[0038] 3. Then, reinstall the polished parts and start using them. If they are worn during use, remove the single-side connector 2 or the balancing part 3 for replacement.

[0039] 4. Finally, check the wear and tear regularly and perform maintenance work.

[0040] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of protection claimed by the utility model. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
