Description

Technical Field

[0001] This utility model belongs to the field of roller surface repair technology, and in particular relates to a special mobile embossing drive for the roller of a motor vehicle inspection line dynamometer. Background Technology

[0002] In motor vehicle testing lines, dynamometers are used to simulate vehicle driving resistance and measure power performance. The tread pattern on the surface of the dynamometer rollers directly affects the transmission of friction between the tire and the rollers. After a period of use, the tread pattern may wear, deform, or be missing, causing the tire to slip on the rollers and resulting in distorted test data. At this time, it is necessary to repair the tread pattern on the roller surface.

[0003] Traditional repair methods involve disassembling and repairing or replacing the rollers, which is time-consuming and labor-intensive. Furthermore, the disassembly process can easily cause secondary damage to the rollers. After the repair is completed, it is necessary to readjust the parallelism between the roller groups and the coaxiality between the rollers and the power system. Therefore, developing online roller repair technology is essential for improving repair efficiency and saving labor costs.

[0004] Chinese utility model patent application number 202223319990.4 discloses a device for repairing the friction surface of an automotive dynamometer roller. It uses the principle of high-frequency electric spark discharge to perform hot-spot welding on the workpiece to increase the surface roughness of the automotive dynamometer roller. It is suitable for cases of deep wear or local defects. However, it has low repair efficiency for large-area surface wear and places high demands on the wear resistance of welding equipment and welding rods, as well as the operator's skill level.

[0005] Chinese utility model patent application number 201720148898.6 discloses a portable dynamometer roller engraving device that can be used on-site. The device uses an engraving needle traveling mechanism to drive the engraving needle assembly to move along the roller axis to repair the surface pattern of the roller. However, this device can only be used to repair surface patterns and cannot treat defects such as rust and welding slag on the roller surface, which will affect the engraving repair effect.

[0006] Therefore, there is a need for an online roller pattern repair device that is highly efficient, fully functional, widely adaptable, and easy to operate. Utility Model Content

[0007] The main technical problem this utility model aims to solve is to provide a special mobile embossing drive for the rollers of a dynamometer in a motor vehicle inspection line. By setting a detachable cutter head, it can be replaced according to the site conditions. It can pre-treat the plating layer, rust layer and residual welding slag on the roller, ensuring the surface repair effect. At the same time, it is equipped with a secondary machine component to precisely control the speed and direction of the roller, further improving the repair effect.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] A mobile embossing drive for a dynamometer roller in a motor vehicle inspection line includes a main unit and a secondary unit. The main unit includes a main frame with a sliding bracket slidably mounted on it. A sliding seat plate is slidably mounted on the sliding bracket, and a cutter head bracket is fixedly mounted on the sliding seat plate. A cutter head is detachably mounted at the bottom of the cutter head bracket, and the cutter head can be replaced according to operational requirements. The secondary unit includes a base frame with an upper bracket fixedly mounted on top of it. A drive motor is fixedly mounted on the upper bracket, and a drive shaft is rotatably mounted thereon. The drive motor and the drive shaft are connected by a transmission.

[0010] The following are further optimizations of the above technical solution by this utility model:

[0011] Two first slide rails are arranged parallel to each other at both ends of the bottom of the main frame. First sliders are fixedly installed at the positions corresponding to the first slide rails at both ends of the sliding bracket. The first sliders are slidably installed on the first slide rails.

[0012] Further optimization: Two second slide rails are arranged in parallel on the sliding bracket. The second slide rails are arranged perpendicularly to the first slide rail. A second slider is fixedly installed on the sliding base plate at the position corresponding to the second slide rail. The second slider is slidably installed on the second slide rail.

[0013] Further optimization: The cutter head support includes a support body, the bottom of which is fixedly connected to a sliding seat plate. A third slider is slidably mounted on the support body. A first nut and a first screw are fixedly installed at corresponding positions on the third slider and the support body, respectively. The first nut and the first screw are screwed together.

[0014] Further optimization: A fourth slider is slidably mounted on the third slider, and a cutter head is detachably mounted on the bottom of the fourth slider. The sliding directions of the third and fourth sliders are perpendicular to each other.

[0015] Further optimization: A sliding drive device is fixedly installed at the position corresponding to the sliding bracket above the main frame. The sliding drive device includes a sliding drive motor fixedly installed on the sliding bracket. The power output end of the sliding drive motor is connected to a reduction gearbox. The output end of the reduction gearbox is fixedly connected to a second lead screw.

[0016] Further optimization: The second lead screw is set parallel to the second slide rail, the second lead screw is rotatably mounted on the sliding bracket, and the second lead nut is fixedly installed on the cutter head bracket at the position corresponding to the second lead screw, and the second lead nut is screwed to the second lead screw.

[0017] Further optimization: A transmission device is provided at one end of the drive shaft corresponding to the drive motor, and the other end of the transmission device is fixedly connected to the drive motor.

[0018] Further optimization: A set of driving wheels is fixedly installed on the drive shaft at a position outside the transmission device, and a tensioning wheel is also provided on the upper bracket at a position corresponding to the set of driving wheels.

[0019] Further optimization: The auxiliary unit also includes a control device, which is fixedly mounted on the upper bracket and electrically connected to the drive motor.

[0020] The present invention adopts the above technical solution and has the following beneficial effects:

[0021] This invention utilizes the combined design of slide rails and sliders to allow the cutter head to move freely along the axial and radial directions of the roller. The equipment can repair multiple rollers within the same roller group with a single installation, reducing the time required for moving and installing the equipment and improving work efficiency. At the same time, the cutter head can also be adjusted vertically, allowing the equipment to adapt to rollers at different heights and improving its versatility.

[0022] The detachable cutter head of this invention allows for quick disassembly and replacement. When there are weld points or rust residue on the roller surface, the milling cutter or grinding cutter can be replaced to pre-treat the roller surface before engraving and repair, without the need for other equipment. This saves time and manpower while ensuring the quality of the repair.

[0023] When the main unit of this invention is working, the roller is disconnected from the transmission connection of the detection line. Instead, the roller is driven to rotate by the auxiliary unit. The speed and direction of the roller are precisely controlled by the control device, which works closely with the cutter head of the main unit to avoid the roller speed being too fast or too slow, thus preventing it from affecting the repair effect.

[0024] The auxiliary unit of this utility model has different types of transmission wheels installed on its drive shaft, which can be matched with different types of testing lines. It uses the original transmission chain or transmission belt of the testing line for power transmission, without the need for additional matching and installation, thus saving operating costs.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0031] like Figure 1-2 As shown, a mobile embossing drive for a dynamometer roller in a motor vehicle inspection line includes a main unit 1 and a secondary unit 2. The main unit 1 is installed on the motor vehicle inspection line to perform surface treatment, pattern repair, and other operations on the dynamometer roller. The secondary unit 2 is connected to the transmission components of the dynamometer and provides external power during operation, precisely controlling the roller's speed and direction. It works in conjunction with the main unit 1 to complete the repair work and ensure the repair quality.

[0032] The main unit 1 includes a main frame 101, which is a rectangular frame structure assembled from profiles. Its length direction corresponds to the axial direction of the roller. A sliding bracket 102 is slidably mounted on the main frame 101. A sliding seat plate 103 is slidably mounted on the sliding bracket 102. A cutter head bracket 104 is fixedly mounted on the sliding seat plate 103. A cutter head 105 is detachably mounted at the bottom of the cutter head bracket 104. The cutter head 105 can be replaced according to operational requirements.

[0033] Two first slide rails 106 are arranged parallel to each other at both ends of the bottom of the main frame 101 along its width direction. A first slider 107 is fixedly installed at both ends of the sliding bracket 102 at positions corresponding to the first slide rails 106. The first slider 107 is slidably installed on the first slide rails 106, so that the sliding bracket 102 can slide along the width direction of the main frame 101.

[0034] The sliding bracket 102 is arranged along the length of the main frame 101. Two second slide rails 116 are arranged parallel to the length of the main frame 101 on the sliding bracket 102. A second slider 117 is fixedly arranged on the sliding seat plate 103 at a position corresponding to the second slide rails 116. The second slider 117 is slidably mounted on the second slide rails 116. The cutter head bracket 104 slides along the length of the main frame 101 under the drive of the sliding seat plate 103.

[0035] The first slide rail 106 and the second slide rail 116 are arranged vertically, so that the cutter head 105 can move along the axial and radial directions of the roller respectively. For a group of rollers, the main frame 101 can complete the repair of all rollers in the group in one installation, saving the time of moving and installing the equipment and improving work efficiency.

[0036] Limiting devices are also provided at both ends of the first slide rail 106 and the second slide rail 116. The limiting devices are limiting baffles (not shown in the drawings) installed at both ends of the first slide rail 106 and the second slide rail 116 to prevent the first slider 107 and the second slider 117 from falling off the slide rail, which would cause the equipment to malfunction.

[0037] like Figure 4 As shown, the cutter head bracket 104 includes a bracket body 108. The bottom of the bracket body 108 is fixedly connected to the sliding seat plate 103. A sliding groove is provided on the top of the bracket body 108 along the vertical direction. A third slider 109 is slidably installed on the sliding groove. A sliding groove is also provided on the third slider 109 along the width direction of the main frame 101. A fourth slider 118 is slidably installed on the sliding groove. A cutter head 105 is detachably installed at the bottom of the fourth slider 118.

[0038] A first nut 110 is fixedly connected to the side of the third slider 109 near the support body 108. A first lead screw 111 is fixedly connected to the support body 108 at a position corresponding to the first nut 110. The first nut 110 and the first lead screw 111 are screwed together. When the first lead screw 111 rotates, it drives the first nut 110 to move up and down, thereby driving the third slider 109 to move up and down.

[0039] In this embodiment, the top end of the first lead screw 111 extends out of the upper surface of the support body 108. By manually rotating the top end of the first lead screw 111, the vertical position of the third slider 109 can be adjusted. In addition to this embodiment, the top end of the first lead screw 111 can also be connected to an external power source such as a drive motor to realize the automatic adjustment of the vertical position of the third slider 109, so that the equipment can adapt to rollers at different heights and further improve the versatility of the equipment.

[0040] The fourth slider 118 is connected to the third slider 109 through a lead screw and nut structure. By rotating the lead screw, the fourth slider 118 slides on the third slider 109, thereby driving the cutter head 105 to achieve fine-tuning of its position. Its lead screw and nut structure is the same as that of the first lead screw 111 and the first nut 110, and will not be described in detail here.

[0041] Since the current methods for repairing rollers include not only engraving but also spot welding, if the roller has been repaired by spot welding in the early stage, there will be weld residue on its surface. If it is not treated, it will affect the effect of engraving repair. At the same time, the plating and rust layers on the roller will also affect the repair effect. In this case, it is necessary to replace the grinding tool or milling cutter to pre-treat the roller surface.

[0042] The 105 type of cutter head can be replaced with a grinding cutter, milling cutter, or embossing cutter according to the needs of the roller repair operation. The grinding cutter, milling cutter, and embossing cutter are all mature structures in the prior art and can be purchased on the market. The staff can quickly replace them according to the needs on site, which will not be described in detail in this application.

[0043] In this embodiment, the cutter head 105 and the fourth slider 118 are connected by bolts and nuts, which can not only ensure the connection strength, but also enable the quick replacement of the cutter head 105, thus ensuring the repair quality while improving work efficiency.

[0044] like Figure 1 As shown, a sliding drive device is fixedly installed above the main frame 101 at a position corresponding to the sliding bracket 102. This device is used to drive the cutter head bracket 104 to move the cutter head 105 along the length of the main frame 101. During the movement, the cutter head 105 contacts the surface of the roller to complete the surface repair.

[0045] The sliding drive device includes a sliding drive motor 112 fixedly mounted on a sliding bracket 102. The power output end of the sliding drive motor 112 is connected to a reduction gearbox 113. The output end of the reduction gearbox 113 is fixedly connected to a second lead screw 115. The reduction gearbox 113 reduces the speed and increases the torque of the rotational power output by the sliding drive motor 112, and after completing the reversal, transmits it to the second lead screw 115 to drive the second lead screw 115 to rotate.

[0046] The sliding drive motor 112 and the gearbox 113 are selected and purchased and installed according to the actual operation requirements. They are both mature products in the prior art and will not be described in detail in this application.

[0047] The second lead screw 115 is set along the length of the main frame 101. Both ends of the second lead screw 115 are rotatably mounted on the sliding bracket 102 through bearing seats. The second lead screw nut 114 is fixedly installed on the cutter head bracket 104 at the position corresponding to the second lead screw 115. The second lead screw nut 114 is screwed to the second lead screw 115. The sliding drive motor 112 outputs rotational power to drive the second lead screw 115 to rotate. The second lead screw nut 114 drives the cutter head bracket 104 to move along the length of the main frame 101, thereby driving the cutter head 105 to complete the surface repair of the roller.

[0048] In addition to this embodiment, the sliding drive device can also use an electric push rod. The fixed end of the electric push rod is fixedly installed on the sliding bracket 102, and the telescopic end is fixedly connected to the cutter head bracket 104. The movement of the cutter head bracket 104 is realized by controlling the extension and retraction of the telescopic end of the electric push rod.

[0049] like Figure 3As shown, the auxiliary unit 2 includes a base frame 201. Several height-adjustable support seats 202 are provided at the bottom of the base frame 201 near the edge to adjust the height of the entire auxiliary unit 2 and ensure that it is compatible with the height of the transmission components of the detection line.

[0050] An upper bracket 203 is fixedly installed above the base frame 201. The upper bracket 203 is a double-layer rectangular frame structure made of spliced ​​profiles. A drive motor 204 is fixedly installed on the lower layer of the upper bracket 203. A drive shaft 205 is rotatably installed on the upper layer of the upper bracket 203 through a bearing seat. A transmission device 206 is provided on one end of the drive shaft 205 corresponding to the drive motor 204. The other end of the transmission device 206 is fixedly connected to the drive motor 204.

[0051] In this embodiment, the transmission device 206 includes a drive sprocket fixedly installed at the power output end of the drive motor 204 and a driven sprocket fixedly installed at one end of the drive shaft 205. The drive sprocket and the driven sprocket are connected by a chain drive. In addition to this embodiment, the transmission device 206 can also be a gear set or a combination of belt and pulley to transmit the rotational power output by the drive motor 204 to the drive shaft 205.

[0052] A set of drive wheels 209 is fixedly installed on the drive shaft 205 at a position outside the transmission device 206. The set of drive wheels 209 is used to connect with the transmission components of the roller on the detection line and drive the roller to rotate using the power of the drive motor 204.

[0053] In this embodiment, the drive wheel assembly 209 includes a double row of sprockets and synchronous pulleys installed sequentially along the drive shaft 205. Depending on the type of roller drive component on the detection line, a suitable pulley or sprocket is selected for connection. The chain or belt of the detection line itself can be used directly without the need for additional purchase and installation, which improves the versatility and work efficiency of the equipment.

[0054] A tensioning wheel 207 is also provided on the upper bracket 203 at a position corresponding to the drive wheel set 209, which is used to tension the chain or belt connecting the drive wheel set 209 and the roller to prevent the belt or chain from loosening and slipping, thus affecting the power transmission efficiency.

[0055] The auxiliary assembly 2 also includes a control device 208, which is fixedly mounted on the upper bracket 203. The control device 208 is electrically connected to the drive motor 204 and controls the speed and direction of the drive motor 204. In conjunction with the movement of the cutter head 105 in the main assembly 1, the surface repair of the roller is completed.

[0056] In this embodiment, the control device 208 is a PLC. Through the built-in program, it controls the operation of the drive motor 204 to control the rotation direction and speed of the roller. This allows the equipment to accurately control the roller state and the action of the cutter head 105 during use, thereby improving the quality of roller surface repair.

[0057] The method of using the special mobile embossing drive for the dynamometer roller of a motor vehicle inspection line described in this application is as follows:

[0058] S1. Move the auxiliary machine component 2 to the roller drive component, disconnect the original drive component of the roller, and connect the drive chain or drive belt to the drive wheel set 209.

[0059] S2. Adjust the height of the drive shaft 205 by adjusting the support 202, and then adjust the tension wheel 207 to tension the transmission chain or transmission belt.

[0060] S3. Place the main unit 1 above the rollers on the detection line and adjust the sliding bracket 102 to align with one of the rollers;

[0061] S4. Change the cutter head type 105 according to the condition of the roller surface;

[0062] S5. Move the cutter head 105 to one end using the sliding drive device, and adjust the third slider 109 up and down to make the cutter head 105 contact the surface of the drum. At this time, the position of the cutter head 105 can also be finely adjusted using the fourth slider 118.

[0063] S6. Start the drive motor 204 to make the drum rotate, and at the same time start the sliding drive motor 112 to make the cutter head 105 move along the drum axis to complete the surface repair.

[0064] S7. The cutter head 105 returns to its original position. Move the sliding bracket 102 so that the cutter head 105 is aligned with the second roller. Repeat the operations of S4-S6 to complete the surface repair of the second roller.

[0065] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
