Description

Technical Field

[0001] This utility model belongs to the field of roller technology, and in particular relates to an automatic roller shaft head assembler. Background Technology

[0002] Currently, during the assembly of the shaft head and the roller, an electric heating coil is first used to heat the roller end, increasing the size of the roller end to facilitate the sliding of the shaft head into place. Then, the shaft head is manually slid into place at the roller end. Due to the high temperature of the electric heating coil and the roller end, this manual operation poses certain risks. Furthermore, manually aligning the shaft head and roller coaxially takes considerable time, increasing the workload for operators. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an automatic roller shaft head assembler with high operational safety and fast coaxial alignment speed.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: an automatic roller shaft head assembler, comprising a first base, a carrier plate, a hydraulic cylinder, a positioning sleeve, a rotating sleeve, ball bearings, and a guide rod. The cylinder body of the hydraulic cylinder is fixedly mounted on the first base, the carrier plate is fixedly mounted on the piston rod of the hydraulic cylinder, the positioning sleeve is fixedly mounted on the carrier plate, and a positioning groove is provided inside the positioning sleeve. The rotating bodies of two ball bearings are fixedly sleeved on the positioning sleeve, and the rotating sleeve is fixedly sleeved on the cages of the two ball bearings. The positioning sleeve has countersunk holes arranged in a circular array that communicate with the positioning grooves. The guide rod is slidably mounted in the countersunk holes. A first hemispherical head is provided at the outer end of the guide rod. A spring is sleeved on the guide rod, and the inner and outer ends of the spring act on the countersunk hole step surface and the first hemispherical head, respectively. The rotating sleeve has connecting rods arranged in a circular array that correspond one-to-one with the guide rods, and a second hemispherical head that cooperates with the first hemispherical head is fixedly mounted at the inner end of the connecting rod.

[0005] Furthermore, the planar end of the second hemispherical head is flush with the inner wall of the rotating sleeve.

[0006] Furthermore, it also includes four telescopic guide rods arranged in a rectangular pattern, with both ends of the four telescopic guide rods fixedly connected to the first base and the carrier plate, respectively.

[0007] Furthermore, the carrier plate and the rotating sleeve are respectively and fixedly installed on the first cylindrical rod and the second cylindrical rod.

[0008] Furthermore, a first limiting retaining ring and a second limiting retaining ring are respectively fixedly sleeved on the first cylindrical rod and the second cylindrical rod.

[0009] Furthermore, the connecting rod is fixedly covered with an anti-slip sleeve.

[0010] Compared with the prior art, the advantages of this utility model are: after the shaft head is clamped in the positioning sleeve, the shaft head can be slidably installed in the roller by the hydraulic cylinder, realizing automated coaxial alignment and installation, reducing the assembly labor intensity of operators, and improving the safety of assembly operations.

[0015] The present invention will now be described in detail with reference to specific embodiments:

[0016] like Figures 1 to 3 The automatic roller shaft assembly device shown includes a first base 1, a carrier plate 2, a hydraulic cylinder 3, a positioning sleeve 4, a rotating sleeve 5, ball bearings 51, and a guide rod 6. The cylinder body of the hydraulic cylinder 3 is fixedly mounted on the first base 1, the carrier plate 2 is fixedly mounted on the piston rod of the hydraulic cylinder 3, the positioning sleeve 4 is fixedly mounted on the carrier plate 2, and a positioning groove 41 is provided inside the positioning sleeve 4. The rotating bodies of the two ball bearings 51 are fixedly sleeved on the positioning sleeve 4, and the rotating sleeve 5 is fixedly sleeved on the retaining body of the two ball bearings 51. On the frame, the positioning sleeve 4 has four countersunk holes arranged in a circular array, communicating with the positioning groove 41. The guide rod 6 is slidably installed in the countersunk holes. The outer end of the guide rod 6 is provided with a first hemispherical head 61. A spring 62 is sleeved on the guide rod 6. The inner and outer ends of the spring 62 act on the countersunk hole step surface and the first hemispherical head 61, respectively. The rotating sleeve 5 has connecting rods 7 arranged in a circular array, corresponding one-to-one with the guide rod 6. The inner end of the connecting rod 7 is fixedly installed with a second hemispherical head 71 that cooperates with the first hemispherical head 61. The first base 1 can be fixedly installed on the swing arm mechanism. After the first base 1 drives the carrier plate 2 and the positioning sleeve 4 to rotate 90° relative to the electric heating coil 9, it is convenient for the operator to clamp the shaft head 10 in the positioning sleeve 4.

[0017] The flat end of the second hemispherical head 71 is flush with the inner wall of the rotating sleeve 5, so that both the first hemispherical head 61 and the second hemispherical head 71 are in contact with arc surfaces, which has the advantage of smooth transition and can avoid jamming problems.

[0018] It also includes four telescopic guide rods 31 arranged in a rectangular pattern. The two ends of the four telescopic guide rods 31 are fixedly connected to the first base 1 and the carrier plate 2, respectively. The four telescopic guide rods 31 can reduce the load force on the piston rod of the hydraulic cylinder 3, making the connection structure between the carrier plate 2 and the first base 1 stronger.

[0019] The carrier plate 2 and the rotating sleeve 5 are respectively and fixedly installed on the first cylindrical rod 21 and the second cylindrical rod 52. The first cylindrical rod 21 and the second cylindrical rod 52 have the same diameter. The limiting sleeve 23 is slidably installed on the first cylindrical rod 21. When the limiting sleeve 23 is simultaneously fitted on the first cylindrical rod 21 and the second cylindrical rod 52, it can restrict the rotation of the rotating sleeve 5 relative to the positioning sleeve 4, so that the operator does not need to hold the connecting rod 7 to restrict the rotation of the rotating sleeve 5.

[0020] A first limiting ring 22 and a second limiting ring 53 are respectively fixedly sleeved on the first cylindrical rod 21 and the second cylindrical rod 52. The first limiting ring 22 can prevent the limiting sleeve 23 from frequently impacting the carrier plate 2 and causing scratches on its surface. The second limiting ring 53 can limit the extreme position of the rightward movement of the limiting sleeve 23, and prevent the limiting sleeve 23 from being too large when sleeved on the second cylindrical rod 52. The limiting sleeve 23 is equally sleeved on the first cylindrical rod 21 and the second cylindrical rod 52. By referring to the positions of the first cylindrical rod 21 and the second cylindrical rod 52, the positional state of the first hemispherical head 61 and the second hemispherical head 71 can also be determined.

[0021] The connecting rod 7 is fixedly covered with an anti-slip sleeve 72, which can make the operator hold the operating connecting rod 7 more stably and avoid slippage.

[0022] The right end of roller 9 is fixedly clamped, and the left end of roller 9 is heated inside the electric heating coil 9. Rotating sleeve 5 via connecting rod 7 causes the second hemisphere 71 to be in a non-contact state with the first hemisphere 61. The assembly of the first hemisphere 61 and guide rod 6 moves outward under the force of spring 62. The second hemisphere 71 abuts against the inner wall of rotating sleeve 5, and the inner end of guide rod 6 disengages from positioning groove 41. The left end of shaft head 10 is slidably installed in positioning groove 41. Rotating rotating sleeve 5 via connecting rod 7 causes the second hemisphere 71 to align with the first hemisphere 61. 1. Upon contact, the combination of the first hemispherical head 61 and the guide rod 6 overcomes the elasticity of the spring 62 and moves downward. The inner end of the guide rod 6 contacts the shaft head 10 and presses it firmly. The corresponding first cylindrical rod 21 and second cylindrical rod 52 are coaxial. The sliding limiting sleeve 23 makes it equally spaced on the first cylindrical rod 21 and second cylindrical rod 52, restricting the rotation of the rotating sleeve 5. This controls the piston rod of the hydraulic cylinder 3 to extend, pushing the carrier plate 2, the positioning sleeve 4, and the clamped shaft head 10 to move to the right and slide into the left end of the heated roller 9. The sliding limiting sleeve 23 separates it from the second cylindrical rod 52. Rotating the rotating sleeve 5 releases the pressure of the second hemispherical head 71 on the first hemispherical head 61. The combination of the first hemispherical head 61 and the guide rod 6 rebounds outward under the elastic force of the spring 62. The guide rod 6 releases the pressing force on the shaft head 10. At this time, the piston rod of the hydraulic cylinder 3 retracts, and the positioning sleeve 4 separates from the shaft head 10.
