Description

Technical Field

[0001] This utility model relates to the field of machining auxiliary equipment technology, and in particular to a trolley transfer platform. Background Technology

[0002] In machining production sites, workpiece transfer operations are often involved between two machines. For example, between two sets of machine tools, the semi-finished workpiece after the previous process (such as the workpiece after drilling) needs to be transferred to another machine in the same production area at a certain distance for further processing (such as grinding the workpiece with a grinding machine).

[0003] In existing technologies, workpieces are typically transferred to the next workstation using overhead cranes or trolleys within the workshop. Overhead cranes have drawbacks, including high investment costs and the need for specialized operators, thus limiting their application, especially in small-scale production environments. Trolley transfers involve workers placing one or more workpieces in the trolley's loading tray, then manually moving the workpieces to the next workstation. This method requires manual handling throughout the process, causing inconvenience and hindering efficiency. Considering these factors, providing a transfer platform that offers convenience to workers and improves work efficiency is highly necessary. Utility Model Content

[0004] In order to overcome the shortcomings of the existing production process where transferring workpieces between two machines in the same production area is limited by technology, as described in the background art, this utility model provides a trolley transfer platform that, under the combined action of related structures, allows workers in two production processes to easily transfer a workpiece-laden frame between the two processes simply by operating a power switch. Furthermore, it can lift the workpieces within the frame to a greater height, bringing convenience to workers in both processes and correspondingly improving work efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A trolley transfer platform includes an electric linear slide, multiple material frames, a base plate, and a displacement mechanism and a lifting mechanism. The electric linear slide is horizontally fixedly mounted on the base plate. The displacement mechanism includes a motor reducer, a screw, a fixed housing, and a push block. The fixed housing has a guide groove at its upper end. The motor reducer is fixedly mounted on the outer side of one side of the fixed housing. One end of the screw is fixedly mounted to the rotating shaft of the motor reducer, and the other end of the screw is rotatably mounted inside the other side of the fixed housing. The push block has a threaded hole at its lower part, and the lower end of the push rod is threadedly connected to the screw. A shaft is fixedly mounted on the outer side of the lower end of the fixed housing. The lower end of the shaft is rotatably mounted on the sliding block of the electric linear slide, and the upper end of the sliding block is adjacent to the outer side of the lower end of the fixed housing. The lifting mechanism has at least two sets, each set including a motor reducer A, a screw A, a lifting shell, a limiting plate, and a lifting rod; one side of the lifting shell has a limiting groove, the motor reducer A is fixedly installed inside the upper part of the lifting shell, the limiting plate has a screw hole, the limiting plate is horizontally movable inside the lifting shell, the upper end of the screw A is fixedly installed at the lower end of the rotating shaft of the motor reducer A, the lower end of the screw A is rotatably installed inside the lower part of the lifting shell, the screw A and the screw hole of the limiting plate are connected together by threads, one side of the lifting rod and one side of the limiting plate are fixedly installed together, and the other side of the lifting rod is located outside the lifting shell; the lifting shells of the two sets of lifting structures are respectively fixedly installed on the base plates at both ends of the electric screw slide table.

[0007] Furthermore, the upper end of the material frame has an open structure, and handles are fixedly installed on the upper parts of its front and rear sides respectively.

[0008] Furthermore, the front and rear end widths of the push block are smaller than the front and rear widths of the guide groove, and the upper part of the push block is located outside the upper end of the fixed shell.

[0009] Furthermore, the outer diameter of the limiting plate is smaller than the inner diameter of the lifting shell.

[0010] Furthermore, the front-to-back width of the lifting rod is smaller than the front-to-back width of the limiting groove.

[0011] Furthermore, a support plate is fixedly installed at the upper end of the lifting rod and is located at the outer end of the lifting shell.

[0012] Furthermore, the lifting rods and support plates of the two lifting mechanisms are in a face-to-face structure.

[0013] Furthermore, the area of ​​the fixed shell and the area of ​​the support plate are greater than the area of ​​the lower end of the material frame.

[0014] Furthermore, when the support plate is at the upper dead point, its upper end height is consistent with the height of the loading and unloading stations between the two devices in the production area; when the support plate is at the lower dead point, its upper end height is consistent with the upper end height of the fixed shell.

[0015] Furthermore, a connecting plate is fixedly installed on one side of the sliding block of the electric linear slide, a fixing block is fixedly installed on one side of the connecting plate, and a magnet is attracted to the front end of the fixing block and the fixing shell.

[0016] Compared with the prior art, the advantages of this utility model are: the workers of the two production processes only need to operate the power switch to easily transfer the workpiece between the two workstations. Since the bearing is installed between the sliding block and the lower end of the fixed shell, the fixed shell can be easily removed by changing the angle after it is between the two workstations. Under the action of the lifting mechanism, the fixed shell can be easily raised and lowered after it reaches the two workstations, which brings convenience to the workers in placing the material frame and improves the work efficiency accordingly.

The fixed shell 22 has a rectangular guide groove 221 horizontally at the upper center and an opening at the lower center of the left side. The motor reduction device M1 is fixedly mounted outside the lower center of the left side of the fixed shell 22, and its rotating shaft rotates within the opening. The bearing seat 23 is fixedly mounted inside the fixed shell 22. At the lower right end, the left end of the screw 21 and the right end of the rotating shaft are fixedly installed together. The right end of the screw 21 is fixedly installed inside the bearing inner ring of the bearing seat 23. The push block 24 has a threaded hole in the lower middle part. The lower end of the push rod 24 and the screw 21 are connected together by threads. A shaft 25 is fixedly installed at the lower outer middle part of the fixed housing 22. A bearing seat B26 is fixedly installed in the mounting groove (a circular mounting groove is pre-machined) in the middle part of the sliding block of the electric screw slide table. The lower end of the shaft 25 is fixedly installed inside the bearing inner ring of the bearing seat B26, and the upper end of the sliding block and the lower outer part of the fixed housing 22 are spaced apart. There are two sets of lifting mechanisms 3. Each lifting mechanism includes a motor reduction device AM2, a screw A31, and a bearing seat.

[0023] A32, hollow lifting shell 33, limiting plate 34, lifting rod 35; The inner end of the lifting shell 33 has a rectangular limiting groove 331 running from top to bottom. The lower end of the bearing housing A32 is fixedly installed in the lower middle of the lifting shell 33. The motor reduction device AM2 is fixedly installed in the upper middle of the lifting shell 33. The limiting plate 34 has a screw hole in the middle, and the limiting plate 34 is horizontally movable within the lifting shell 33. The upper end of the screw A31 is fixedly installed in the lower end of the shaft of the motor reduction device AM2, and the lower end of the screw A31 is fixedly installed in the inner ring of the bearing housing A32. Rod A31 and limiting plate 34 are connected together by screw holes. One side of the "¬"-shaped lifting rod 35 and the middle of one end of the inner side of the limiting plate 34 are fixedly installed together, and the lifting rod 35 is located outside the lifting shell 33. The two sets of lifting structures 3 are fixedly installed on the bottom plates of the left and right sides of the electric screw slide table M. The two sets of lifting mechanisms 3 are respectively fixed on the ground between two machines in the same production area. The power module W1 and power switches K1, K2 and K3 are installed on the circuit board inside the component box 4. The component box 4 is installed in the electrical control box of the next production process.

[0024] Figure 1 , 2As shown in Figures 3 and 4, the upper end of the material frame 1 has an open structure, and handles 101 are fixedly installed on its front and rear upper ends respectively (for easy carrying by workers). The lifting rods 35 of the two lifting mechanisms are located on the inside and face each other. The front and rear widths of the push block 24 are smaller than the front and rear widths of the guide groove 221, and the upper part of the push block 24 is located outside the upper end of the fixed shell 22. The outer diameter of the limiting plate 34 is smaller than the inner diameter of the lifting shell 33. The front and rear widths of the lifting rod 35 are smaller than the front and rear widths of the limiting groove 331. A support plate 5 is fixedly installed on the upper end of the lifting rod. The area of ​​the fixed shell 22 and the area of ​​the support plate 5 are larger than the lower end area of ​​the material frame 1. When the support plate 5 is at the upper stop point, its upper height (higher than the height of the lifting shell) is consistent with the height of the loading and unloading stations between the two machines in the production area. When the support plate 5 is at the lower stop point, its upper height is consistent with the upper height of the fixed shell 22. A connecting plate 6 is fixedly installed at the upper middle of the right side of the sliding block of the electric linear slide table M. A fixing block is fixedly installed at the right side of the connecting plate 6. A permanent magnet block 7 is attracted to the upper end of the fixing block and the right side of the fixing shell 22 (to prevent the fixing shell from rotating along the bearing seat when the material frame is displaced). The power input terminals 1 and 2 of the voltage regulator circuit module W1 are connected to the two poles of the AC 220V power supply via wires. The power output terminal of the voltage regulator circuit module W1 is connected to the power input terminals 1 and 2 of the three power switches K1, K2, and K3 via wires. The power output terminals 3 and 4, and 5 and 6 of the three power switches K1, K2, and K3 are connected to the positive and negative and negative and positive power input terminals of the electric lead screw slide table M, the motor reduction device M1, and the motor reduction device AM2 via wires.

[0025] Figure 1 , 2As shown in Figures 3 and 4, after the AC 220V power supply enters the power input terminal of the voltage regulator module W1, the DC 36V power supply output from pins 3 and 4 of the voltage regulator module W1 enters the power input terminals of power switches K1, K2, and K3, and the power switches K1, K2, and K3 are energized. The working process of this new type is as follows: (1): After the worker in the previous process places the relevant processed workpieces in one of the material frames 1 (located in the loading station) and measures them, the worker drags the material frame 1 horizontally to the outside of the lifting shell 33 of the lifting mechanism on the left end, and then pushes it onto the fixed shell 22. Then, the worker rotates the fixed shell and the material frame 90 degrees along the bearing seat B26. At this time, the motor reduction device M1 is located on the left end, and the left end of the material frame 2 is located on the right end of the push block 24. Then, the permanent magnet block 7 is attracted to the upper end of the fixed block (steel material) and the right end of the fixed shell (steel material) (to prevent the material frame from rotating); the worker places the second material frame 1 on the loading station for loading. (2): After the voice prompt from the previous worker, the worker in the next production process moves the handle of the power switch S3 to the right, and pins 1 and 2 and pins 5 and 6 of the power switch S3 are connected respectively. The positive and negative power input terminals of the motor reducer AM2 are energized, and its shaft drives the screw A31 to rotate clockwise. The external thread of the screw A31 acts on the limit plate 34 and the support plate, and the material frame 2 descends. When the material frame 2 descends to the lower stop point, the power switch S3 is turned off (if the material frame is too high, the operation will be relatively unstable, so the material frame needs to be lowered to change position). The worker moves the handle of the power switch S1 to the left, and pins 1 and 2 and pins 3 and 4 of the power switch S1 are connected respectively. The positive and negative power input terminals of the electric screw slide M are connected, and the sliding block of the electric screw slide M drives the material frame 2 to move to the right stop point. Then the worker turns off the power switch S1. (3); In the next process, the worker moves the power switch S2 handle to the left, and pins 1 and 2 and pins 3 and 4 of the power switch S2 are connected respectively. The positive and negative power input terminals of the motor reduction device M1 are energized, and its shaft drives the screw 21 to rotate counterclockwise. The external thread of the screw 21 acts on the push block 24 to move to the right end, pushing the material frame onto the support plate 5 of the lifting mechanism on the right end (at this time, the power switch S2 is turned off). (4): The next worker moves the power switch S3 handle to the left, and pins 1 and 2 and pins 3 and 4 of the power switch S3 are connected respectively. The positive and negative power input terminals of the motor reduction device AM2 are energized, and its shaft drives the screw A31 to rotate counterclockwise. The external thread of the screw A31 acts on the limit plate 34 and the support plate, and the material frame 2 rises. When the material frame 2 rises to the upper stop point, the power switch S3 is turned off. The worker drags the material frame 2 horizontally to the upper end of the lifting shell 33 of the right end lifting mechanism, and drags it to the unloading station, so that the next worker can take out the workpiece to be processed from the material frame.(5): In the next process, the worker places the third empty material frame 1 after the previous processing on the support plate 5. The worker moves the handle of the power switch S3 to the right, and pins 1 and 2 and pins 5 and 6 of the power switch S3 are connected respectively. The negative and positive power input terminals of the motor reduction device AM2 are energized, and its shaft drives the screw A31 to rotate clockwise. The external thread of the screw A31 acts on the limit plate 34 and the support plate, and the material frame 2 descends. When the material frame 2 descends to the lower stop point, the power switch S3 is turned off. The worker rotates the fixed shell and the material frame 90 degrees along the bearing seat B26. At this time, the motor reduction device M1 is located on the right side, and the right side of the material frame 2 is located on the left side of the push block 24. Then, the permanent magnet block 7 is attracted to the upper end of the fixed block (steel material) and the left side of the fixed shell (steel material) (to prevent the material frame from rotating when it is displaced). (6): In the next process, the worker moves the handle of the power switch S1 to the right, and pins 1 and 2 and pins 5 and 6 of the power switch S1 are connected respectively. The positive and negative power input terminals of the electric screw slide M are connected, and the sliding block of the electric screw slide M drives the material frame 2 to move to the left stop point. Then the worker turns off the power switch S1. (7): The worker in the previous process removes the third material frame 1 by hand. Then, the worker in the next process moves the handle of the power switch S3 to the left. Pins 1 and 2 and pins 3 and 4 of the power switch S3 are connected respectively. The positive and negative power input terminals of the motor reduction device AM2 are energized, and its shaft drives the screw A31 to rotate counterclockwise. The external thread of the screw A31 acts on the limit plate 34 and the support plate 2 to raise the height. After the support plate 2 rises to the upper stop point, the power switch S3 is turned off. Then, the worker in the previous process removes the magnet. At this moment, the material frame 2 is dragged horizontally to the upper end of the lifting shell 33 of the left lifting mechanism. The worker drags the material frame to the loading station, which makes it convenient for the worker in the previous process to put the workpiece to be processed into the material frame. Similar to the above process (1)-(7), the third material frame can be transferred to the next process to realize the cyclical production of loading and unloading.

[0026] Figure 1 , 2 As shown in Figures 3 and 4, through the above-described method, the workers in the two production processes of this new invention only need to operate the power switch to easily transfer the workpiece between the two workstations. Since a bearing is installed between the sliding block and the lower end of the fixed shell, it is convenient to change the angle of the fixed shell after it reaches the two workstations and remove the fixed shell. Under the action of the lifting mechanism, the fixed shell can be easily raised and lowered after it reaches the two workstations, which brings convenience to the workers in placing and taking out the material frame and improves the work efficiency accordingly. Figure 4 In the middle, the voltage regulator circuit module W1 is a finished product of AC 220V power supply to DC 36V power supply module (5KW); the electric ball screw slide M is a finished product of long stroke 2KW electric ball screw slide; the electric reduction device M1 and the electric reduction device AM2 are finished products of motor gear reduction with a power of 1KW.
