Description

Technical Field

[0001] This utility model belongs to the technical field of transmission frame structure, specifically relating to a transmission frame for detecting or processing shaft-type workpieces. Background Technology

[0002] During the inspection or processing of workpieces, a transfer rack is often required to automatically feed the workpieces. Traditional conveyor belts or roller transport racks are not suitable for shaft workpieces because shaft workpieces themselves will roll randomly, which is not conducive to accurate transmission and may even cause transmission chaos.

[0003] In the prior art, patent publication CN 214731461 U discloses a stainless steel pipe transfer rack comprising a transfer rack and a support frame. The transfer rack is rotatably mounted on one edge of the top surface of the support frame. The interior of the transfer rack includes a limit slot, a sleeve, a limit baffle, and a protective frame. The sleeve is welded to one end of the transfer rack, the limit slots are evenly distributed on the outer surface of the sleeve, the limit baffle is rotatably mounted on one edge of the top surface of the transfer rack, and the protective frame is slidably inserted on the top surface of the limit baffle. The interior of the support frame includes a control switch, a drive motor, a drive gear, a threaded rod, a connecting device, a support plate, and a positioning shaft. The threaded rod is symmetrically slidably mounted on both sides of one end of the support frame. Although the above technical solution achieves the neat and orderly storage of axial workpieces such as stainless steel pipes, the transfer rack itself does not have the ability to transfer workpieces, and can only be transported by an external transport vehicle. Moreover, the workpieces are completely stacked close together, which is not conducive to the independent completion of individual workpiece operations during inspection or processing. Utility Model Content

[0005] In response to the deficiencies of the prior art, the utility model proposes a transmission stand for shaft workpiece inspection or processing, which has a simple structure and can be used to accommodate and transport shaft workpieces in an orderly manner, with each workpiece accommodated separately, which is conducive to accurate transmission and independent completion of inspection or processing operations for individual workpieces.

[0006] 2. Specific technical solutions

[0007] A transfer table for inspecting or processing shaft-type workpieces includes a mounting base, on which a transfer frame mechanism and two fixed placement frame structures are mounted.

When the transfer bayonet structure on the transfer plate is aligned with the shaft-type workpiece placed in the placement bayonet structure via a sliding drive device, and then the transfer plate is raised via a lifting drive device to neatly replace and insert the shaft-type workpiece into the transfer bayonet structure, the sliding drive device moves the transfer plate forward to align with the next placement bayonet structure position. Simultaneously, the lifting drive device lowers the transfer plate, causing the shaft-type workpiece to fall into the next placement bayonet structure position, thus realizing the transfer operation of the shaft-type workpieces. The entire transfer operation is neat and orderly, and each workpiece remains in a separated placement state, which is beneficial for accurate transfer and for each workpiece to independently complete the inspection or processing operation.

[0029] Example:

[0030] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown: A transfer table for inspecting or processing shaft-type workpieces, taking the circular runout detection of shaft-type workpieces as an example, includes a mounting base 1. A transfer frame mechanism 2 and two fixed placement frame structures 3 are mounted on the mounting base 1, respectively positioned on both sides of the transfer frame mechanism 2. A detection equipment frame 4 is also mounted at one end of the mounting base 1. The transfer frame mechanism 2 and the two fixed placement frame structures 3 pass through the detection equipment frame 4. Circular runout telescopic detection tables 5 are evenly installed on the detection equipment frame 4. The circular runout telescopic detection tables 5 are positioned between the transfer frame mechanism 2 and the fixed placement frame structures 3. Between the two fixed placement frame structures 3, and on the circular runout telescopic detection table 5, a circular runout detection device is installed. The circular runout detection device is an elastic sensor device, or a dial indicator can also be used. The detection equipment frame 4 is also equipped with two telescopic rolling support frames 6 and a rotary drive mechanism 7. The two telescopic rolling support frames 6 are arranged opposite to each other on the outside of the two fixed placement frame structures 3. The output end of the rotary drive mechanism 7 is located above the telescopic rolling support frames 6. A clamping device 8 is also slidably installed on the top of the detection equipment frame 4. The clamping device 8 is arranged opposite to the circular runout telescopic detection table 5.

[0031] The aforementioned fixed placement frame structure 3 is provided with a fixed connection support leg assembly 31 and a support plate 32. The bottom of the fixed connection support leg assembly 31 is fixedly mounted on the mounting base 1 or the testing equipment frame 4, and the support plate 32 is fixedly mounted on the top of the fixed connection support leg assembly 31. Placement bayonet structures 33 are evenly spaced on the upper side of the support plate 32 for placing shaft-type workpieces. Each shaft-type workpiece is placed independently and is sufficiently stable.

[0032] The aforementioned transmission frame mechanism 2 includes a lifting drive device 21 and a sliding seat plate 22. The output end of the lifting drive device 21 is connected to the bottom of the sliding seat plate 22. The lifting drive device 21 is installed on the mounting base 1 or the testing equipment frame 4. Similarly, the sliding seat plate 22 is set above the mounting base 1 or the testing equipment frame 4. At least two slide rail structures 23 are provided on the upper surface of the sliding seat plate 22. A sliding drive device 24 is also installed on the sliding seat plate 22. Both the lifting drive device 21 and the sliding drive device 24 are hydraulic cylinders or pneumatic cylinders.

[0033] A sliding mounting base 25 is slidably mounted on the slide rail structure 23. The output end of the sliding drive device 24 is connected to the sliding mounting base 25. Two transmission support feet 26 are mounted on the sliding mounting base 25, and a transmission upright plate 27 is mounted on the transmission support feet 26. The transmission upright plate 27 is detachably mounted on the sliding mounting base 25 through the transmission support feet 26. The upper and lower ends of the transmission support feet 26 are detachably mounted by screws, thus realizing the sequential connection of the vertical lifting mechanism, the horizontal sliding mechanism and the transmission upright plate 27 of the transmission frame mechanism 2. The two transmission upright plates 27 are arranged in parallel and side by side, and both transmission upright plates 27 are parallel to the support upright plate 32. Transmission bayonet structures 28 are evenly spaced on the upper side of the transmission upright plate 27 to hold and lift shaft-type workpieces and complete the conveying of workpieces to one end. The transmission bayonet structure 28 and the placement bayonet structure 33 are spaced at the same distance, and the transmission bayonet structure 28 and the placement bayonet structure 33 have the same shape. Specifically, the transmission bayonet structure 28 and the placement bayonet structure 33 are inverted triangular, inverted trapezoidal, or semi-circular arc shapes.

[0034] The frame 4 of the above-mentioned testing equipment is shaped like a square in the middle. The circular jump telescopic testing table 5 is composed of a telescopic control device connected to the testing table, and the testing table is provided with corresponding workpiece slots.

[0035] The aforementioned telescopic rolling support frame 6 consists of a support plate frame 61, a telescopic cylinder 62, and a roller head 63. The telescopic cylinder 62 is located on the side of the support plate frame 61, and the roller head 63 is connected to the output end of the telescopic cylinder 62. The output end of the telescopic cylinder 62 and the roller head 63 are vertically upward, and two freely rotating rollers are installed on the roller head 63. The workpiece is stuck between the two rollers and rotates freely.

[0036] Two rotary drive mechanisms 7 are installed on the frame 4 of the aforementioned testing equipment. The two rotary drive mechanisms 7 act on both ends of the shaft-like workpiece. Each rotary drive mechanism 7 is provided with a sliding mounting seat 71. The sliding mounting seat 71 has a slide rail structure, on which a sliding support frame 72 is slidably mounted. A sliding drive hydraulic cylinder 73 is also installed at the rear end of the sliding mounting seat 71. The output end of the sliding drive hydraulic cylinder 73 is connected to the sliding support frame 72. A center mounting seat 74 is installed on the upper part of the sliding support frame 72. The center mounting seat 74 is locked on the sliding support frame 72 and slides vertically. A vertical drive hydraulic cylinder 75 is installed at the bottom of the sliding support frame 72. The output end of the vertical drive hydraulic cylinder 75 is connected to the bottom of the center mounting seat 74. A center is rotatably mounted on the center mounting seat 74.

[0037] Furthermore, a rotary drive mechanism 7 can be installed on the frame 4 of the testing equipment. The rotary drive mechanism 7 acts on one end of the shaft-type workpiece, that is, it is connected to the rolling roller through the motor. The motor and the rolling roller follow the pitching rotation of the mounting frame. Thus, when the rolling roller presses on the end face of the workpiece, it drives the workpiece to rotate. When the workpiece is removed, the rolling roller is raised to facilitate the removal of the workpiece. The pitching rotation of the mounting frame can be controlled by a hydraulic cylinder, a pneumatic cylinder or a motor.

[0038] The aforementioned clamping device 8 includes a sliding mounting bracket 81 and a hydraulic cylinder device 82. The hydraulic cylinder device 82 is installed at the lower center of the sliding mounting bracket 81. A sliding rail structure is provided on the top wall of the U-shaped frame of the measuring equipment frame 4. The sliding mounting bracket 81 is slidably mounted on this sliding rail structure. The sliding mounting bracket 81 can be moved by a hydraulic cylinder, gear and rack, or lead screw structure controller. The piston rod of the hydraulic cylinder device 82 is vertically downward. A clamping support plate 83 is installed at the bottom of the piston rod of the hydraulic cylinder device 82. A clamping slot is provided at the bottom of the clamping support plate 83, and elastic steel balls are evenly distributed on the clamping slot for contact with the surface of shaft-type workpieces.

[0039] The principle of implementation is as follows: Shaft-type workpieces are evenly placed in the placement bayonet structure 33 at the feeding end of the fixed placement frame structure 3. Each shaft-type workpiece corresponds to a placement bayonet structure 33 position, which can stably and neatly accommodate the shaft-type workpieces. The sliding drive device 24 controls the transfer bayonet structure 28 on the transfer plate 27 to align with the shaft-type workpiece placed in the placement bayonet structure 33. Then, the lifting drive device 21 controls the transfer plate 27 to rise, neatly replacing the shaft-type workpieces into the transfer bayonet structure 28. When the sliding drive device 24 controls the transfer plate 27 to move forward to align with the next placement bayonet structure 33, the lifting drive device 21 controls the transfer plate 27 to fall down, and the shaft-type workpiece falls into the next placement bayonet structure 33, thereby realizing the transfer operation of shaft-type workpieces. The entire transfer operation is neat and orderly, and each workpiece is always kept in a separated and accommodated state, which is conducive to accurate transfer and independent completion of detection or processing operations for individual workpieces.

[0040] After the shaft workpiece is moved to the position of the circular runout telescopic detection table 5, the circular runout telescopic detection table 5 and the telescopic rolling support frame 6 raise each part of the shaft workpiece, and the rotation of the shaft workpiece is controlled by the rotary drive mechanism 7, and the shaft workpiece to be tested is pressed by the clamping device 8, so that the detection is more stable and accurate, thus completing the automatic detection of the circular runout of the shaft workpiece. Its overall manufacturing cost and usage cost are relatively low, the process is simple and the accuracy is high, and the detection efficiency is high.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims.
