Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing and assembly tooling, specifically to a tooling fixture for positioning and assembling right-angle curved rails. Background Technology

[0002] In overhead conveyor lines, trolleys are often needed to move to different workstations to meet production requirements. Therefore, the conveyor line contains many right-angle curved rails used to change the route of the trolleys. Right-angle curved rails have many components and are relatively complicated to assemble. The traditional method is manual assembly, which requires training for assemblers and consumes a lot of time. Moreover, manual positioning and installation is time-consuming and the accuracy cannot be guaranteed. The structure of right-angle curved rails has certain special characteristics. The assembly at the corners requires ensuring the angular accuracy, spacing accuracy, and connection strength between the components. Therefore, the requirements for positioning and clamping during the assembly process are high. How to efficiently and accurately complete the assembly of right-angle curved rails has become an urgent problem to be solved. Utility Model Content

[0003] Purpose of the utility model: To overcome the above shortcomings, the purpose of this utility model is to provide a tooling fixture for positioning and assembling right-angle curved rails. By setting movable first and second limiting clamping components, precise positioning and clamping of the wide frame and lower rail are achieved. The upper and lower rail limiting blocks ensure a stable connection between the upper aluminum profile curved rail and the wide frame. In conjunction with the rail pre-positioning mechanism and the dual-axis dual-rod cylinder, the various components of the right-angle curved rail can be quickly positioned and accurately assembled, reducing manual training time, improving assembly efficiency and accuracy, and solving the problems of inaccurate positioning and low efficiency in traditional manual assembly.

[0004] Technical Solution: This utility model provides a tooling fixture for positioning and assembling right-angle curved rails, including a frame, the frame being right-angled, with a first tooling plate and a second tooling plate respectively provided on the two right-angled sides of the frame. The right-angle curved rail includes four broad frames, an upper aluminum profile curved rail, and a lower rail. The upper aluminum profile curved rail and the lower rail are correspondingly arranged and framed within the broad frames. A first limiting clamping component and a second limiting clamping component are provided, which are movably connected to the first tooling plate and the second tooling plate respectively, and are used to limit and clamp the broad frames and the lower rail. Upper and lower rail limiting blocks are provided, which are located between the upper aluminum profile curved rail and the lower rail. The upper and lower end faces of the upper and lower rail limiting blocks respectively abut against the upper aluminum profile curved rail and the lower rail. When the upper and lower rail limiting blocks move to below the broad frames, the upper aluminum profile curved rail is clamped and limited between the upper end face of the broad frame and the upper and lower rail limiting blocks. At this time, the upper aluminum profile curved rail is connected to the broad frames by bolts. The frame is right-angled, providing a basic right-angle positioning reference for the assembly of the right-angle curved rail. The first and second tooling plates are respectively set on the two right-angled sides of the frame. The first and second limiting clamping components are movably connected to these two tooling plates, facilitating fine-tuning of the position. This allows for precise positioning and stable clamping of the upper aluminum profile curved rail and the lower rail, ensuring that the upper and lower rails do not shift during assembly. Upper and lower rail limiting blocks are positioned between the upper aluminum profile curved rail and the lower rail, with their upper and lower end faces abutting against the upper aluminum profile curved rail and the lower rail, respectively. When the upper and lower rail limiting blocks move below the upper frame, the upper aluminum profile curved rail is clamped and limited between the upper frame and the upper end face of the upper and lower rail limiting blocks, providing precise positioning for the connection between the upper aluminum profile curved rail and the upper frame, ensuring the accurate relative position of the upper aluminum profile curved rail and the upper frame.

[0005] Furthermore, in this application, a tooling fixture for positioning and assembling right-angle curved rails includes a pair of first slide rails on the first tooling plate, a first slider on the first slide rail, a pair of first limiting clamping mechanisms including a first limiting clamping base plate, the first limiting clamping base plate being slidably connected to the first slide rails via the first slider, a pair of first wide frame limiting blocks and a pair of first rotary pressing angle cylinders on the first limiting clamping base plate, the wide frame being clamped between the pair of first wide frame limiting blocks, the lower rail including a lower inner rail and a lower outer rail, the pair of first rotary pressing angle cylinders being correspondingly located outside the lower inner rail and lower outer rail, limiting the lower inner rail and lower outer rail in the vertical direction, the lower inner rail and lower outer rail being connected to the wide frame by bolts, the upper and lower rail limiting blocks moving to the wide frame, their corresponding upper end faces abutting against the upper aluminum profile curved rail, at which time the upper aluminum profile curved rail is connected to the wide frame by bolts. A pair of first slide rails on the first tooling plate cooperate with the first slider, allowing the first clamping base plate to slide along the slide rails, facilitating the adjustment of the position of the first clamping mechanism according to the specifications of the wide frame. A pair of first wide frame limiting blocks can precisely clamp the wide frame, ensuring the lateral stability of the wide frame during assembly. After the upper aluminum profile curved rail and the lower rail are subdivided, a pair of first rotary clamping corner cylinders correspond to the outer sides of the lower inner rail and the lower outer rail, limiting them in the vertical direction to prevent the lower rail from shifting up and down during bolt connection. This design allows the lower inner rail and the lower outer rail to be precisely aligned with the wide frame, ensuring the accuracy of bolt connection. When the upper and lower rail limiting blocks move to the wide frame, the upper end face precisely abuts against the upper aluminum profile curved rail. Combined with the fixing of the wide frame, this forms a double limitation on the upper aluminum profile curved rail in both longitudinal and vertical directions, ensuring the precise connection position between the upper aluminum profile curved rail and the wide frame.

[0006] Furthermore, in this application, a tooling fixture for positioning and assembling right-angle curved rails includes a pair of second slide rails on the second tooling plate, with second sliders on the second slide rails. The second limiting clamping assembly includes a pair of second limiting clamping mechanisms, each including a second limiting clamping base plate. The second limiting clamping base plate is slidably connected to the second slide rails via the second sliders. The second limiting clamping base plate includes a pair of second wide-frame limiting blocks and a pair of second rotary clamping angle cylinders. The wide frame is clamped between the pair of second wide-frame limiting blocks. The pair of second rotary clamping angle cylinders are correspondingly located on the outer sides of the lower inner rail and lower outer rail, respectively, limiting the lower inner rail and lower outer rail in the vertical direction. The pair of second slide rails on the second tooling plate cooperate with the second sliders, allowing the second limiting clamping base plate to slide along the slide rails, and the position of the second limiting clamping mechanism can be flexibly adjusted according to the specifications of the wide frame. A pair of second wide-frame limiting blocks clamp the wide frame, forming a right-angled cooperative positioning with the first wide-frame limiting block on the first tooling plate. This firmly fixes the wide frame from two vertical directions, preventing it from shifting in the plane during assembly. A pair of second rotary clamping angle cylinders are correspondingly located on the outer sides of the lower inner and outer rails, limiting their vertical movement. Combined with the limiting effect of the first rotary clamping angle cylinders on the first tooling plate, this forms a bidirectional vertical limitation on the lower rail from two right-angled directions, further enhancing the stability of the lower rail during assembly and preventing it from wobbling or shifting in the vertical plane perpendicular to the rail's extension direction.

[0007] Furthermore, in this application, a tooling fixture for positioning and assembling right-angle curved rails includes a second limiting clamping assembly that further comprises a rail pre-positioning mechanism. The pre-positioning mechanism includes a third limiting base plate with a pair of rail pre-positioning blocks. The lower inner rail and lower outer rail are respectively placed on the rail pre-positioning blocks. A third slider is also provided on the second slide rail. The third limiting base plate is movably connected to the second tooling plate via the third slider. The third limiting base plate is located at the bend of the lower rail. The third limiting base plate of the rail pre-positioning mechanism is slidably connected to the second slide rail via the third slider and is located at the bend of the lower rail. The pair of rail pre-positioning blocks on the third limiting base plate can respectively support the lower inner rail and lower outer rail, providing initial support and positioning reference for the lower inner rail and lower outer rail at the bend, ensuring that the relative relationship between the two at the bend position meets the assembly requirements, and avoiding initial placement deviations due to the special structure of the bend.

[0008] Furthermore, this application discloses a tooling fixture for positioning and assembling right-angle curved rails. A dual-axis, dual-rod cylinder is mounted on the first clamping base plate of the first clamping mechanism, away from the bend of the lower rail. The dual-axis, dual-rod cylinder is installed on the side of the first clamping base plate away from the bend of the lower rail, directly facing the tangential surface of the straight rail of the lower rail. A manual valve is provided on the first tooling plate. When the manual valve is pressed, the output end of the dual-axis, dual-rod cylinder pushes and calibrates the lower rail to the correct position. The output end of the dual-axis, dual-rod cylinder can accurately push the lower rail to the correct position, achieving active calibration of the lower rail and compensating for any slight positional deviations that may occur with clamping alone.

[0009] Furthermore, in this application, a tooling fixture for positioning and assembling right-angle curved rails includes slots on both the first and second wide-frame limiting blocks. The mounting edges on both sides of the wide frame are inserted into the slots of the first and second wide-frame limiting blocks, respectively, thus limiting the position of the wide frame. The design of the slots matches the structure of the mounting edges on both sides of the wide frame, effectively adapting to its shape and ensuring that the wide frame does not become loose or misaligned within the slots.

[0010] Furthermore, in this application, a tooling fixture for positioning and assembling right-angle curved rails is provided with a track spacing block in the middle of the first limiting clamp base plate and the second limiting clamp base plate. The track spacing block is engaged between the lower inner rail and the lower outer rail to limit the distance between the lower inner rail and the lower outer rail.

[0011] Furthermore, this application provides a tooling fixture for positioning and assembling right-angle curved rails, wherein the upper and lower rail limiting blocks are cylindrical and have handles on their sides. The handles on the sides of the upper and lower rail limiting blocks provide convenient gripping points for operators to move the limiting blocks. Operators can easily move the limiting blocks to the required positions, such as below the wide frame, using the handles. This allows for flexible adjustment of the limiting block's position during assembly according to the operating steps, meeting the limiting requirements when the upper aluminum profile curved rail is connected to the wide frame.

[0012] As can be seen from the above technical solution, this utility model has the following beneficial effects: 1. The tooling fixture for positioning and assembling right-angle curved rails described in this utility model, through movable first and second limiting clamping components, combined with the cooperation of slide rails and sliders, can flexibly adjust the position according to the specifications of the right-angle curved rails, achieving precise limiting and stable clamping of the wide frame and lower rail. Specifically, the slot of the limiting block can fix the mounting edge of the wide frame, the rotating clamping angle cylinder can limit the lower rail in the vertical direction, and the rail spacing block ensures the accurate spacing between the lower inner rail and the lower outer rail, effectively preventing displacement of components during assembly and ensuring assembly accuracy.

[0013] 2. The tooling fixture for positioning and assembling right-angle curved rails described in this utility model is equipped with auxiliary structures such as a rail pre-positioning mechanism, a dual-axis, dual-rod cylinder, and upper and lower rail limiting blocks. The rail pre-positioning mechanism provides initial positioning for the bend of the lower rail, the dual-axis, dual-rod cylinder can calibrate the position of the lower rail, and the upper and lower rail limiting blocks can assist in the precise connection between the upper aluminum profile curved rail and the frame. These structures work together to significantly improve the efficiency of right-angle curved rail assembly, reduce manual training time, and improve assembly quality, thus solving the problems of inaccurate positioning and low efficiency in traditional manual assembly.

Detailed Implementation

[0016] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0018] A pair of first slide rails 111 are installed on the first tooling plate 11, and two sets of two first sliders 112 are assembled on the pair of first slide rails 111. A pair of second slide rails 121 are installed on the second tooling plate 12, and two sets of two second sliders 122 and a pair of third sliders 123 are assembled on the pair of second slide rails 121.

[0019] Limit clamping components: First limiting clamping assembly 2: slidably connected to the first slide rail 111 via a first slider 112, and includes a pair of first limiting clamping mechanisms 21. Each first limiting clamping mechanism 21 includes: The first limiting base plate 211 is on which a pair of first wide frame limiting blocks 212 (with slots) and a pair of first rotating clamping angle cylinders 213 are installed.

[0020] The mounting edges on both sides of the wide frame are inserted into the slots of the first wide frame limiting block 212 for lateral limiting.

[0021] The lower rail (including the lower inner rail and the lower outer rail) is placed below the first rotary clamping angle cylinder 213, and the cylinder clamps and limits the position in the vertical direction.

[0022] The first limiting clamp base plate 211 has a track spacing block 5 in the middle, which is inserted between the lower inner rail and the lower outer rail to fix the spacing.

[0023] A dual-axis, dual-rod cylinder 214 is installed on the side of the first limiting clamp base plate 211 away from the bend, with its output end facing the cross-section of the lower rail straight rail; the first tooling plate 11 is equipped with a manual valve 113, which, when triggered, pushes the lower rail to the calibration position (the middle position of the broad frame to ensure uniform force on the lower rail).

[0024] The second limiting clamping assembly 3 is slidably connected to the second slide rail 121 via the second slider 122 and includes a pair of second limiting clamping mechanisms 31. Each second limiting clamping mechanism 31 includes: The second limiting base plate 311 is on which a pair of second wide frame limiting blocks 312 (with slots) and a pair of second rotating clamping angle cylinders 313 are installed.

[0025] The wide frame is limited by the slot of the second wide frame limiting block 312, and the lower track is vertically pressed by the second rotary pressing corner cylinder 313.

[0026] The second limiting clamp base plate 311 also has a track spacing block 5 in the middle.

[0027] Auxiliary positioning mechanism: Track pre-positioning mechanism 32: It is slidably connected to the second slide rail 121 via the third slider 123, and includes a third limiting base plate 321 and a pair of track pre-positioning blocks 322. The lower inner rail and lower outer rail at the bend of the lower rail are pre-positioned on the track pre-positioning blocks 322, which can help determine the approximate position of the bend of the rail.

[0028] Upper and lower track limiting block 4: cylindrical structure with a handle 41 on the side. When moved to the bottom of the wide frame, its upper end face abuts against the upper aluminum profile curved rail, so that it is clamped between the wide frame and the upper end face of the limiting block 4, which facilitates bolt connection.

[0029] Assembly process: Secure the four wide frames by inserting them into the slots of the first wide frame limiting block 212 and the second wide frame limiting block 312 respectively. Keep the first limiting clamping component 2 stationary and move and adjust the second limiting clamping component 3. Insert the lower rail into the four wide frames and then insert the upper aluminum profile curved rail into the four wide frames. Place the upper and lower rail limiting blocks 4 between the upper and lower rails and temporarily place the upper aluminum profile curved rail on the upper and lower rail limiting blocks 4. The lower rail is initially positioned on the rail prepositioning block 322. The second limit clamping component 3 is moved and adjusted to the installation position. The manual valve 113 is operated, and the dual-axis double-rod cylinder 214 pushes the straight section of the lower rail to the precise position. At the same time, the lower rail is also vertically pressed and limited by the first rotary pressing corner cylinder 213 and the second rotary pressing corner cylinder 313. Meanwhile, the rail spacing block 5 limits the distance between the lower inner rail and the lower outer rail. At this time, the lower inner rail and the lower outer rail are fixed to the four brackets with bolts. Adjust the position of the upper aluminum profile curved rail to correspond with the lower rail, then move the upper and lower rail limit blocks 4 to the bottom of each frame through the handle 41, and then fix the upper aluminum profile curved rail to the four frames with bolts. Finally, the installation of the upper aluminum profile curved rail, the lower rail (lower inner rail and lower outer rail), and the four wide frames was completed.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
