[0003] Existing guide wheel testing devices typically involve cyclically rotating the guide wheel to simulate its cyclic rolling motion and thus test its wear resistance. However, these devices lack the ability to adjust the pressure applied to the guide wheel to simulate cyclic rolling. Consequently, the existing testing methods cannot reflect the wear resistance of the guide wheel under different pressures during cyclic rolling, and the testing functionality needs improvement. Utility Model Content

[0004] The present invention aims to provide a testing device for guide wheels to solve the problem mentioned in the background art. Existing guide wheel testing devices typically involve cyclically driving the guide wheel to roll, thereby simulating the cyclic rolling of the guide wheel to test its wear resistance. However, existing guide wheel testing devices do not have the function of adjusting the pressure applied to the guide wheel to simulate cyclic rolling. Therefore, the existing testing method cannot reflect the wear resistance of the guide wheel under different pressures, and the testing function needs to be improved.

[0005] The technical solution adopted by this utility model to solve the technical problem is as follows: a test device for a guide wheel, comprising: a first lead screw module, which is horizontally arranged on a wall; a second lead screw module, which is vertically arranged on the first lead screw module, and a fixing block is drivenly connected to the second lead screw module, and a guide wheel is fixed on the fixing block by a plurality of fasteners; and a table, which is placed on the ground and corresponds to the bottom end of the guide wheel.

[0006] In some embodiments, the first lead screw module includes a first support plate, a first motor, a first ball screw, a first bearing seat, and a first nut seat. The first motor is disposed at one end of the first support plate and is drivenly connected to one end of the first ball screw. The first bearing seat is disposed at the other end of the first support plate and is rotatably connected to the other end of the first ball screw. The two sides of the first nut seat are slidably connected to slide rails disposed on both sides of the first support plate, and the middle part of the first nut seat is threadedly connected to the first ball screw.

[0007] In some embodiments, the second lead screw module includes a second support plate, a second motor, a second ball screw, a second bearing shaft seat, and a second nut seat. The second motor is disposed at the top of the second support plate and is drivenly connected to the top of the second ball screw. The second bearing shaft seat is disposed at the bottom of the second support plate and is rotatably connected to the bottom of the second ball screw. The two sides of the second nut seat are slidably connected to slide rails disposed on both sides of the second support plate, and the middle part of the second nut seat is threadedly connected to the second ball screw. The fixing block is fixedly connected to the second nut seat.

[0008] In some embodiments, the fixing block is provided with a plurality of first screw holes, the top of the guide wheel is provided with a mounting block, the mounting block is provided with a plurality of second screw holes, and each of the first screw holes on the fixing block is fixed to each of the second screw holes on the mounting block by the fastener.

[0009] In some embodiments, the fastener includes a bolt and a nut, the bolt being threadedly connected to the nut.

[0010] In some embodiments, a plurality of first connecting blocks are provided on the top and bottom sides of the first lead screw module, and each first connecting block is provided with a third screw hole for inserting an expansion screw.

[0011] In some embodiments, the testing device for the guide wheel further includes a control panel mounted on a wall.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, when testing the wear resistance of the guide wheel, the guide wheel is fixed to the fixed block with several fasteners to install the guide wheel. Then, the first lead screw module drives the second lead screw module to move back and forth laterally in a cyclical manner. When the second lead screw module is driven to move back and forth laterally in a cyclical manner, it drives the guide wheel on the fixed block to roll back and forth laterally on the table. This tests the wear condition of the guide wheel under the duration of cyclical rolling, and thus tests the wear resistance performance of the guide wheel. When it is necessary to adjust the pressure applied to the guide wheel to simulate wear resistance under cyclic rolling, the second lead screw module drives the fixed block to rise or fall a corresponding distance, thereby adjusting the tightness of the contact between the guide wheel connected to the fixed block and the table body. When the contact between the guide wheel and the table body is looser, the pressure applied to the guide wheel is smaller; when the contact between the guide wheel and the table body is tighter, the pressure applied to the guide wheel is larger. After adjusting the contact tightness between the guide wheel and the table body, the first lead screw module drives the second lead screw module to move laterally back and forth cyclically. The second lead screw module then drives the guide wheel connected to the fixed block to cyclically roll laterally back and forth on the table body, thus testing the wear condition of the guide wheel under corresponding pressure and rolling duration. This invention allows users to adjust the pressure applied to the guide wheel to test its wear resistance under different pressures and rolling durations, offering practical and efficient advantages.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0023] Please refer to the following: Figures 1 to 4 As shown, Figure 1 A schematic diagram of the overall structure of the test device 100 for the guide wheel; Figure 2 A schematic diagram of the test device 100 for guide wheels with the table body 50 removed; Figure 3 This is a schematic diagram of the structure of the first lead screw module 10; Figure 4 This is a schematic diagram of the structure in which the second lead screw module 20 and the guide wheel 40 are in a split state.

[0024] This utility model provides the following technical solution: a test device 100 for a guide wheel, comprising: a first lead screw module 10, which is horizontally arranged on a wall; a second lead screw module 20, which is vertically arranged on the first lead screw module 10, and a fixing block 30 is connected to the second lead screw module 20 for transmission, and a guide wheel 40 is fixed on the fixing block 30 by a plurality of fasteners 302; and a table 50, which is placed on the ground and corresponds to the bottom end of the guide wheel 40.

[0025] In the guide wheel testing device 100 provided in this embodiment, when the guide wheel 40 is tested for wear resistance, the guide wheel 40 is fixed to the fixed block 30 by a number of fasteners 302, thus installing the guide wheel 40. Then, the first lead screw module 10 drives the second lead screw module 20 to move back and forth laterally. When the second lead screw module 20 is driven to move back and forth laterally, the guide wheel 40 on the fixed block 30 is driven to roll back and forth laterally on the table 50, thereby testing the wear condition of the guide wheel 40 under the duration of cyclic rolling, so as to test the wear resistance performance of the guide wheel 40. When it is necessary to adjust the pressure applied to the guide wheel 40 to simulate the wear resistance under cyclic rolling, the second lead screw module 20 drives the fixed block 30 to rise or fall a corresponding distance, so as to drive the guide wheel 40 connected to the fixed block 30 to adjust the tightness of the contact with the table body 50. When the contact between the guide wheel 40 and the table body 50 is loose, the pressure applied to the guide wheel 40 is small. When the contact between the guide wheel 40 and the table body 50 is tight, the pressure applied to the guide wheel 40 is large. After adjusting the contact tightness between the guide wheel 40 and the table body 50, the first lead screw module 10 drives the second lead screw module 20 to move back and forth laterally in a cyclic manner. Then, the second lead screw module 20 drives the guide wheel 40 connected to the fixed block 30 to roll back and forth laterally on the table body 50 to test the wear condition of the guide wheel 40 under the corresponding pressure for a certain period of time. In this invention, users can adjust the pressure applied to the guide wheel 40 to test the wear resistance of the guide wheel 40 under different pressures for a certain period of time, which has the advantages of being practical and efficient.

[0026] In some embodiments, the first lead screw module 10 includes a first support plate 102, a first motor 103, a first ball screw 104, a first bearing seat 105, and a first nut seat 106. The first motor 103 is disposed at one end of the first support plate 102 and is connected to one end of the first ball screw 104. The first bearing seat 105 is disposed at the other end of the first support plate 102 and is rotatably connected to the other end of the first ball screw 104. The two sides of the first nut seat 106 are slidably connected to slide rails disposed on both sides of the first support plate 102, and the middle part of the first nut seat 106 is threadedly connected to the first ball screw 104.

[0027] In specific implementation: When the first lead screw module 10 drives the second lead screw module 20 to move laterally, the first motor 103 drives the rotation of one end of the first ball screw 104, and the first bearing seat 105 supports the rotation of the other end of the first ball screw 104. When the first ball screw 104 is driven to rotate, it drives the first nut seat 106 to move laterally on the slide rails on both sides of the first support plate 102. When the first nut seat 106 moves laterally, it drives the second lead screw module 20 to move laterally. With this arrangement, the first lead screw module 10 can effectively drive the second lead screw module 20 to move laterally.

[0028] In some embodiments, the second lead screw module 20 includes a second support plate 201, a second motor 202, a second ball screw 203, a second bearing seat 204, and a second nut seat 205. The second motor 202 is disposed at the top end of the second support plate 201 and is connected to the top end of the second ball screw 203. The second bearing seat 204 is disposed at the bottom end of the second support plate 201 and is rotatably connected to the bottom end of the second ball screw 203. The two sides of the second nut seat 205 are slidably connected to the slide rails disposed on both sides of the second support plate 201, and the middle part of the second nut seat 205 is threadedly connected to the second ball screw 203. A fixing block 30 is fixedly connected to the second nut seat 205.

[0029] In specific implementation: When the guide wheel 40, connected to the transmission fixing block 30 of the second lead screw module 20, rises or falls, the second motor 202 drives the rotation at the top of the second ball screw 203, and the second bearing shaft seat 204 supports the rotation at the bottom of the second ball screw 203. When the second ball screw 203 is driven to rotate, it drives the second nut seat 205 to move vertically on the slide rails on both sides of the second support plate 201. When the second nut seat 205 moves vertically, it drives the guide wheel 40 connected to the fixing block 30 to rise or fall, thereby adjusting the contact tightness between the guide wheel 40 and the table body 50, and thus adjusting the pressure of the guide wheel 40 rolling on the table body 50. Through this setting, the second lead screw module 20 can effectively drive and adjust the contact tightness between the guide wheel 40 and the table body 50.

[0030] In some embodiments, a plurality of first screw holes 301 are distributed on the fixing block 30, and a mounting block 401 is provided on the top of the guide wheel 40. A plurality of second screw holes 4011 are distributed on the mounting block 401. Each of the first screw holes 301 on the fixing block 30 is fixed to each of the second screw holes 4011 on the mounting block 401 by fasteners 302.

[0031] In practice: when the guide wheel 40 is mounted on the fixed block 30 for wear resistance testing, each of the first screw holes 301 on the fixed block 30 is fixed to each of the second screw holes 4011 on the mounting block 401 using fasteners 302, thus completing the installation. This setup allows the guide wheel 40 to be mounted on the fixed block 30 for wear resistance testing.

[0032] In some embodiments, the fastener 302 includes a bolt 3021 and a nut 3022, wherein the bolt 3021 and the nut 3022 are threadedly connected.

[0033] In specific implementation: When fixing the first screw hole 301 on the fixing block 30 and the second screw hole 4011 on the mounting block 401 with fasteners 302, bolts 3021 can be inserted into the first screw hole 301 on the fixing block 30 and the second screw hole 4011 on the mounting block 401. Then, the nut 3022 is screwed onto the bolt 3021 at the bottom of the mounting block 401. Thus, the first screw hole 301 on the fixing block 30 and the second screw hole 4011 on the mounting block 401 are fixed by fasteners 302. With this setting, the guide wheel 40 can be effectively installed on the fixing block 30 by fasteners 302 to undergo wear resistance testing.

[0034] In some embodiments, a plurality of first connecting blocks 101 are provided on the top and bottom sides of the first lead screw module 10, and each first connecting block 101 is provided with a third screw hole 1011 for inserting an expansion screw.

[0035] In specific implementation: The first lead screw module 10 is used to install on the wall. When installing the first lead screw module 10 on the wall, expansion screws can be inserted into the third screw holes 1011 on each of the first connecting blocks 101 on the top and bottom sides of the first lead screw module 10 to connect with the wall, thereby fixing the first lead screw module 10 to the wall for use. Through this setting, the first lead screw module 10 can be effectively installed on the wall.

[0036] In some embodiments, the test device 100 for the guide wheel further includes a control panel 60, which is mounted on a wall and electrically connected to the first lead screw module 10 via wiring. The control panel 60 is also electrically connected to the second lead screw module 20 via a retractable wiring.

[0037] In practical implementation: The control panel 60 is used for manual operation by the user. The control panel 60 controls the operation of the first lead screw module 10 and the second lead screw module 20 according to the user's control commands. This configuration allows the control panel 60 to be used by the user to control the operation of the first lead screw module 10 and the second lead screw module 20.

[0038] In some embodiments, the top and bottom sides of the control panel 60 are provided with a plurality of second connecting blocks 601, and each second connecting block 601 is provided with a fourth screw hole 6011 for inserting an expansion screw.

[0039] In practical implementation: The control panel 60 is used to install on the wall. When installing the control panel 60 on the wall, expansion screws can be inserted into the fourth screw holes 6011 on each of the second connecting blocks 601 on the top and bottom sides of the control panel 60 to connect it to the wall, so as to realize the use of the control panel 60 on the wall. With this setting, the control panel 60 can be effectively installed on the wall.
