Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment technology, and specifically relates to a support roller device for a precision leveling machine. Background Technology

[0002] Precision leveling machines are often used to level and correct sheet metal after it has been deformed, bent or twisted. Support rollers are an important part of leveling machines, used to adjust the height of the leveling rollers, support the leveling rollers to prevent deformation and ensure leveling accuracy.

[0003] Currently, most precision leveling machines in China use screw jacks for their support rollers. These screw jacks form a square lifting platform through four support lifting points, enabling the synchronous lifting and adjustment of multiple leveling rollers. However, this method lacks flexibility and cannot achieve independent adjustment of a single leveling roller.

[0004] Therefore, we propose a support roller device for a precision leveling machine. Utility Model Content

[0005] The purpose of this invention is to provide a support roller device for a precision leveling machine to solve the aforementioned problems in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A support roller device for a precision leveling machine includes a base, with side mounting frames installed on both sides of the base. A horizontally arranged support beam is installed on both sides of the top of the base between the two ends of the side mounting frames via a lifting cylinder. The top of the base is divided into several mounting slots by a limiting component at the position between the two support beams. A set of screw wedge block lifting and adjusting mechanisms is installed in each mounting slot.

[0008] Furthermore, several sets of side-by-side support components are installed on the top of the two support beams and on the top of each set of lead screw wedge lifting and adjusting mechanisms.

[0009] Furthermore, the side mounting brackets on both sides of the base are provided with mounting holes for installing the work roller assembly at the end positions of the support beam and the lead screw wedge block lifting and adjusting mechanism.

[0010] Furthermore, a set of movable wheels is installed at each of the four corners of the bottom of the base; and a limiting plate for guiding the movement direction of the support beam is vertically installed on the inner side of the side mounting brackets on both sides of the top of the base, corresponding to the side position of the support beam end.

[0011] Furthermore, the working roll assembly includes a leveling roll, and mounting bearing seats are fitted on the roller shafts at both ends of the leveling roll; a column is vertically mounted on the bottom of the mounting bearing seat, a mounting base is slidably fitted on the middle of the column, and an end cap is fixed to the bottom end of the column after passing through the mounting hole and extending into the side mounting frame; a spring is fitted on the column between the end cap and the mounting base; the mounting base is fixedly mounted on the top of the side mounting frame by bolts.

[0012] Furthermore, the limiting component includes two side plates and several partition plates, with the partition plates arranged at equal intervals between the two side plates.

[0013] Furthermore, the lead screw wedge block lifting and adjusting mechanism includes a pad plate, which is fixed to the bottom of the mounting groove, and a mounting block mounted on one side of the base. A geared servo motor is mounted on the mounting block, and a ball screw parallel to the pad plate is mounted on the mounting block via a bearing. The other end of the ball screw is rotatably mounted on a side mounting bracket on the other side. The output end of the geared servo motor is connected to the end of the ball screw via a transmission connection.

[0014] Furthermore, the lead screw wedge lifting and adjusting mechanism also includes a lower wedge iron fitted outside the ball screw. The bottom of the lower wedge iron is slidably attached to the pad plate, and an upper wedge iron is slidably installed on the top of the lower wedge iron. An mounting plate is fixed on the top of the upper wedge iron, and several positioning pins are integrally formed on the top of the upper wedge iron from left to right. A positioning hole corresponding to the position of the positioning pin is opened in the middle of the mounting plate to cooperate with the positioning pin.

[0015] Furthermore, a proximity switch is installed on the inner side of each of the two side mounting brackets at the end position of each mounting slot.

[0016] Furthermore, lubrication grooves are provided on the contact surfaces between the lower wedge and the pad and the upper wedge, as well as on the contact surfaces between the two sides of the lower and upper wedges and the side plates and the partition groove plates, for storing lubricating grease.

[0017] Furthermore, the support assembly includes two bases and a support roller. The base includes a lower support and an upper support. The upper support is bolted to the top of the lower support. Two fixed positions are arranged side by side between the upper support and the lower support. Two adjacent support assemblies share a base, and the support rollers on the two adjacent support assemblies are installed on the two fixed positions in an alternating manner by a roller shaft integrally formed at the center of the support roller.

[0018] Furthermore, the bottom of the leveling roller in the working roller assembly rolls in a rolling engagement with the support rollers that are staggered at corresponding positions.

[0019] Beneficial effects:

[0020] This utility model changes the traditional design of lifting platforms composed of screw lifting mechanisms. Instead, it adopts several independently designed screw wedge lifting and adjusting mechanisms to independently adjust and support the leveling rollers one-to-one. This allows the leveling machine to adjust the parameters of the leveling rollers at different positions according to production needs, thereby improving the accuracy of sheet metal straightening and leveling. Moreover, each screw wedge lifting and adjusting mechanism is independently installed and operated, making subsequent maintenance and repair simpler compared to the traditional screw lifting platform design.

[0028] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0029] Example:

[0030] The screw-lifting platform design used for adjusting the lower leveling roller 601 in current precision leveling machines involves multiple leveling rollers 601 being raised and lowered synchronously during actual operation. This design lacks flexibility and cannot allow for independent adjustment of each leveling roller 601 based on the actual installation conditions, resulting in the leveling accuracy of the leveling machine consistently failing to meet expectations. Therefore, we propose a precision leveling machine support roller device that allows for independent adjustment of each leveling roller 601. The specific solution is shown below.

[0031] like Figure 1-3 As shown, this embodiment provides a support roller device for a precision leveling machine, specifically including a base 1. A side mounting bracket 2 is installed on both sides of the base 1. Simultaneously, a horizontally positioned support beam 5 is installed on both sides of the top of the base 1, between the two ends of the side mounting brackets 2, via a lifting cylinder 4. A limiting component 7 divides the top of the base 1 between the two support beams 5 into several mounting grooves 8. The limiting component 7 includes two side plates 701 and several dividing groove plates 702, with the dividing groove plates 702 arranged equidistantly between the two side plates 701. The mounting slots 8 are all the same size. Each mounting slot 8 is equipped with a set of screw wedge lifting adjustment mechanism 11. The side mounting brackets 2 on both sides of the base 1 are provided with mounting holes 9 for installing the work roller assembly 6 at the end positions of the support beam 5 and the screw wedge lifting adjustment mechanism 11. Several sets of side-by-side support components 12 are installed on the top of the two support beams 5 and the top of each set of screw wedge lifting adjustment mechanism 11 to support the work roller assembly 6, so as to facilitate the subsequent height adjustment of the corresponding work roller assembly 6.

[0032] To facilitate subsequent equipment maintenance, the lower straightening structure unit of a large leveling machine usually needs to have a displacement function. Therefore, a set of moving wheels 3 are installed at each of the four corners of the bottom of the base 1 to facilitate the positional transfer of the entire mechanism. On the inner side of the side mounting brackets 2 on both sides of the top of the base 1, corresponding to the side position of the end of the support beam 5, limit plates are vertically installed to guide the movement direction of the support beam 5. This ensures that the support beam 5 can only move up and down under the drive of the lifting cylinder 4, which can effectively improve the stability of the support component 12 located at the edge.

[0033] To ensure that the working roller assembly 6 can always effectively cooperate with the support assembly 12, such as Figure 4 As shown, the working roller assembly 6 includes a leveling roller 601, and mounting bearing seats 602 are fitted on the roller shafts at both ends of the leveling roller 601. A column 603 is vertically mounted on the bottom of the mounting bearing seat 602, and a mounting base 604 is slidably fitted on the middle of the column 603. The bottom end of the column 603 extends through the mounting hole 9 into the side mounting frame 2 and is fixed with an end cap. A spring 605 is fitted on the column 603 between the end cap and the mounting base 604. The mounting base 604 is fixedly mounted on the top of the side mounting frame 2 by bolts. The entire working roller assembly 6 is installed on the top of the screw wedge lifting and adjusting mechanism 11 after the mounting base 604 cooperates with the mounting hole 9. With the cooperation of the spring 605, the column 603 and the end cap at the bottom end of the column 603, the leveling roller 601 always maintains a certain downward pressure, so that the leveling roller 601 can always maintain an effective rolling cooperation with the support assembly 12, thereby improving the stability of the cooperation between the working roller assembly 6 and the support assembly.

[0034] To enable independent adjustment of each pair of leveling rollers 601, such as Figure 4-6 As shown, its screw wedge lifting adjustment mechanism 11 includes a pad 111, which is fixed to the bottom of the mounting groove 8, and a mounting block 112 mounted on one side of the base 1. A geared servo motor 113 is mounted on the mounting block 112. A ball screw 114 that can rotate and is parallel to the pad 111 is mounted on the mounting block 112 via a bearing. The other end of the ball screw 114 is rotatably mounted on the side mounting bracket 2 on the other side. The output end of the geared servo motor 113 is connected to the end of the ball screw 114 for transmission, so that the geared servo motor 113 can drive the ball screw 114 to rotate.

[0035] Meanwhile, the screw wedge lifting and adjusting mechanism 11 also includes a lower wedge 115 fitted around the ball screw 114. It should be noted that the lower wedge 115 has a hole pre-drilled in the middle for the ball screw 114 to pass through, and ball screw 114 bearing seats fitted onto the ball screw 114 are fixed at both ends of this hole. The ball screw 114 bearing seats and the ball screw 114 form a screw drive structure, allowing the lower wedge 115 to move within the mounting groove 8 when the ball screw 114 rotates. The bottom of the lower wedge 115 slides against the pad 111. The top of the lower wedge 115 is slidably mounted with the upper wedge 116. The top of the upper wedge 116 is fixed with the mounting plate 117. Both ends of the mounting plate 117 and the upper wedge 116 slide against the inner surfaces of the two side mounting brackets 2. The length of the lower wedge 115 is shorter than that of the upper wedge 116, so that the lower wedge 115 has movable space in the mounting groove 8. With the continuous downward force applied by the working roller assembly 6, the lifting and lowering operation of the upper wedge 116 can be realized.

[0036] To improve the stability of the fit between the mounting plate 117 and the upper wedge 116, several positioning pins 118 are integrally formed on the top of the upper wedge 116 from left to right. The mounting plate 117 has positioning holes in the middle corresponding to the positioning pins 118. To make the relative sliding of the lower wedge 115 and the upper wedge 116 smoother, lubrication grooves are provided on the contact surfaces between the lower wedge 115 and the pad 111 and the upper wedge 116, as well as on the contact surfaces between the lower wedge 115 and the upper wedge 116 and the side plates 701 and the partition groove plate 702, for storing grease.

[0037] like Figure 4-6 As shown, a proximity switch 10 is installed on the inner side of each of the two side mounting brackets 2 at the end of each mounting slot 8. The signal output terminal of the proximity switch 10 is electrically connected to the control module of the deceleration servo motor 113 in the corresponding set of lead screw wedge lifting adjustment mechanism 11, so as to realize the feedback of the movement distance of the lower wedge 115 in the mounting slot 8, thereby achieving the purpose of precise lifting control of the support component 12.

[0038] In order to effectively lift each straightening roller, and also to ensure that each set of lead screw wedge lifting and adjusting mechanisms 11, after being installed side by side into the corresponding mounting slots 8, ... Figure 4-6As shown, the support components 12 on it can be alternately combined to fill gaps. The support components 12 include two bases and a support roller 124. The base includes a lower support 121 and an upper support 122. The upper support 122 is bolted to the top of the lower support 121. Two fixing positions 123 are arranged side by side between the upper support 122 and the lower support 121. Two adjacent support components 12 share a base, and the support rollers 124 on the two adjacent support components 12 are installed on the two fixing positions 123 in an alternating manner by a roller shaft 125 integrally formed in the center of the support roller 124. The bottom of the leveling roller 601 in the working roller assembly 6 rolls with the support rollers 124 that are staggered in the corresponding positions.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
