Description

Technical Field

[0001] This utility model relates to the field of automotive parts assembly equipment technology, and in particular to a combination tooling for improving the parallelism of product edges. Background Technology

[0002] When assembling the screen and front frame of a car's instrument panel, existing assembly equipment such as... Figure 1 As shown, it includes a screen positioning block, two front frame positioning components (one on each side), and a front frame positioning power cylinder. For the screen and front frame to be assembled, the screen size is larger than the front frame size. During installation, the screen must be placed first, followed by the front frame. This prevents the front frame from using a fixed positioning method, as this would cause screen interference during loading. Existing equipment first positions the screen using the screen positioning block, and then the operator manually places the front frame onto the front frame positioning component, using the front frame positioning power cylinder for auxiliary positioning to ensure the screen and front frame are properly aligned. However, this process relies on the accuracy and stability of manual operation. The positioning is external, requiring the positioning block to have an internal groove made according to the maximum external dimensions of the parts. When the screen's acceptable dimensions are close to the lower tolerance, a gap will appear between the screen and the positioning block, causing the screen to misalign within the positioning block. Figure 2 As shown in the diagram, the product after further assembly exhibits uneven gaps between the front frame and the screen on all four sides. Therefore, there is an urgent need for assembly tooling that can maintain good edge parallelism even when parts have manufacturing tolerances. Utility Model Content

[0003] The purpose of this invention is to provide a tooling assembly that improves the edge parallelism of a product, thereby solving the problem of poor edge parallelism when assembled with the front frame due to tolerances in the screen manufacturing process. To achieve the above objectives, this utility model provides a combined tooling for improving the parallelism of product edges, used to assemble a front frame and a screen. It includes a base plate, on which a screen positioning block is provided. A plurality of front frame positioning blocks and a floating clamping assembly are arranged around the outer periphery of the screen positioning block. The front frame positioning blocks are arranged in pairs and distributed in pairs on the same side and adjacent sides of the screen positioning blocks. The floating clamping assembly includes a floating clamping block, a screen clamping block, a movable plate, and a fixed base. The fixed base is fixed on the base plate and has a built-in cylinder. The movable plate is connected to the output end of the cylinder to move on the fixed base. The screen clamping block is fixed to the lower side of the movable plate. The floating clamping block and the movable plate are movably engaged, and a gap is left between them.

[0004] In the process of assembling the front frame and screen of an automotive instrument panel, especially when the screen size is larger than the front frame, the previously used non-adjustable equipment is replaced. Fixed front frame positioning blocks are installed on both sides of the substrate to limit the vertical and horizontal movement of the screen being cut. Floating clamping assemblies are then installed on the opposite sides of the substrate. These assemblies, driven by cylinders, clamp the screen and work in conjunction with the front frame positioning blocks to position screens with different tolerances. A movable plate, driven by cylinders, moves the screen clamping block and the floating clamping block to clamp the previously placed screen. A fixed base is used to house the various devices. The floating clamping block and the movable plate can also move relative to each other to position the front frame. When the front frame is manually installed, it is kept in contact with the front frame positioning block under the action of the floating clamping block until the front frame contacts the positioning block, thus determining the parallelism between the screen and the front frame edge.

[0005] The movable plate includes a plate body, a spring, and two guide rods. The side of the plate body near the cylinder is connected to the cylinder output end. The two ends of the spring abut against the floating clamping block and the plate body, respectively. Both guide rods pass through the plate body to connect to the floating clamping block.

[0006] After the plate is connected to the output end of the cylinder, it is displaced under the action of the cylinder output end. The two ends of the spring abut against the floating clamping block and the plate respectively. After the floating clamping block contacts the front frame, the spring is compressed to maintain the contact state with the front frame. The guide rod is used to limit the compression direction of the spring.

[0007] The plate body is provided with a first blind hole, a through hole and a mounting hole. The first blind hole abuts against one end of the spring. The through hole passes through the plate body along the displacement direction of the cylinder and is provided with a free cavity at one end near the cylinder. The mounting hole is opened at both ends of the plate body.

[0008] The first blind hole is used to house the spring, the through hole is mainly used to restrict the guide rod, and the free cavity is provided to limit the maximum distance between the plate and the front frame clamping block.

[0009] The guide rod has a limiting head at one end and a thread at the other end. The limiting head is adapted to the free cavity, and the guide rod is threadedly connected to the floating clamping block through the thread.

[0010] The guide rod is threaded so that one end of the guide rod can be fixed to the front frame clamping block. The limiting head, in conjunction with the free cavity, ensures that the end with the limiting head can only move in the direction of the cylinder, and also limits the maximum distance between the front frame clamping block and the plate.

[0011] The floating clamping block is provided with a second blind hole and a threaded hole. The second blind hole abuts against the other end of the spring, and the threaded hole is threadedly connected to the guide rod.

[0012] The second blind hole is used to house the other end of the spring. The threaded hole engages with the thread to connect the guide rod. When not subjected to external force, the spring is always in a pre-compressed state, that is, the front frame positioning block and the plate are at the maximum distance.

[0013] The fixed base is provided with two optical axis positioning rods, which pass through the fixed base along the cylinder movement direction and are placed in the mounting hole.

[0014] The two optical axis positioning rods are used to limit the movement path between the floating clamping block, the screen clamping block, the movable plate, and the fixed base.

[0015] The front frame positioning block has a protrusion, which is located on the side of the front frame positioning block near the screen positioning block. The protrusion faces the floating clamping block and is suspended above the screen positioning block.

[0016] The protrusion is suspended to restrict vertical displacement of the screen and to determine a straight line by two points, that is, by using the paired protrusions to restrict the same side of the front frame.

[0017] The substrate is also provided with a number of contact sensors, which are arranged in pairs on the outer periphery of the screen positioning block and correspond one-to-one with the front frame positioning block.

[0018] The contact sensors are configured one-to-one with the front frame positioning blocks to confirm that the screen has made contact with the protrusion under the action of the screen clamping block.

[0019] The screen positioning block is provided with a mounting groove, which is located at the edge of the screen positioning block, and a photoelectric switch is provided in the mounting groove.

[0020] The photoelectric switch is installed in the placement slot to confirm that the screen has been placed on the screen positioning block.

[0021] This utility model relates to a combination tooling for improving the parallelism of product edges. Addressing the problem in existing technologies where production tolerances cannot be addressed, resulting in poor parallelism between the screen and the front frame, the tooling structure is improved. A fixed front frame positioning block is used in conjunction with a movable floating clamping component. After the screen is fixed by the screen clamping block and the front frame positioning block, the floating clamping block performs a secondary movement when the front frame is engaged, thereby improving the edge parallelism between the front frame and the screen regardless of tolerances.

Detailed Implementation

[0035] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0036] Please see Figures 3 to 11 This utility model provides a combined tooling for improving the parallelism of product edges, used to assemble a front frame 7 and a screen 6. It includes a base plate 1, on which a screen positioning block 2 is provided. A plurality of front frame positioning blocks 3 and a floating clamping assembly 4 are arranged around the outer periphery of the screen positioning block 2. The front frame positioning blocks 3 are arranged in pairs and distributed in pairs on the same side and adjacent sides of the screen positioning blocks 2. The floating clamping assembly 4 includes a floating clamping block 11, a screen clamping block 12, a movable plate 13, and a fixed base 14. The fixed base 14 is fixed on the base plate 1 and has a built-in cylinder 5. The movable plate 13 is connected to the output end of the cylinder 5 to move on the fixed base 14. The screen clamping block 12 is fixed to the lower side of the movable plate 13. The floating clamping block 11 is movably engaged with the movable plate 13 and has a gap with the screen clamping block 12.

[0037] In this embodiment, the substrate 1 is used to house the various components. The screen positioning block 2 is mainly used to restrict the screen 6 when it is placed first. The front frame positioning block 3 mainly cooperates with the screen positioning block 2 to fix the screen 6 under the action of the screen clamping block 12. That is, screens 6 of different sizes can be fixed by the screen clamping block 12 and the screen positioning block 2. Then, the floating clamping block 11 is used to adjust the position of the subsequently placed front frame 7. Maintaining a contact state allows the front frame 7 to move on the upper side of the screen 6 until the front frame 7 contacts the front frame positioning block 3. The front frame positioning block 3 is provided with a step that matches the front frame 7, so that the front frame 7 and the screen 6 have good parallelism on the side close to the front frame positioning block 3. The gap setting ensures that the movement of the floating clamping block 11 will not be interfered with.

[0038] Furthermore, the movable plate 13 includes a plate body 111, a spring 112, and two guide rods 113. The side of the plate body 111 near the cylinder 5 is connected to the output end of the cylinder 5. The two ends of the spring 112 abut against the floating clamping block 11 and the plate body 111, respectively. Both guide rods 113 pass through the plate body 111 to connect to the floating clamping block 11.

[0039] In this embodiment, after the two ends of the spring 112 abut against each other, it is always in a pre-compressed state, so that the plate 111 and the floating clamping block 11 are always at the maximum distance. The guide rod 113 is used to limit the compression direction of the spring 112, which also limits the compression direction between the plate 111 and the floating clamping block 11.

[0040] Furthermore, the plate 111 is provided with a first blind hole 114, a through hole 115 and a mounting hole 116. The first blind hole 114 abuts against one end of the spring 112. The through hole 115 passes through the plate 111 along the displacement direction of the cylinder 5 and a free cavity 117 is provided at one end near the cylinder 5. The mounting hole 116 is opened at both ends of the plate 111.

[0041] The first blind hole 114 is used to house the spring 112, and the through hole 115 cooperates with the free cavity 117 to restrict the movement path of the guide rod 113.

[0042] Furthermore, one end of the guide rod 113 is provided with a limiting head 118, and the other end is provided with a thread 119. The limiting head 118 is adapted to the free cavity 117, and the guide rod 113 is threadedly connected to the floating clamping block 11 through the thread 119.

[0043] The limiting head 118 is configured such that the guide rod 113 is limited when it enters the free cavity 117, thereby limiting the maximum distance between the plate 111 and the floating clamping block 11. The thread 119 is used to fix the guide rod 113 in the floating clamping block 11. When the floating clamping block 11 is displaced by an external force, the guide rod 113 can disengage from the free cavity 117, thereby reducing the distance between the floating clamping block 11 and the plate 111. This process occurs after the front frame 7 is installed, during the secondary positioning process of the floating clamping block 11.

[0044] Furthermore, the floating clamping block 11 is provided with a second blind hole 120 and a threaded hole 121. The second blind hole 120 abuts against the other end of the spring 112, and the threaded hole 121 is threadedly connected to the guide rod 113.

[0045] The second blind hole 120 is used to cooperate with the spring 112, and the threaded hole 121 cooperates with the thread 119 to fix one end of the guide rod 113.

[0046] Furthermore, the fixed base 14 is provided with two optical axis positioning rods 122, which pass through the fixed base 14 along the movement direction of the cylinder 5 and are placed in the mounting hole 116.

[0047] The optical axis positioning rod 122 is used to limit the displacement path between the plate 111 and the fixed seat 14, so as to avoid misalignment between the plate 111 and the fixed seat 14.

[0048] Furthermore, the front frame positioning block 3 has a protrusion 123, which is disposed on the side of the front frame positioning block 3 near the screen positioning block 2. The protrusion 123 faces the floating clamping block 11 and is suspended above the screen positioning block 2.

[0049] The protrusion 123 is suspended to restrict the vertical displacement of the screen 6 on the one hand, and to determine the straight line by two points, that is, to restrict the same side of the front frame 7 by the pair of protrusions 123.

[0050] Furthermore, the substrate 1 is also provided with a plurality of contact sensors 124, which are arranged in pairs on the outer periphery of the screen positioning block 2 and correspond one-to-one with the front frame positioning block 3.

[0051] The contact sensor 124 is configured one-to-one with the front frame positioning block 3 to confirm that the screen 6 has made contact with the protrusion 123 under the action of the screen clamping block 12.

[0052] Furthermore, the screen positioning block 2 is provided with a mounting groove 125, which is located at the edge of the screen positioning block 2, and a photoelectric switch 126 is provided in the mounting groove 125.

[0053] The photoelectric switch is installed in the placement slot 125 to confirm that the screen 6 has been placed on the screen positioning block 2.

[0054] The specific implementation process for this combination is as follows: First, the screen 6 is placed on the screen positioning block 2. The cylinder 5 is used to push the screen 6 until it is fixed between the protrusion 123 and the screen positioning block 2. At this point, the screen 6 is fixed regardless of tolerances. Then, the front frame 7 is installed. One side of the front frame 7 is placed above the side that abuts the front frame positioning block 3. The other side of the front frame 7 is placed on the screen 6 by flipping and snapping. The floating clamping block 11 maintains the drive of the front frame 7 under the action of the spring 112, so that the front frame 7 can contact the front frame positioning block 3 under the action of the floating clamping block 11. Based on the principle of two points determining a straight line, the positions of the front frame 7 and the screen 6 are limited respectively, and the edges of the front frame 7 and the screen 6 have good parallelism, thereby improving the parallelism. The floating clamping block 11 can compress the spring 112, so that the front frame 7 always maintains contact with the floating clamping block 11 to ensure good parallelism.

[0055] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
