Description

Technical Field

[0001] The invention relates to the technical field of elevator wheel processing, in particular to a clamping device for processing aluminum alloy elevator wheels. Background Art

[0002] An elevator is a permanent transport device that serves specific floors within a building, with its car running on at least two rows of rigid tracks perpendicular to the horizontal plane or inclined at an angle of less than 15° to the vertical. There are also stepped models, with treads mounted on tracks that run continuously, commonly known as escalators or moving walkways. Elevator pulleys are a crucial component in elevators, transmitting power. Their structure generally consists of standard bearings, roller bearing seats, and a rubber or plastic outer ring. After forming, they often require a series of steps such as grinding, cutting, and polishing. For stability during processing, they are generally clamped in a fixture.

[0003] The existing device cannot clamp and fix workpieces with inner rings of different diameters, and its practicality is low. Moreover, when the diameter of the inner ring of the workpiece differs greatly from that of the outer ring, when processing the outer ring, the clamping is not stable enough due to the long force arm, resulting in low processing efficiency. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides: a clamping device for processing aluminum alloy elevator wheels, comprising a fixed base having a circular plate-like structure, and a support plate arranged on the top of the fixed base, wherein the bottom of the support plate is fixedly connected to the top of the fixed base;

[0005] A processing table having a circular structure and a sliding opening on the top of the processing table, wherein the bottom of the processing table is fixedly connected to the top of the support plate;

[0006] A mobile control plate having a circular plate-like structure and a connection frame arranged on the outside of the mobile control plate, wherein the connection frame is provided in multiple groups and is fixedly connected to the mobile control plate, and a hydraulic cylinder is connected to the bottom of the mobile control plate;

[0007] The clamping support device is used to clamp and fix the workpiece. The clamping support device includes an adjusting plate, a bending rod and a tightening device. The bending rod is rotated and opened by the movement of the adjusting plate, and the tightening device squeezes and tightens the inner wall of the workpiece.

[0008] Preferably, the sliding openings are provided in multiple groups and are evenly distributed on the processing table, the movable end of the hydraulic cylinder passes through the processing table and is slidingly connected to the processing table, the movable end of the hydraulic cylinder extends to the top of the processing table and is fixedly connected to the movable control plate, and the fixed end of the hydraulic cylinder is fixedly connected to the top of the fixed base.

[0009] Preferably, the end of the adjustment plate is rotatably connected to the connecting frame through a rotating shaft, the adjustment plate near the connecting frame passes through the sliding opening and is slidably connected to the inner wall of the sliding opening, and multiple groups of adjustment plates are provided and correspond one-to-one to the sliding openings.

[0010] Preferably, the clamping support device also includes a rotating seat, the rotating part of the rotating seat is rotatably connected to the side of the bending rod, and an auxiliary support device is installed on the side of the bending rod away from the rotating seat. The elevator wheel to be processed is placed on the outside of the tightening device, and the hydraulic cylinder is turned on to push the movable control plate. During the rising process of the movable control plate, the adjusting plate is driven to slide inside the sliding mouth, and the adjusting plate drives the bending rod to rotate around the rotating seat, thereby driving the tightening device and the auxiliary support device to open. The expansion amplitude of each group of bending rods can be adjusted by adjusting the rising distance of the movable control plate until the bending rod drives the tightening device to fit tightly against the inner wall of the inner ring of the workpiece, that is, the inner wall of the inner ring of the workpiece can be clamped and fixed, and workpieces with inner rings of different diameters can be clamped and fixed, which is more practical.

[0011] Preferably, the end of the adjustment plate away from the connecting frame is rotatably connected to one end of the bending rod through a rotating shaft, the fixed end of the rotating seat is fixedly connected to the outer side of the processing table, and the rotating seat is provided in multiple groups.

[0012] Preferably, the bottom of the bending rod extends to the bottom of the processing table, and the top of the bending rod is located above the processing table.

[0013] Preferably, the tightening device includes a tightening block, a device groove is provided on one side of the tightening block, an arc-shaped spring sheet is fixedly connected to the top of the tightening block, an arc-shaped extrusion plate is fixedly connected to the end of the arc-shaped spring sheet away from the tightening block, a rubber anti-slip strip is installed on the side of the arc-shaped extrusion plate away from the device groove, a circular hole is provided on the side of the arc-shaped extrusion plate close to the rubber anti-slip strip, an electric push rod is installed at the center position of the inner wall of the device groove, and a rolling device is installed on the movable end of the electric push rod.

[0014] Preferably, the side of the tightening block close to the device groove is fixedly connected to the top of the bending rod, and the rubber anti-slip strips are provided in multiple groups.

[0015] Preferably, the rolling device includes an arc-shaped lubricating shell, the interior of which is filled with lubricating oil. Since the interior of the arc-shaped lubricating shell is filled with lubricating oil, the outer wall of the rolling ball sticks to the inner wall of the arc-shaped lubricating shell. As the workpiece rotates, the rolling ball is driven to rotate along the arc-shaped lubricating shell, and the lubricating oil inside the arc-shaped lubricating shell is applied from the extrusion hole to the outer wall of the rolling ball, thereby increasing the lubrication between the rolling ball and the arc-shaped lubricating shell, so that the workpiece can be smoother when rotating. The outer side of the arc-shaped lubricating shell is fixedly connected to the movable end of the electric push rod, and the inner wall of the arc-shaped lubricating shell is evenly provided with extrusion holes. The inner wall of the arc-shaped lubricating shell is rotatably connected to a connecting column through a rotating bearing, and the outer side of the connecting column is sleeved and fixedly connected with a rolling The moving ball, the outer side of the rolling ball extends to the inner wall of the arc-shaped lubricating shell and is slidably connected to the inner wall of the arc-shaped lubricating shell. When the bending rod rotates around the rotating seat, it drives the arc-shaped extrusion plate to squeeze the inner wall of the inner ring of the workpiece. The arc-shaped spring sheet presses the arc-shaped extrusion plate against the inner wall of the inner ring of the workpiece through elastic force. When the clamped workpiece needs to be rotated, the electric push rod is turned on, the electric push rod extends and pushes the arc-shaped lubricating shell and the rolling ball to slide out of the circular hole. The electric push rod pushes the rolling ball to contact the inner wall of the inner ring of the workpiece. At this time, the workpiece can be rotated, and the friction between the inner wall of the inner ring of the rotating workpiece and the rolling ball is reduced, so the workpiece can be rotated during the clamping process, which is convenient for adjusting the processing angle of the workpiece and improving the processing efficiency.

[0016] Preferably, the auxiliary support device includes a shell, which is sleeved on the bending rod and fixedly connected to the bending rod, and the inner wall of the shell is rotatably connected to a hydraulic telescopic rod through a rotating bracket. The hydraulic telescopic rod can be extended and shortened according to different outer ring diameters. The position of the suction cup can be changed by adjusting the length of the hydraulic telescopic rod, which can adapt to workpieces with different outer ring diameters, thereby improving the adaptability of the device. The movable end of the hydraulic telescopic rod is rotatably connected to an arc support plate through a rotating support seat, and a suction cup is installed on the side of the arc support plate away from the rotating support seat. When the inner ring diameter of the workpiece to be processed is greatly different from the outer ring diameter, the suction cup is used to adsorb on the bottom position of the outer ring of the workpiece before processing the workpiece. At this time, the bottom of the workpiece close to the outer ring is auxiliary supported by the hydraulic telescopic rod and the suction cup, and a triangular support is formed by the hydraulic telescopic rod and the tightening device, and its supporting force is strong, which can improve the stability of the workpiece during processing.

[0017] The present invention provides a clamping device for processing aluminum alloy elevator wheels. It has the following beneficial effects:

[0018] 1. This clamping device for processing aluminum alloy elevator wheels is used to install a clamping support device and a movable control plate. The elevator wheel to be processed is sleeved on the outside of the tightening device, and the hydraulic cylinder is turned on to push the movable control plate. During the rising process of the movable control plate, the adjusting plate is driven to slide inside the sliding port. The adjusting plate drives the bending rod to rotate around the rotating seat, thereby driving the tightening device and the auxiliary support device to open. The expansion amplitude of each group of bending rods can be adjusted by adjusting the rising distance of the movable control plate until the bending rod drives the tightening device to fit tightly against the inner wall of the inner ring of the workpiece, that is, the inner wall of the inner ring of the workpiece can be clamped and fixed. Workpieces with inner rings of different diameters can be clamped and fixed, and the practicability is good.

[0019] 2. This clamping device for processing aluminum alloy elevator wheels is installed with a rolling device and a tightening device. When the bending rod rotates around the rotating seat, it drives the arc-shaped extrusion plate to squeeze the inner wall of the inner ring of the workpiece. The arc-shaped spring sheet presses the arc-shaped extrusion plate against the inner wall of the inner ring of the workpiece through elastic force. When the clamped workpiece needs to be rotated, the electric push rod is turned on, the electric push rod extends and pushes the arc-shaped lubrication shell and the rolling ball to slide out of the circular hole. The electric push rod pushes the rolling ball to contact the inner wall of the inner ring of the workpiece. At this time, the workpiece can be rotated, and the friction between the inner wall of the inner ring of the rotating workpiece and the rolling ball is reduced. The workpiece can be rotated during the clamping process, which is convenient for adjusting the processing angle of the workpiece and improving the processing efficiency.

[0020] 3. This clamping device for processing aluminum alloy elevator wheels, through the installation of an auxiliary support device, when the diameter of the inner ring of the workpiece to be processed is greatly different from the diameter of the outer ring, before the workpiece is processed, a suction cup is used to adsorb on the bottom position of the outer ring of the workpiece. At this time, the bottom of the workpiece close to the outer ring is auxiliary supported by the hydraulic telescopic rod and the suction cup. The hydraulic telescopic rod and the tightening device form a triangular support, which has a strong supporting force and can improve the stability of the workpiece during the processing.

[0021] 4. This clamping device for processing aluminum alloy elevator wheels is equipped with a hydraulic telescopic rod and a suction cup. The hydraulic telescopic rod can be extended or shortened according to different outer ring diameters. The position of the suction cup can be changed by adjusting the length of the hydraulic telescopic rod. It can adapt to workpieces with different outer ring diameters and improve the adaptability of the device.

[0022] 5. This clamping device for processing aluminum alloy elevator wheels is installed through the rolling device. Since the interior of the arc-shaped lubricating shell is filled with lubricating oil, the outer wall of the rolling ball is attached to the inner wall of the arc-shaped lubricating shell. As the workpiece rotates, the rolling ball is driven to rotate along the arc-shaped lubricating shell. The lubricating oil inside the arc-shaped lubricating shell is applied to the outer wall of the rolling ball from the extrusion hole, which can increase the lubrication between the rolling ball and the arc-shaped lubricating shell, so that the workpiece can rotate more smoothly.

[0034] See also Figures 1-6The present invention provides a technical solution: a clamping device for processing an aluminum alloy elevator wheel, comprising a fixed base 1 having a circular plate-like structure, and a support plate 2 arranged on the top of the fixed base 1, wherein the bottom of the support plate 2 is fixedly connected to the top of the fixed base 1;

[0040] The clamping support device 8 further includes a rotating seat 84 , a rotating portion of the rotating seat 84 is rotatably connected to the side of the bending rod 82 , and an auxiliary support device 85 is installed on the side of the bending rod 82 away from the rotating seat 84 .

[0041] One end of the adjustment plate 81 away from the connection frame 6 is rotatably connected to one end of the bending rod 82 through a rotating shaft. The fixed end of the rotating seat 84 is fixedly connected to the outer side of the processing table 3. There are multiple groups of rotating seats 84.

[0042] The bottom of the bending rod 82 extends to the bottom of the processing table 3 , and the top of the bending rod 82 is located above the processing table 3 .

[0043] The tightening device 83 includes a tightening block 831, a mounting groove 832 is provided on one side of the tightening block 831, an arc-shaped spring piece 833 is fixedly connected to the top of the tightening block 831, and an arc-shaped extrusion plate 834 is fixedly connected to the end of the arc-shaped spring piece 833 away from the tightening block 831, a rubber anti-slip strip 835 is installed on the side of the arc-shaped extrusion plate 834 away from the mounting groove 832, and a circular hole 836 is provided on the side of the arc-shaped extrusion plate 834 close to the rubber anti-slip strip 835, an electric push rod 837 is installed at the center position of the inner wall of the mounting groove 832, and a rolling device 838 is installed on the movable end of the electric push rod 837.

[0044] The side of the tightening block 831 close to the installation groove 832 is fixedly connected to the top of the bending rod 82, and multiple groups of rubber anti-slip strips 835 are provided.

[0045] The rolling device 838 includes an arc-shaped lubricating shell 8381, the interior of the arc-shaped lubricating shell 8381 is filled with lubricating oil, the outer side of the arc-shaped lubricating shell 8381 is fixedly connected to the movable end of the electric push rod 837, and the inner wall of the arc-shaped lubricating shell 8381 is evenly provided with extrusion holes 8382. The inner wall of the arc-shaped lubricating shell 8381 is rotatably connected to a connecting column 8383 through a rotating bearing, and a rolling ball 8384 is sleeved and fixedly connected to the outer side of the connecting column 8383. The outer side of the rolling ball 8384 extends to the inner wall of the arc-shaped lubricating shell 8381 and is slidably connected to the inner wall of the arc-shaped lubricating shell 8381.

[0046] When in use, the elevator wheel to be processed is placed on the outside of the tightening device 83, and the hydraulic cylinder 7 is turned on to push the movable control plate 5. During the rising process of the movable control plate 5, the adjusting plate 81 is driven to slide inside the sliding port 4, and the adjusting plate 81 drives the bending rod 82 to rotate around the rotating seat 84, thereby driving the tightening device 83 and the auxiliary support device 85 to open. By adjusting the rising distance of the movable control plate 5, the expansion amplitude of each group of bending rods 82 can be adjusted until the bending rod 82 drives the tightening device 83 to fit tightly against the inner wall of the inner ring of the workpiece, that is, the inner wall of the inner ring of the workpiece can be clamped and fixed, and workpieces with inner rings of different diameters can be clamped and fixed, which is very practical.

[0047] When the bending rod 82 rotates around the rotating seat 84, it drives the arc-shaped extrusion plate 834 to squeeze the inner wall of the inner ring of the workpiece. The arc-shaped spring sheet 833 presses the arc-shaped extrusion plate 834 against the inner wall of the inner ring of the workpiece through elastic force. When the clamped workpiece needs to be rotated, the electric push rod 837 is turned on. The electric push rod 837 extends and pushes the arc-shaped lubrication shell 8381 and the rolling ball 8384 to slide out of the circular hole 836. The electric push rod 837 pushes the rolling ball 8384 to contact the inner wall of the inner ring of the workpiece. At this time, the workpiece can be rotated. The friction between the inner wall of the inner ring of the rotating workpiece and the rolling ball 8384 is reduced, and the workpiece can be rotated during the clamping process, which is convenient for adjusting the processing angle of the workpiece and improving the processing efficiency.

[0048] Since the arc-shaped lubricating shell 8381 is filled with lubricating oil, the outer wall of the rolling ball 8384 is attached to the inner wall of the arc-shaped lubricating shell 8381. As the workpiece rotates, the rolling ball 8384 is driven to rotate along the arc-shaped lubricating shell 8381. The lubricating oil inside the arc-shaped lubricating shell 8381 is smeared from the extrusion hole 8382 to the outer wall of the rolling ball 8384, which can increase the lubrication between the rolling ball 8384 and the arc-shaped lubricating shell 8381, so that the workpiece can rotate more smoothly.

[0049] See also Figures 1-9 The present invention provides a technical solution: on the basis of embodiment one, the auxiliary support device 85 includes a shell 851, the shell 851 is sleeved on the bending rod 82 and fixedly connected to the bending rod 82, the inner wall of the shell 851 is rotatably connected to the hydraulic telescopic rod 853 through the rotating bracket 852, the movable end of the hydraulic telescopic rod 853 is rotatably connected to the arc support plate 855 through the rotating support seat 854, and a suction cup 856 is installed on the side of the arc support plate 855 away from the rotating support seat 854.

[0050] During use, when the diameter of the inner ring of the workpiece being processed is significantly different from the diameter of the outer ring, before processing the workpiece, the suction cup 856 is used to adsorb on the bottom position of the outer ring of the workpiece. At this time, the hydraulic telescopic rod 853 and the suction cup 856 are used to auxiliary support the bottom of the workpiece close to the outer ring. The hydraulic telescopic rod 853 and the tightening device 83 form a triangular support, which has a strong supporting force and can improve the stability of the workpiece during the processing process.

[0051] The hydraulic telescopic rod 853 can be extended or shortened according to different outer ring diameters. By adjusting the length of the hydraulic telescopic rod 853, the position of the suction cup 856 can be changed, which can adapt to workpieces with different outer ring diameters and improve the adaptability of the device.
