Description

Technical Field

[0001] This invention relates to the field of chamfering devices, and in particular to a roller chamfering device. Background Technology

[0002] Rubber rollers are roller-shaped products made of metal or other materials as the core and covered with rubber through vulcanization. They are mainly used in papermaking, dyeing and printing, grain processing, metallurgy, and plastics processing.

[0003] Rubber rollers include a roller and a central spindle. In some products, the ends of the roller are required to be chamfered both inside and out. However, there is no dedicated equipment in the existing technology that can perform chamfering both inside and out at the same time. Therefore, there is an urgent need for a new type of equipment to perform the above chamfering process. Summary of the Invention

[0004] The purpose of this invention is to provide a roller chamfering device to solve the problems existing in the prior art, and to perform both internal and external chamfering, thereby improving work efficiency.

[0005] To achieve the above objectives, the present invention provides the following solution:

[0006] This invention provides a roller chamfering device, comprising: a fixing mechanism, a chamfering driving device, and a chamfering tool; the fixing mechanism is used to fix the roller, and during chamfering, the chamfering driving device can drive the chamfering tool to rotate around the axis of the roller and drive the chamfering tool to move toward the roller; the chamfering tool has an inner chamfering portion and an outer chamfering portion, the inner chamfering portion is used to chamfer the inner edge of the roller end, and the outer chamfering portion is used to chamfer the outer edge of the roller end.

[0007] Preferably, the fixing mechanism includes a lower support member, an upper clamping member, and an upper clamping member driving device. The lower support member is fixedly disposed and used to support the roller. The upper clamping member is located above the lower support member. The upper clamping member driving device is used to drive the upper clamping member to move downward until the roller is pressed against the lower support member.

[0008] Preferably, it further includes a linear motion drive device and a positioning member. The linear motion drive device is located at one end of the lower support member, and the positioning member can move to the other end of the lower support member. The end of the positioning member facing the lower support member has a conical surface forming a positioning tip. The linear motion drive device can drive the roller on the lower support member to move toward the positioning member until the positioning tip is half-inserted into the end of the roller. After the fixing mechanism fixes the roller in place, the positioning member moves away from the roller.

[0009] Preferably, the chamfering drive device can also drive the chamfering tool to move up and down. The chamfering tool and the positioning member are mounted on the same support frame. The chamfering tool is rotatably mounted on the support frame, and the positioning member is fixedly mounted on the support frame. The chamfering drive device can drive the support frame to move up and down and back and forth.

[0010] Preferably, the linear motion drive device includes a cylinder and an elastic top member. The elastic top member is fixedly disposed at the free end of the cylinder. The cylinder is used to drive the elastic top member to move to the end of the roller and squeeze the roller until the positioning tip is half-inserted into the end of the roller.

[0011] Preferably, both the lower support and the upper clamping member are V-shaped blocks.

[0012] Preferably, the fixing mechanism further includes a stop bar and a stop bar driving device. The upper clamping member is used to press the part of the roller near the rear end. The stop bar is located above the part of the roller near the front end. A lower support member is provided directly below the stop bar.

The inner chamfering section is used to chamfer the inner edge of the roller end, and the outer chamfering section is used to chamfer the outer edge of the roller end. Therefore, the inner and outer edges of the roller can be chamfered simultaneously, performing two chamfering processes in one operation, thus improving work efficiency. Attached Figure Description

Detailed Implementation

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

[0022] The purpose of this invention is to provide a roller chamfering device to solve the problems existing in the prior art, and to perform both internal and external chamfering, thereby improving work efficiency.

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] This invention provides a roller chamfering device, such as Figures 1-3 As shown, it includes: a fixing mechanism, a chamfering drive device 1, and a chamfering tool 2; the fixing mechanism is used to fix the roller, and during chamfering, the chamfering drive device 1 can drive the chamfering tool 2 to rotate around the axis of the roller and drive the chamfering tool 2 to move toward the roller; the chamfering tool 2 has an inner chamfering part and an outer chamfering part, the inner chamfering part is used to chamfer the inner edge of the roller end, and the outer chamfering part is used to chamfer the outer edge of the roller end.

[0025] The fixing mechanism is used to restrict the axial position and rotational freedom of the roller to prevent machining defects caused by changes in the workpiece position during chamfering.

[0026] To facilitate the fixing of the roller, embodiments of the present invention can use left-right clamping or top-bottom clamping to fix the roller. In order to facilitate the placement of the roller, one component of the clamping assembly is often fixedly set and a support station is provided. After the workpiece is placed on the support station, the other clamping assembly is driven to move towards the fixed assembly to achieve clamping. Specifically, in one embodiment, the fixing mechanism includes a lower support member 5, an upper pressing member 61 and an upper pressing member driving device 6. The lower support member 5 is fixedly set and used to support the roller. The upper pressing member 61 is located above the lower support member 5. The upper pressing member driving device 6 is used to drive the upper pressing member 61 to move downward until the roller is pressed against the lower support member 5.

[0027] In this embodiment, the lower support member 5 can be set as one. When one is set, a long support surface is required to form a continuous support station. Alternatively, multiple lower support members 5 can be set. When multiple are set, each lower support member 5 has a short support surface, and the support surfaces are spaced apart, thus achieving a lightweight design.

[0028] Rollers can be made of various materials. When the roller is made of an elastic material, for example, the outer layer of the roller is made of rubber and the inner layer is made of aluminum, such a roller is prone to deformation when clamped, which will lead to defects when chamfering. Therefore, in order to solve this problem, in this embodiment of the invention, the part of the roller near the rear end is clamped and fixed, and the part near the front end is anti-swing and limited, without clamping and fixing. The fixing mechanism in the solution provided in this embodiment also includes a stop bar 41 and a stop bar driving device 4. The upper clamping member 61 is used to clamp the part of the roller near the rear end. The stop bar 41 is located above the part of the roller near the front end. A lower support member 5 is provided directly below the stop bar 41. The stop bar driving device 4 can drive the stop bar 41 to move downward to near the roller and restrict the roller in the V-block of the lower support member 5.

[0029] In this embodiment, the stop bar 41 is moved down to contact the roller, or moved down to have a small gap between it and the roller, so as to prevent the roller from swinging due to friction or cutting force when chamfering.

[0030] Both the upper clamping component drive device 6 and the stop lever drive device 4 can be pneumatic cylinders, electric cylinders, or hydraulic cylinders, and both are fixedly mounted on the frame 8.

[0031] Figures 1-3 As shown, a structure with two lower support members 5 is illustrated, corresponding to the front and rear ends of the roller respectively.

[0032] To improve chamfering accuracy and mechanization, in one embodiment of the present invention, the lower support 5 is a V-shaped block, and the roller chamfering device provided in this embodiment also includes a linear motion drive device 7 and a positioning member 3. The linear motion drive device 7 is located at one end of the lower support 5, and the positioning member 3 can move to the other end of the lower support 5. The end of the positioning member 3 facing the lower support 5 is tapered to form a positioning tip 31. The linear motion drive device 7 can drive the roller on the lower support 5 to move toward the positioning member 3 until the positioning tip 31 is half inserted into the end of the roller. After the fixing mechanism fixes the roller that has moved into place, the positioning member 3 moves away from the roller.

[0033] In this embodiment, since it is difficult to place the roller accurately when placing it manually or using other automated mobile equipment, a V-block is used to ensure its axial position, and a linear motion drive device 7 and a positioning component 3 are used to position its axial position, thereby improving the processing accuracy. Moreover, the positioning process does not require manual intervention, which improves the degree of mechanization.

[0034] Specifically, the linear motion drive device 7 includes a cylinder and an elastic top member 71. The elastic top member 71 is fixedly disposed at the free end of the cylinder. The cylinder is used to drive the elastic top member 71 to move to the end of the roller and squeeze the roller until the positioning tip 31 is half inserted into the end of the roller.

[0035] In this embodiment, an elastic top member 71 is used to squeeze one end of the roller to avoid the problem of roller deformation caused by rigid contact.

[0036] Of course, the cylinder in the above embodiments can also be replaced by a linear module driven by a motor, a hydraulic cylinder, etc.

[0037] In some embodiments, the chamfering drive device 1 can also drive the chamfering tool 2 to move up and down. The chamfering tool 2 and the positioning element 3 are mounted on the same support frame 9. The chamfering tool 2 is rotatably mounted on the support frame 9, and the positioning element 3 is fixedly mounted on the support frame 9. The chamfering drive device 1 can drive the support frame 9 to move up and down and back and forth (i.e., Figure 1 (Positive and negative directions of the x-axis).

[0038] The chamfering drive device 1 can take various forms, such as a cylinder, electric cylinder, hydraulic cylinder, etc., which can realize linear movement. It can also use a lead screw to convert the rotational motion of the motor into linear motion. In this embodiment of the invention, the device for driving lifting and forward and backward movement is not limited. That is, any device in the prior art that can realize the forward and backward movement and lifting of the support frame 9 can be applied to this embodiment of the invention.

[0039] In some embodiments, both the lower support 5 and the upper clamping member 61 are V-shaped blocks.

[0040] In some embodiments, the inner chamfer and the outer chamfer are integrated, the inner chamfer is a three-blade chamferer or a grinding head with a conical surface, and the outer chamfer includes a plurality of blades arranged circumferentially.

[0041] To further improve processing efficiency, along the y-axis (the y-axis is perpendicular to...) Figure 1 Multiple chamfering devices 2, lower support members 5, and elastic top members 71 are arranged side by side along the extension directions of the x-axis and z-axis. Each of the multiple chamfering devices 2 is equipped with a multiple rotary drive device, which is a motor. Each of the multiple elastic top members 71 is equipped with a cylinder, electric cylinder, or hydraulic cylinder. A stop bar 41 is also provided, which extends along the y-axis.

[0042] The processing method is as follows:

[0043] 1. The workpiece is placed onto the V-block by the transfer mechanism.

[0044] 2. The linear motion drive device 7 drives the elastic top member 71 to push the workpiece toward the positioning tip 31 and move it until the positioning tip 31 is half inserted into the end of the roller.

[0045] 3. The upper clamping component drive device 6 drives the upper clamping component to move down to press the workpiece, and the linear movement drive device 7 drives the elastic top component 71 to move backward.

[0046] 4. The stop lever driving device 4 drives the stop lever 41 to move down to a specific height, where the specific height refers to the contact with the workpiece surface or the existence of a small gap.

[0047] 5. The chamfering drive device 1 drives the positioning tip 31 to move backward and drives the support frame 9 to raise the chamfering device 2 to a certain height so that the chamfering device 2 is coaxial with the roller.

[0048] 6. The rotary drive device drives the chamfering machine 2 to rotate. The chamfering drive device 1 drives the support frame 9 to move the rotary drive device and the chamfering machine 2 slowly toward the roller. After moving to the set depth, the chamfering ends.

[0049] 7. All mechanisms are reset, awaiting the next cycle.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
