[0002] The carrier roller shaft is an important accessory of a belt conveyor. In the related art, the lathe processing device takes a long time to clamp and loosen the carrier roller shaft when processing the carrier roller shaft, and the operator has a large working strength. The reason is that the carrier roller shaft turning is a kind of part that needs long-time and large-batch cutting processing, which involves the flat head, chamfer and slotting of the carrier roller shaft. Since the outer diameter of the carrier roller shaft is relatively small, the length of the carrier roller shaft during blanking is controlled relatively accurately. Therefore, the feed amount during turning is relatively small, and the turning efficiency of the carrier roller shaft is relatively high, which causes the operator to frequently clamp and loosen the carrier roller shaft.

[0056] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application.

[0057] A roller shaft fixing device 100 of an embodiment of the present application is described below with reference to the drawings. As shown in Figures 1 to 10 , the roller shaft fixing device 100 according to the embodiment of the present application includes a first wheel body 1, a chucking head, an elastic member, and a first driver 6.

[0058] The first wheel body 1 has a first hole body 11 extending in a first direction. The first direction can be a left-right direction, which is shown by an arrow in the drawing. The axial direction of the first wheel body 1 is the left-right direction. For example, the first wheel body 1 is a belt pulley, and the first hole body 11 extends in the left-right direction.

[0059] The clamping head includes a clamping pipe for accommodating the supporting roller shaft and a plurality of clamping segments, the clamping pipe extends along the first direction, and the plurality of clamping segments are arranged at the end of the clamping pipe in a circumferential direction and can be deformed in the radial direction of the clamping pipe to clamp the supporting roller shaft. The clamping head is movably arranged in the first hole body 11 along the first direction so that the clamping head has a first position and a second position. When the clamping head moves from the first position to the second position, the plurality of clamping segments move inward in the radial direction of the clamping pipe to clamp the supporting roller shaft. For example, the clamping pipe extends along the left-right direction, and the plurality of clamping segments are located at the end of the clamping pipe.

[0060] The elastic member can be elastically deformed in the first direction, the elastic member is connected with the clamping head and can drive the clamping head to move from the first position to the second position. The first driver 6 can drive the clamping head to move from the second position to the first position. For example, the elastic member can be elastically deformed in the left-right direction, and the first position is located on the left side of the second position.

[0061] According to the supporting roller shaft fixing device 100 of the embodiment of the present application, the clamping head is movably arranged in the first hole body 11 along the first direction so that the clamping head has a first position and a second position. Specifically, the clamping segment is an elastic member (metal member) that can be elastically deformed in the radial direction, the first position is a placement position suitable for placing the supporting roller shaft into the clamping head (the clamping pipe and the plurality of clamping segments), and the second position is a clamping position at which the plurality of clamping segments move inward in the radial direction of the clamping pipe to clamp the supporting roller shaft.

[0062] By arranging the elastic member that can drive the clamping head to move from the first position to the second position and the first driver 6 that can drive the clamping head to move from the second position to the first position. Thus, when the supporting roller shaft needs to be placed, the first driver 6 is used to drive the clamping head to move from the second position to the first position, so that the supporting roller shaft is easily placed into the clamping head. After a preset time, the first driver 6 can be returned, and then the elastic member drives the clamping head to move from the first position to the second position, so that the plurality of clamping segments of the clamping head can move inward in the radial direction of the clamping pipe to clamp the supporting roller shaft. That is, during the entire process of clamping the supporting roller shaft, the worker only needs to place the supporting roller shaft into the clamping head at the first position, and when the supporting roller shaft needs to be fastened and taken out again, the worker does not need to manually clamp and loosen the supporting roller shaft, thereby saving time and effort and improving production efficiency.

[0063] Therefore, the supporting roller shaft fixing device 100 according to the embodiment of the present application has the advantage of facilitating the fixing and loosening of the supporting roller shaft.

[0064] As Figures 1 to 10As shown, in some embodiments, the outer surface of the clamping section includes an inclined section, which is a guide inclined surface at an angle to the first direction. During the movement of the clamping section along the first direction, the guide inclined surface guides the clamping section so that the clamping section deforms radially in the clamping tube. For example, the outer surface of the inclined section is a guide inclined surface at an angle to the left and right directions, and the guide inclined surface is inclined to the right and inward. The first position is located to the left of the second position. During the movement of the clamping section to the right, the guide inclined surface (which may contact the opening of the first hole 11 or the guide portion inside the first hole 11) guides the clamping section, causing the clamping section to move inward and clamp the idler roller shaft.

[0065] like Figures 1 to 8 As shown, the roller shaft fixing device 100 according to an embodiment of the present invention further includes a conical seat, which is disposed on the first wheel body 1 and extends into the first hole 11. The clamping head is slidably disposed in the conical seat along a first direction. The guide slope is a conical slope, and the conical seat has a conical hole that mates with the guide slope. Specifically, the inner wall surface of the clamping section is an arc surface extending along the first direction, and the inner diameter of the conical hole decreases in the first direction along the direction adjacent to the second position. The guide slope is a conical slope, so that the conical hole of the conical seat can guide the clamping section of the clamping head, thereby facilitating the inward contraction of the guide slope under the limitation of the conical hole when the clamping section moves towards the second position (clamping position) in the first direction. For example, the inner diameter of the conical hole decreases from left to right.

[0066] like Figures 1 to 8 As shown, in some embodiments, there are multiple clamping heads and tapered seats, with each clamping head corresponding to one of the tapered seats (tapered holes), and the multiple clamping heads are arranged sequentially along a first direction. Specifically, each clamping head has an elastic element that mates with it, and the first driver 6 can drive the multiple clamping heads to move in the first direction. The idler roller shaft can be placed inside the multiple clamping heads so that the multiple clamping heads can clamp the idler roller shaft to make the idler roller shaft more stable. For example, the multiple clamping heads are arranged sequentially along the left-right direction, and the multiple clamping heads can abut against each other in the left-right direction (first direction).

[0067] like Figures 1 to 5 As shown, the first actuator 6 includes a telescopic rod 61 extending along a first direction. The telescopic rod 61 is located on one side of the first wheel body 1 in the first direction and moves along the first direction. The telescopic rod 61 can drive the clamping head to move from a second position to a first position. For example, the telescopic rod 61 is located on the right side of the first wheel body 1 (first hole 11) and adjacent to the clamping head. The telescopic rod 61 can move in a left-right direction. After the telescopic rod 61 moves to the left and abuts against the clamping head, it drives the clamping head to move to the left so that the clamping head moves to the first position. For example, the first actuator 6 is a pneumatic cylinder or a hydraulic cylinder.

[0068] like Figures 1 to 5 , Figure 9 andFigure 10 As shown, in some embodiments, the plurality of locking heads includes a first locking head 2 and a second locking head 3, wherein the first locking head 2 is located in a first direction on the side of the second locking head 3 opposite to the telescopic rod 61. For example, both the first locking head 2 and the second locking head 3 are located within the first hole 11. The first locking head 2 is located to the left of the second locking head 3.

[0069] The first clamping head 2 includes a first clamping tube 21 and a plurality of first clamping sections 22. The plurality of first clamping sections 22 are located on the side of the first clamping tube 21 facing away from the telescopic rod 61 in a first direction. Each first clamping section 22 includes a first inclined section 23, the guide inclined surface of which contracts inward in the first direction along the direction adjacent to the telescopic rod 61. Specifically, each first clamping section 22 is connected to the first clamping tube 21 via an arc-shaped connecting section extending in the first direction, with adjacent connecting sections spaced apart. Adjacent first clamping sections 22 define a notch, thereby facilitating elastic deformation of the first clamping section 22 in the radial direction. For example, the plurality of first clamping sections 22 are located at the left end of the first clamping tube 21.

[0070] The second clamping head 3 includes a second clamping tube 31 and a plurality of second clamping sections 32. The plurality of second clamping sections 32 are located on the side of the second clamping tube 31 adjacent to the telescopic rod 61 in a first direction. Each second clamping section 32 includes a second inclined section 33, the guide inclined surface of which contracts inward in the first direction along the direction adjacent to the telescopic rod 61. Specifically, each second clamping section 32 is connected to the second clamping tube 31 via an arc-shaped connecting section extending in the first direction. Two adjacent second clamping sections 32 define a notch, thereby facilitating elastic deformation of the second clamping section 32 in the radial direction. For example, the plurality of second clamping sections 32 are located at the right end of the second clamping tube 31.

[0071] like Figure 7 and Figure 8 As shown, the plurality of conical seats include a first conical seat 4 and a second conical seat 5, wherein the first conical seat 4 is located in a first direction on the side of the second conical seat 5 opposite to the telescopic rod 61. For example, the first conical seat 4 is located to the left of the second conical seat 5.

[0072] The elastic element includes a first elastic element 71 and a second elastic element 72. For example, both the first elastic element 71 and the second elastic element 72 are springs.

[0073] The first hole 11 has an annular boss 12 located between the first conical seat 4 and the second conical seat 5. The annular boss 12 can block the first hole 11 and has a through hole.

[0074] like Figure 9As shown, the first clamping pipe 21 is provided with a spring cover 24 at one end thereof away from the first clamping section 22 in the first direction, the spring cover 24 is annular and defines a (annular) first stepped groove 25 towards the first clamping section 22 with the first clamping pipe 21. The first elastic member 71 is annularly arranged at the periphery of the first clamping pipe 21, and the two ends of the first elastic member 71 abut against the first stepped groove 25 and the first tapered seat 4 in the first direction, respectively. Specifically, the outer diameter of the spring cover 24 is greater than the outer diameter of the first clamping pipe 21, and the outer diameter of the spring cover 24 is matched with the inner diameter of the first hole body 11. Thus, under the elastic force of the first elastic member 71, the spring cover 24 can be pushed to move away from the side of the first clamping section 22, so that the first clamping head 2 can be moved to the second position. The annular boss 12 can limit the first clamping section 22. That is, the purpose of arranging the annular boss 12 is to provide a support surface for the pushing force of the first elastic member 71, so that the elastic force of the first elastic member 71 can effectively act on the first clamping head 2, so that the diameter of the inner hole of the first clamping section 22 is reduced to clamp the roller shaft.

[0075] The spring cover 24 is detachably arranged on the first clamping pipe 21. For example, the annular spring cover 24 is detachably mounted on the right end of the first clamping section 22 by bolts, the first stepped groove 25 faces the left side, and the first elastic member 71 can drive the first clamping head 2 to move to the right.

[0076] As shown, Figure 10 The second clamping pipe 31 and the second clamping section 32 are provided with an annular second guide section 34 therebetween, the second guide section 34 defines a second stepped groove 35 towards the annular boss 12 with the second clamping pipe 31, and the second elastic member 72 is annularly arranged at the periphery of the second clamping pipe 31. The two ends of the second elastic member 72 abut against the second stepped groove 35 and the annular boss 12 in the first direction, respectively, and the second clamping pipe 31 passes through the annular boss 12 away from the second clamping section 32 in the first direction and is adjacent to the spring cover 24, so that the first clamping head 2 can abut against the second clamping head 3. Specifically, the outer diameter of the second guide section 34 is greater than the outer diameter of the second clamping pipe 31. Thus, under the elastic force of the second elastic member 72, the second guide section 34 can be pushed to move away from the side adjacent to the second clamping section 32, so that the second clamping section 32 can be moved to the second position. The annular boss 12 can limit the first clamping section 22. For example, the annular spring cover 24 is detachably mounted on the right end of the first clamping section 22 by bolts, the first stepped groove 25 faces the left side, and the second elastic member 72 can drive the second clamping head 3 to move to the right.

[0077] As shown, Figure 7As shown, the first conical seat 4 has a first conical hole 43, which contracts inward in a first direction along the direction adjacent to the telescopic rod 61, and the first inclined section 23 of the first clamping section 22 fits into the first conical hole 43. For example, the first conical hole 43 contracts to the right and inward, that is, the inner radial direction of the first conical hole 43 decreases to the right, and the guide slope of the first inclined section 23 of the first clamping section 22 is inclined to the right and inward.

[0078] The first conical seat 4 includes a first flange section 41 and a first sleeve section 42. The first flange section 41 is detachably mounted on the first wheel body 1, defining a first conical hole 43. The first sleeve section 42 is located within the first bore 11. The first sleeve section 42 has a first circular hole 44 connected to the first conical hole 43, and a first clamping tube 21 fits into the first circular hole 44. Specifically, the inner diameter of the first conical hole 43 is greater than or equal to the inner diameter of the first circular hole 44 of the first sleeve section 42. The first flange section 41 is located outside the first bore 11 and is detachably mounted at the end of the first wheel body 1 by multiple bolts. The outer diameter of the first sleeve section 42 is adapted to the inner diameter of the first bore 11 so that the first sleeve section 42 extends into the first bore 11. The inner diameter of the first circular hole 44 of the first sleeve section 42 is adapted to the outer diameter of the first clamping tube 21 so that the first clamping tube 21 is suitable for insertion into the first circular hole 44 of the first sleeve section 42. For example, the first conical seat 4 is detachably provided at the left end of the first wheel body 1.

[0079] like Figure 8 As shown, the second conical seat 5 has a second conical hole 53, which tapers inward in a first direction along the direction adjacent to the telescopic rod 61, and the second inclined section 33 of the second locking section 32 fits into the second conical hole 53. For example, the second conical hole 53 tapers inward to the right, that is, the inner radial direction of the second conical hole 53 decreases to the right, and the guide slope of the second inclined section 33 of the second locking section 32 is inclined inward to the right.

[0080] The second taper seat 5 comprises a second flange section 51 and a second sleeve section 52. The second flange section 51 is detachably arranged on the first wheel body 1 and defines a second taper hole 53. The second sleeve section 52 is arranged in the first hole body 11 and has a second circular hole 54 connected with the second taper hole 53, and the second guide section 34 is fitted in the second circular hole 54. Specifically, the inner diameter of the second taper hole 53 is equal to or less than the inner diameter of the second circular hole 54 of the second sleeve section 52. The second flange section 51 is arranged outside the first hole body 11 and is detachably arranged on the end of the first wheel body 1 by means of a plurality of bolts. The outer diameter of the second sleeve section 52 is adapted to the inner diameter of the first hole body 11, so that the second sleeve section 52 extends into the first hole body 11. The inner diameter of the second circular hole 54 of the second sleeve section 52 is adapted to the outer diameter of the second guide section 34, so that the second guide section 34 is adapted to be put into the second circular hole 54 of the second sleeve section 52. For example, the first taper seat 4 is detachably arranged on the right end of the first wheel body 1.

[0081] As shown in Figure 5 the roller shaft fixing device 100 according to the embodiment of the present application further comprises a pressure sleeve 8 and a positioning rod 82.

[0082] The pressure sleeve 8 extends along a first direction, one end of the pressure sleeve 8 is connected with the telescopic rod 61, and the other end of the pressure sleeve 8 is adjacent to the clamping head. The extension direction of the positioning rod 82 is perpendicular to the first direction, the pressure sleeve 8 has a first slot 81 facing the clamping head, and the positioning rod 82 extends into the first slot 81. Specifically, the other end of the pressure sleeve 8 is adjacent to the second clamping head 3, and the positioning rod 82 plays a role of limiting the roller shaft in the first direction.

[0083] When the roller shaft needs to be placed, the telescopic rod 61 of the first driver 6 moves in the first direction along the direction adjacent to the second clamping head 3, so that the pressure sleeve 8 can move in the first direction along the direction adjacent to the second clamping head 3. The pressure sleeve 8 abuts against the second clamping head 3 and drives the second clamping head 3 to move to the first position in the first direction. In this process, the second clamping head 3 abuts against the first clamping head 2 and drives the first clamping head 2 to move to the first position. After the first clamping head 2 and the second clamping head 3 move to the first position against the elastic force of the first elastic member 71 and the second elastic member 72, the first clamping section 22 and the second clamping section 32 restore the original shape, which facilitates the placement of the roller shaft.

[0084] After the preset time, the telescopic rod 61 of the first driver 6 moves in the first direction away from the second clamping head 3, so that the first elastic member 71 and the second elastic member 72 can drive the first clamping head 2 and the second clamping head 3 to move to the second position in the first direction respectively. Thus, the first clamping head 2 and the second clamping head 3 can clamp the carrier roller shaft, and the positioning rod 82 extends into the constant pressure sleeve 8 from the first slot 81, so that the positioning rod 82 limits the carrier roller shaft in the first direction, and the first slot 81 can make the constant pressure sleeve 8 move in the first direction without interfering with the positioning rod 82, so that the carrier roller shaft fixing device 100 according to the embodiment of the application can be automatically high.

[0085] For example, when the carrier roller shaft needs to be placed, the telescopic rod 61 of the first driver 6 moves to the left, so that the constant pressure sleeve 8 moves to the left. The constant pressure sleeve 8 abuts against the second clamping head 3 and drives the second clamping head 3 to move to the first position on the left side, and in this process, the second clamping head 3 abuts against the first clamping head 2 and drives the first clamping head 2 to move to the first position on the left side. After the first clamping head 2 and the second clamping head 3 move to the first position, the carrier roller shaft can be placed. After a preset time, the telescopic rod 61 of the first driver 6 moves to the right, so that the first elastic member 71 and the second elastic member 72 can drive the first clamping head 2 and the second clamping head 3 to move to the second position on the right side in the first direction respectively.

[0086] The carrier roller shaft fixing device 100 according to the embodiment of the application further comprises a frame 9, a second driver and a controller.

[0087] The first wheel body 1 is rotatably arranged on the frame 9, and the axial direction of the first wheel body 1 is the first direction.
