Description

Technical Field

[0001] This application relates to the field of track assembly technology, and more specifically, to a positioning mechanism for assembly. Background Technology

[0002] Traditional floor-rail type large-format laser cutting machines use a segmented, spliced ​​guide rail bed (floor rail) to provide basic support for the moving parts of the laser cutting machine. The floor rail is usually composed of multiple sections of the guide rail bed (for example, a 26-meter-long machine is composed of multiple spliced ​​sections), which need to be assembled on site. The sections of the floor rail are connected by bolts or welding, and the straightness and levelness of the joints must be ensured during splicing.

[0003] Currently, multi-section guide rails are mostly assembled manually on the ground on-site. This assembly method has limitations in practical operation, as follows:

[0004] First, the splicing of the ground rail bed is time-consuming and labor-intensive, especially since the straightness of the interface needs to be ensured during splicing. However, ground settlement or improper installation can lead to cumulative errors, making accurate positioning impossible.

[0005] Secondly, while ensuring straightness, most current methods rely on optical collimators for testing. However, this traditional method results in a large straightness error (e.g., a 26-meter guide rail can only achieve about 6mm of straightness because the steel rail expands by 0.012mm / m for every 1℃ change in temperature. The theoretical expansion of a 26-meter guide rail with a daytime temperature difference of 10℃ is 3.12mm, but in reality, due to the non-uniformity of the material, local buckling deformation is amplified to 5-8mm). At the same time, the product is affected by the environment (temperature, humidity) and ground deformation, and the interface is prone to further deformation or positional displacement. Therefore, frequent maintenance and correction are required, increasing the difficulty and cost of after-sales maintenance. Utility Model Content

[0006] The technical problem to be solved by the embodiments of this application is how to quickly and accurately position the product during splicing and how to make subsequent maintenance easy.

[0007] To address the aforementioned technical problems, this application provides an assembly positioning mechanism, employing the following technical solution:

[0008] An assembly positioning mechanism is used to position multiple products arranged in a straight line. The positioning mechanism includes: a bottom pad, locking members, and a straightening member; the bottom pad has a front and a back, the back is configured to be positioned and connected to the ground, and the front is configured to support the splicing ends of two adjacent products; multiple locking members are symmetrically arranged on both sides of the front for clamping the two products to be spliced; a straightening member is provided on one side of each locking member, and the straightening member has an actuating part that pushes the locking member to move linearly so that the splicing end faces of the two products to be spliced ​​coincide.

[0009] Furthermore, the calibration component includes a fixing plate, which is positioned and connected to the front side. The surface of the fixing plate is provided with a movable hole, the axis of which is perpendicular to the surface along the length direction of the product. The actuator is movably disposed in the movable hole and moves along the axis of the movable hole. The end of the actuator facing the product is positioned and connected to the locking component.

[0010] Furthermore, the actuator is a screw.

[0011] Furthermore, the locking element includes a slider that is slidably disposed on the front side of the bottom pad.

[0012] Furthermore, the slider has a bent portion at the end away from the product, the bent portion protruding towards the product and forming a set angle with the slider, and a pressing portion at the end of the bent portion facing the product, the pressing portion being configured to limit the product on the upper surface of the slider; a clamping member is provided on the pressing portion, the clamping member being configured to position and connect the product to the slider; the end of the actuator facing the product passes through the bent portion, and the actuator is configured to drive the bent portion to move along the axial direction of the actuator.

[0013] Furthermore, the end of the pressing part facing the product is provided with a positioning groove, which is configured to limit the position of the product's feet.

[0014] Furthermore, the locking component also includes a guide hole disposed on the upper surface of the slider, and the front side is provided with a locking hole that matches the guide hole.

[0015] Furthermore, at least two guide holes are provided.

[0016] Furthermore, there are four locking components, which are arranged symmetrically in pairs.

[0037] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0038] like Figures 1-13 As shown, this application provides a positioning mechanism for assembly.

[0039] Specifically, the assembly positioning mechanism is used to position multiple products A arranged in a straight line. The positioning mechanism includes: a bottom pad 1, locking members 2, and a correcting member 3. The bottom pad 1 has a front side 4 and a back side. The back side is configured to be connected to the ground for positioning, and the front side 4 is configured to support the splicing ends of two adjacent products A. Multiple locking members 2 are symmetrically arranged on both sides of the front side 4 to clamp the two products A to be spliced. Each locking member 2 has a correcting member 3 on one side. The correcting member 3 has an actuating part 5, which pushes the locking member 2 to move linearly so that the splicing end faces of the two products A to be spliced ​​coincide.

[0040] This utility model can quickly and accurately position product A through the cooperation of locking part 2 and correction part 3, so that the two products A can be quickly positioned when splicing. At the same time, the correction part 3 can ensure the splicing accuracy of the two products A. After splicing, if there is a positional deviation, it can be corrected again by correction part 3. It is highly efficient and easy to maintain.

[0041] Specifically, product A is placed directly on the front 4 of the bottom pad 1. At the same time, two locking parts 2 are fixed on each product A. Then, the locking parts 2 are driven to move along the direction parallel to the splicing surface by the actuator 5 on the correction part 3 until the end faces of two adjacent products A coincide, thus completing the precise positioning of product A.

[0042] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0043] Example 1

[0044] An assembly positioning mechanism is used to position multiple products A arranged in a straight line. The positioning mechanism includes a bottom pad 1, locking members 2, and a correcting member 3. The bottom pad 1 has a front side 4 and a back side. The back side is configured to be connected to the ground for positioning, and the front side 4 is configured to support the splicing ends of two adjacent products A. Multiple locking members 2 are symmetrically arranged on both sides of the front side 4 to clamp the two products A to be spliced. Each locking member 2 has a correcting member 3 on one side. The correcting member 3 has an actuating part 5, which pushes the locking member 2 to move linearly so that the splicing end faces of the two products A to be spliced ​​coincide.

[0045] This utility model can quickly and accurately position product A through the cooperation of locking part 2 and correction part 3, so that product A can be quickly positioned during splicing. At the same time, the correction part 3 can ensure the splicing accuracy of the two products A. After splicing, if there is a positional deviation, it can be corrected again by correction part 3. It is highly efficient and easy to maintain.

[0046] Specifically, product A is placed directly on the front 4 of the bottom pad 1. At the same time, two locking parts 2 are fixed on each product A. Then, the locking parts 2 are driven to move along the direction parallel to the splicing surface by the actuator 5 on the correction part 3 until the end faces of two adjacent products A coincide, thus completing the precise positioning of product A.

[0047] It should be noted that if there is a height difference between the two products A, the bottom pad 1 can be fixed first so that the front 4 of the adjacent bottom pad 1 is flush (for example, by pressing down or burying bolts in the ground, the bottom pad 1 is placed on the bolts, and then the front 4 of the adjacent bottom pad 1 is adjusted to be flush by rotating the nut).

[0048] After placing product A with its front surface 4 flush with the adjacent bottom pad 1, it can also be ensured that it is flush.

[0049] It should be noted that the calibration component 3 can be a linear drive device such as an electric actuator or a hydraulic actuator, while the actuator 5 can be the drive end of the linear drive device.

[0050] Meanwhile, the output end of the actuator 5 is positioned and connected to the locking member 2. This connection can be achieved by welding or by a fixing method similar to that of a screw and a sliding sleeve. In simple terms, the locking member 2 has internal threads that match the actuator 5. The actuator 5 rotates to move the locking member 2.

[0051] In some specific embodiments, the correction component 3 includes a fixing plate 6, which is positioned and connected to the front surface 4. The surface of the fixing plate 6 is provided with a movable hole 7, and the axis of the movable hole 7 is perpendicular to the surface of the product A along its length. The actuating part 5 is movably disposed in the movable hole 7 and moves along the axis of the movable hole 7. The end of the actuating part 5 facing the product A is positioned and connected to the locking component 2.

[0052] In some specific embodiments, the actuator 5 is a screw.

[0053] The actuator 5 can also be a hydraulic piston rod or an electric push rod. The hydraulic piston rod and the oil injection device are separate. However, this operation requires pressure in the pipeline connecting the hydraulic piston rod and the oil injection device. Therefore, a screw is directly selected, so as to quickly achieve accurate positioning of the two products A without occupying a large space, and with fewer limitations.

[0054] Specifically, if it is necessary to adjust the precision of product A, simply drive the screws on both sides of product A to move towards product A. Since the screws can move along the axis of the movable hole 7, the end of product A will move in a direction parallel to the axis of the movable hole 7. During this process, the precision of splicing the two products A can be further ensured by adjusting the screw pitch and using external auxiliary components or detection instruments mounted on the screws.

[0055] In some specific embodiments, the locking member 2 includes a slider 8, which is slidably disposed on the front side 4 of the bottom pad 1.

[0056] The slider 8 mainly serves to guide the sliding of product A and reduce friction during sliding. If the slider 8 is simply fixed on product A and connected to the screw (at which point product A is in direct contact with front 4), it means that product A slides on its own, which can easily lead to greater friction between product A and front 4.

[0057] Specifically, product A, i.e., the ground rail, will press on slider 8. After that, the drive screw will move towards product A. During the movement of the screw, it will drive slider 8 and ground rail to move together. However, since the ground rail is pressing on slider 8, it means that only slider 8 is rubbing against the front side 4 at this point.

[0058] It should be noted that the friction between slider 8 and front surface 4 can be sliding friction or / and rolling friction.

[0059] In some specific embodiments, the end of the slider 8 away from the product A is provided with a bent portion 10. The bent portion 10 protrudes towards the product A and forms a set angle with the slider 8. The end of the bent portion 10 is provided with a pressing portion 11 facing the product A. The pressing portion 11 is configured to limit the product A on the upper surface of the slider 8. The pressing portion 11 is provided with a clamping member 9, which is configured to position and connect the product A to the slider 8. The end of the actuator 5 facing the product A passes through the bent portion 10. The actuator 5 is configured to drive the bent portion 10 to move along the axis of the actuator 5. The connection between the actuator 5 (i.e., the actuator 5 is provided with threads) and the bent portion 10 (the bent portion 10 is provided with a hole that mates with the actuator 5) can be referred to as a lead screw and sliding sleeve mechanism. This operation can ensure the accuracy during adjustment.

[0060] The slider 8, the bending part 10, and the pressing part 11 are combined to form a U-shaped structure.

[0061] The clamping component 9 is a bolt, which, together with a nut, positions and connects product A to slider 8.

[0062] In some specific embodiments, the pressing part 11 is provided with a positioning groove 12 at one end facing the product A, and the positioning groove 12 is configured to limit the foot of the product A.

[0063] Specifically, first, the foot B of product A is inserted into the positioning groove 12. Then, it is positioned and connected to the slider 8 via the clamping member 9, as follows: Figure 2 , Figure 4 As shown.

[0064] In this way, slider 8 and product A can share the force.

[0065] Then, once the screw is turned and a certain screw is driven to move towards product A, the slider 8 corresponding to that screw will move. When sliding, the foot B will move with product A, so that the splicing surfaces of the two products A gradually overlap.

[0066] Example 2

[0067] In some specific embodiments, the locking member 2 further includes a guide hole 13 disposed on the upper surface of the slider 8, and the front side 4 is provided with a snap hole 14 that matches the guide hole 13.

[0068] With the above design, the slider 8 can be limited by the limiting posts (e.g., bolts, pillars, etc.) set in the card hole 14 and guide hole 13 when sliding, so that the sliding direction of the slider 8 is linear.

[0069] The 14 is used for fixing, and the guide hole 13 is used for positioning with the limit post.

[0070] In some specific embodiments, at least two guide holes 13 are provided.

[0071] The above settings make the slider 8 more stable when sliding.

[0072] Example 3

[0073] In some specific embodiments, four locking members 2 are provided, and the four locking members 2 are arranged symmetrically in pairs.

[0074] With the above design, when adjusting the position of product A, the position can be fixed by one of the locking parts 2 on each of the two products A to determine the error between the two products A, and then the locking part 2 on the product A with the error can be adjusted accordingly.

[0075] In some specific embodiments, the bottom pad 1 also includes fixing holes 15 provided on the front side 4.

[0076] By using screws or other components to fix the bottom pad 1 through the fixing holes 15, the position of the bottom pad 1 is determined, and the accuracy will not be affected when adjusting the ground rail.

[0077] Working principle:

[0078] First, fix the bottom pad 1 to the ground through the fixing hole 15 to prevent the calibrator 3 from shaking during adjustment.

[0079] Next, the initial position is fixed by one of the locking parts 2 on each of the two products A, that is, the ground rail foot B is connected to the locking part 2. At the same time, one locking part 2 is fixed first to determine the error between the two products A. Then, the other locking part 2 on the product A with the error is adjusted accordingly.

[0080] Specifically, first, the foot B of product A is inserted into the positioning groove 12. Then, it is positioned and connected to the slider 8 via the clamping member 9, as follows: Figure 2 , Figure 4 As shown.

[0081] In this way, slider 8 and product A can share the force.

[0082] Then, once the screw is turned and a certain screw is driven to move towards product A, the slider 8 corresponding to that screw will move. When sliding, the foot B will move with product A, so that the splicing surfaces of the two products A gradually overlap.

[0083] Obviously, the embodiments described above are only some embodiments of this application, not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application. This application can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this application.
