Description

TECHNICAL FIELD

[0001] The utility model mainly relates to the square block magnetic material end face grinding field. BACKGROUND

[0002] The square block end face grinder is mainly used for grinding the end face of the square block magnetic material, which is mainly composed of a grinding wheel device and a rubber wheel feeding device. The two rubber wheels of the rubber wheel feeding device are driven to rotate in opposite directions by a motor. During operation, the square block magnetic material passes between the two rubber wheels, and the friction force of the rubber wheels sends the square block magnetic material into the grinding wheel device for grinding.

[0003] The existing rubber wheel feeding device is generally composed of a motor, a transmission mechanism, a linear sliding mechanism, and two rubber wheels. The linear sliding mechanism has two sliding seats, and the two rubber wheels are installed on the corresponding sliding seats through rubber wheel shafts. The distance between the two rubber wheels is adjusted by the relative movement of the two sliding seats to adapt to square block magnetic materials of different sizes. Since the rubber wheels are installed on the sliding seats of the linear sliding mechanism, a linkage structure is designed between the transmission mechanism and the linear sliding mechanism to transmit power from the motor to the rubber wheels. Therefore, when the two sliding seats of the linear sliding mechanism move relative to each other to adjust the distance, the transmission members inside the transmission mechanism will also synchronously adjust accordingly to maintain the transmission connection. This results in a complex overall structure and a large occupied space. Moreover, due to the influence of the linkage structure, the adjustment range is generally small, making it difficult to adapt to the rubber wheel distance adjustment requirements of a larger range, and the rubber wheel distance adjustment is constrained. At the same time, the frequent adjustment between the transmission members inside the transmission mechanism and the stress changes caused by the relative positions of the transmission members after adjustment will lead to unstable transmission. SUMMARY

[0004] The technical problem to be solved by the utility model is to provide a novel rubber wheel feeding device for a square block end face grinder with a simple and compact structure, a small occupied space, a large adjustment range, a high degree of freedom, and stable reliability, in view of the deficiencies of the prior art.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A novel rubber wheel feeding device for a square block end face grinder, comprising two symmetrical rubber wheel feeding assemblies, each rubber wheel feeding assembly comprising a linear module, a motor, a reversing transmission mechanism, and a rubber wheel. The two linear modules are symmetrically installed on the same horizontal line along their moving direction. The reversing transmission mechanism is installed on the sliding seat of the linear module. The motor drives the rubber wheel to rotate through the reversing transmission mechanism. The drive shaft of the motor is parallel to the moving direction of the linear module and connected to the reversing transmission mechanism. The wheel shaft of the rubber wheel is vertically installed and connected to the reversing transmission mechanism.

[0007] Further, the reversing transmission mechanism is a bevel gear meshing reversing transmission mechanism.

[0008] Further, the reversing transmission mechanism comprises a bearing seat and horizontal and vertical bevel gears meshing with each other in the bearing seat, a driving shaft of the motor is horizontally installed in the bearing seat through a bearing and fixedly connected with the horizontal bevel gear, and an axle of the rubber wheel is vertically installed in the bearing seat through a bearing and fixedly connected with the vertical bevel gear.

[0009] Further, a compression spring is sleeved on the axle of the rubber wheel to apply an elastic pushing force of the vertical bevel gear to the horizontal bevel gear, so that the vertical bevel gear is tightly matched with the horizontal bevel gear.

[0010] Further, the motor is fixedly installed on the reversing transmission mechanism.

[0011] Further, the linear module is a hand-operated linear module.

[0012] Compared with the prior art, the rubber wheel feeding device of the utility model is composed of two sets of symmetrically arranged rubber wheel feeding assemblies, each set of rubber wheel feeding assembly comprises an independent linear module, a motor, a reversing transmission mechanism and a rubber wheel, that is, each rubber wheel is independently driven to rotate by a corresponding motor and the position is independently adjusted by a corresponding linear module to realize the distance adjustment between the two rubber wheels. Moreover, the motor directly transmits power to the rubber wheel through the reversing transmission mechanism, the power transmission does not pass through the linear module, the decoupling of the linear module and the reversing transmission mechanism is realized, and the linear module and the reversing transmission mechanism are independent in structure and function. When the distance between the two rubber wheels is adjusted, only the linear module is needed to participate, and a linkage structure between the linear module and the reversing transmission mechanism is no longer needed, compared with the prior art, the structure is simpler, the adjustment range is larger, the degree of freedom is higher, and the device is more stable and reliable. Meanwhile, since the linear module and the reversing transmission mechanism are independent and self-contained, the linear module and the reversing transmission mechanism can be designed to be small and compact, and the occupied space is smaller.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the protection scope of the present invention is not limited to the following embodiments. Any improvements and modifications made to the present invention without departing from the principle of the present invention shall be considered within the protection scope of the present invention.

[0017] like Figure 1 , Figure 2 As shown, this utility model discloses a novel rubber wheel feeding device for grinding the end face of a block. It includes two symmetrically arranged rubber wheel feeding assemblies. Each assembly comprises a linear module 1, a motor 2, a reversing transmission mechanism 4, and rubber wheels 5. The two linear modules 1 are symmetrically mounted on the same horizontal line along their own direction of movement. The reversing transmission mechanism 4 is mounted on a slide of the linear module 1, and the linear module 1 drives the reversing transmission mechanism 4 to move linearly. The motor 2 drives the rubber wheels 5 to rotate via the reversing transmission mechanism 4. Specifically, the motor 2 is fixedly mounted on one side of the reversing transmission mechanism 4, and its drive shaft is parallel to the direction of movement of the linear module 1 and connected to the reversing transmission mechanism 4. The axle 6 of the rubber wheels 5 is vertically mounted and connected to the reversing transmission mechanism 4. The reversing transmission mechanism 4 converts the driving force of the motor 2 from the horizontal direction to the vertical direction, outputting it to the rubber wheels 5. When it is necessary to adjust the distance between the two rubber wheels 5, the two linear modules 1 can be moved relative to each other simultaneously. In this invention, motor 2 is preferably a servo motor, which can realize the synchronous and same speed operation of two motors 2. The servo motor is connected to the reversing transmission mechanism 4 through the reducer 3.

[0018] In this invention, the motor 2 directly transmits power to the rubber wheels 5 via the reversing transmission mechanism 4, bypassing the linear module 1. This decouples the linear module 1 from the reversing transmission mechanism 4, making them structurally and functionally independent. Therefore, when adjusting the distance between the two rubber wheels 5, only the linear module 1 needs to be involved, eliminating the need for a linkage structure between them. Compared to existing technologies, this design is simpler, offers a wider adjustment range, greater freedom, and greater stability and reliability. Furthermore, since the linear module 1 and the reversing transmission mechanism 4 are independent and self-contained, both can be designed to be small and compact, occupying less space.

[0019] Preferably, the reversing transmission mechanism 4 is a bevel gear reversing transmission mechanism. Specifically, the reversing transmission mechanism 4 includes a bearing housing 41 and mutually perpendicular meshing horizontal bevel gears 43 and vertical bevel gears 44 located within the bearing housing 41. The drive shaft of the motor 2 is horizontally mounted in the bearing housing 41 via bearing 42 and fixedly connected to the horizontal bevel gears 43. The axle 6 of the rubber wheel 5 is vertically mounted in the bearing housing 41 via bearing 42 and fixedly connected to the vertical bevel gears 44.

[0020] Preferably, a compression spring 45 is sleeved on the axle 6 of the rubber wheel 5, and is located between the vertical bevel gear 44 and the bearing 42, so as to apply an elastic thrust to the vertical bevel gear 44 to press the vertical bevel gear 44 against the horizontal bevel gear 43, and keep the transmission stable.

[0021] In other embodiments, the reversing transmission mechanism 4 can also be a worm gear mechanism or other forms of reversing mechanism, as long as it can realize the conversion of power from horizontal direction to vertical direction.

[0022] Preferably, the linear module 1 is a manual linear module. Of course, in other embodiments, the linear module 1 can also be an electric linear module. The linear module 1 is a mature prior art, and its specific structure will not be described here.
