Description

Technical Field

[0001] This utility model relates to the field of rubber processing technology, and in particular to a special fixture for drilling holes in a rear-inflating tray. Background Technology

[0002] The inflatable tray after the vulcanization process is made by cutting iron plates, and the surface of the inflatable tray needs to be perforated.

[0003] However, when the inventors implemented this device, they found the following defects: In the traditional scribing and drilling processing mode, manual scribing requires operators to use tools such as steel rulers and scribing needles to mark the parts of the workpiece to be processed one by one. In the process, not only must the dimensions be repeatedly measured and checked, but the scribing position must also be frequently changed. After scribing is completed, the operator must move the workpiece to the drilling equipment again and manually adjust the drill bit position according to the scribing marks. The tool setting and calibration operations before each drilling will consume a lot of time, resulting in extremely low overall processing efficiency. Summary of the Invention

[0004] Based on this, it is necessary to address the aforementioned technical problems. In the traditional scribing and drilling processing mode, manual scribing requires operators to use tools such as steel rulers and scribing needles to mark the parts of the workpiece to be processed one by one. During the process, not only are the dimensions repeatedly measured and checked, but the scribing position also needs to be frequently changed. After scribing is completed, the operator needs to move the workpiece to the drilling equipment again and manually adjust the drill bit position according to the scribing marks. The tool setting and calibration operations before each drilling consume a lot of time, resulting in extremely low overall processing efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a special fixture for drilling holes in a rear-inflatable tray, comprising a fixture body, the fixture body comprising an upper plate and a lower plate, the lower plate being located below the upper plate, protruding plates being fixedly installed on the sides of both the lower plate and the upper plate, a connecting mechanism being provided inside the protruding plate, a positioning ring being provided on the side of the protruding plate, the positioning ring being fixedly connected to the protruding plate through the connecting mechanism, and a cable being connected between the two positioning rings.

[0006] In a preferred embodiment of the special fixture for drilling holes in a rear-inflatable tray provided by this utility model, a fixing nail is provided on the top of the lower plate, and the fixing nail is located in the middle of the lower plate.

[0007] In a preferred embodiment of the special fixture for drilling holes in a rear-inflatable tray provided by this utility model, the surface of the fixing nail is provided with threads.

[0008] As a preferred embodiment of the special fixture for drilling holes in a rear-inflating tray provided by this utility model, the surface of the upper plate is provided with a plurality of positioning holes, which are evenly distributed.

[0009] In a preferred embodiment of the special fixture for drilling holes in a rear-inflatable tray provided by this utility model, a plug-in post is fixedly installed at the end of the positioning ring, and a plug-in hole is provided at the end of the protruding plate.

[0010] As a preferred embodiment of the special fixture for drilling holes in a rear-inflatable tray provided by this utility model, the end of the insertion post has two symmetrical slots. The connecting mechanism includes two L-shaped hooks, which are symmetrically arranged on both sides of the insertion post. Each of the two L-shaped hooks has a rotating shaft at its middle end, and the rotating shaft is connected to the inner wall of the protruding plate. One end of the L-shaped hook near the insertion post is inserted into the slot, and the other end of the L-shaped hook is connected to a spring. The other end of the spring is connected to the middle of the protruding plate.

[0011] As a preferred embodiment of the special fixture for drilling holes in a rear-inflatable tray provided by this utility model, compression blocks are movably installed on both sides of the protruding plate, and the compression blocks correspond to the end of the L-shaped hook block away from the insertion post.

[0012] As a preferred embodiment of the special fixture for drilling holes in a rear-inflatable tray provided by this utility model, the end of the L-shaped hook block is provided with an arc-shaped surface, and the end of the insertion post is provided with an arc-shaped angle.

[0013] As a preferred embodiment of the special fixture for drilling holes in a rear-inflatable tray provided by this utility model, the middle surface of the insertion post is provided with a threaded surface, and the surface of the insertion hole is provided with a threaded groove corresponding to the threaded surface.

[0014] In a preferred embodiment of the special fixture for drilling holes in a rear-inflated tray provided by this utility model, the cable is made of metal.

[0015] Compared with existing technologies, this utility model has the following advantages: The fixing pin in the middle of the lower plate is inserted into the center hole at the bottom of the tray, directly defining the center position of the tray and avoiding hole offset caused by manual alignment errors. This is especially suitable for scenarios requiring high concentricity and symmetry of the holes. The threaded design on the surface of the fixing pin prevents the tray from sliding when installing the upper plate or adjusting the positioning ring, further improving positioning stability. Multiple evenly distributed positioning holes on the surface of the upper plate are aligned with the drill bit axis of the drilling equipment, serving as a guide reference for the drilling path and ensuring hole accuracy. The hole spacing and angle deviation can be controlled within millimeter-level precision, meeting the processing requirements of high-consistency products. The cable connects the upper and lower plates, forming a flexible connection structure, ensuring that the upper and lower plates are not lost. The threaded surface in the middle of the insertion post cooperates with the threaded groove of the insertion hole. By rotating the positioning ring, the insertion post can be screwed deep into the hole. Combined with the mechanical locking structure, this ensures a firm connection of the positioning ring, preventing loosening during processing, and also simplifies cable replacement.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0023] As described in the background art, in the traditional scribing and drilling processing mode, manual scribing requires operators to use tools such as steel rulers and scribing needles to mark the parts of the workpiece to be processed one by one. In the process, not only must the dimensions be repeatedly measured and checked, but the scribing position must also be frequently changed. After scribing is completed, the operator must move the workpiece to the drilling equipment again and manually adjust the drill bit position according to the scribing marks. The tool setting and calibration operations before each drilling consume a lot of time, resulting in extremely low overall processing efficiency.

[0024] To solve this technical problem, this utility model provides a special fixture for drilling holes in a rear-inflatable tray, which includes a fixture body 14. The fixture body 14 includes an upper plate 2 and a lower plate 1. The lower plate 1 is located below the upper plate 2. A protruding plate 3 is fixedly installed on the side of both the lower plate 1 and the upper plate 2. A connecting mechanism is provided inside the protruding plate 3. A positioning ring 4 is provided on the side of the protruding plate 3. The positioning ring 4 is fixedly connected to the protruding plate 3 through the connecting mechanism. A cable 5 is connected between the two positioning rings 4.

[0025] By setting up the upper plate 2 and the lower plate 1, the processing error can be effectively overcome, ensuring the dimensional and shape accuracy of the workpiece, improving work efficiency and reducing labor intensity. The cable 5 can connect the upper plate 2 and the lower plate 1 to form a flexible connection structure, ensuring that the upper plate 2 and the lower plate 1 will not be lost. The threaded surface 8 in the middle of the plug-in post cooperates with the threaded groove of the plug-in hole. By rotating the positioning ring, the plug-in post can be screwed into the hole. Combined with the mechanical locking structure, it ensures that the positioning ring is firmly connected and avoids loosening during processing. Example 1

[0026] Please refer to Figure 1-4 The bottom plate 1 is provided with a fixing nail 12 at the top and the fixing nail 12 is located in the middle of the bottom plate 1. When the rear inflatable tray is placed on the bottom plate 1, the center hole at the bottom of the tray is aligned with the fixing nail 12. The fixing nail 12 is inserted into the hole to achieve the center positioning of the tray in the horizontal plane, ensuring the relative position accuracy of the tray and the fixture body 14. The fixing nail 12 directly defines the center position of the tray, avoiding hole offset caused by manual alignment error. It is especially suitable for processing scenarios with high requirements for hole concentricity and symmetry.

[0027] The surface of the fixing nail 12 is threaded to prevent the tray from sliding during subsequent installation of the upper plate 2 or adjustment of the positioning ring 4.

[0028] The surface of the upper plate 2 has multiple positioning holes 13, which are evenly distributed. The positioning holes 13 are aligned with the axis of the drill bit of the drilling equipment and serve as a guide reference for the drilling path. When the tray is fixed between the upper plate 2 and the lower plate 1, the drill bit directly processes the corresponding position of the tray through the positioning holes 13 to ensure the accuracy of the hole position. The even distribution of the positioning holes 13 provides a precise coordinate reference for the hole position of the tray, ensuring that the hole spacing and angle deviation are controlled within the millimeter accuracy range, which is especially suitable for products with high requirements for hole position consistency. Example 2

[0029] Further optimizations to Example 1, specifically, such as... Figure 1-4 As shown: The end of the positioning ring 4 is fixedly installed with a plug post 7, and the end of the protruding plate 3 is provided with a plug hole; the positioning ring 4 is aligned with the plug post 7 at its end and inserted into the plug hole of the protruding plate 3 along the axial direction to achieve initial fixation.

[0030] Two slots 9 are symmetrically provided at the end of the insertion post 7. The connecting mechanism includes two L-shaped hook blocks 10, which are symmetrically arranged on both sides of the insertion post 7. A pivot is provided at the middle of each L-shaped hook block 10, and the pivot is connected to the inner wall of the protruding plate 3. One end of the L-shaped hook block 10 near the insertion post 7 is inserted into the slot 9, and the other end of the L-shaped hook block 10 is connected to a spring 11. The other end of the spring 11 is connected to the middle of the protruding plate 3. Align the insertion post 7 of the positioning ring 4 with the protruding plate 3. When the insertion hole of the plate 3 is pushed in axially, the slot 9 at the end of the insertion post 7 moves with the post. During the insertion process of the insertion post 7, the end of the insertion post 7 has a squeezing effect on the L-shaped hook block 10, which overcomes the elastic force of the spring 11 and makes the L-shaped hook block 10 rotate away from the insertion post 7 around the axis of rotation. When the insertion post 7 is fully inserted into the protruding plate 3, the thrust of the spring 11 drives the L-shaped hook block 10 to rotate around the axis of rotation, so that the front end of the hook block is inserted into the slot 9, forming a mechanical lock.

[0031] The two sides of the protruding plate 3 are movably mounted with pressing blocks 6, which correspond to the end of the L-shaped hook block 10 away from the insertion post 7. The pressing blocks 6 correspond to the non-insertion end of the L-shaped hook block 10. When it is necessary to disassemble or adjust the positioning ring 4, the pressing blocks 6 on both sides are manually pressed. The pressing blocks 6 move inward and push the tail of the L-shaped hook block 10. Since the L-shaped hook block 10 is hinged to the inner wall of the protruding plate 3 through a rotating shaft, the tail will rotate around the rotating shaft after being subjected to force, causing the head to disengage from the slot 9 of the insertion post 7. At this time, the spring 11 is compressed, and the insertion post 7 loses the locking of the L-shaped hook block 10. No tools are needed, which greatly simplifies the disassembly and assembly process of the positioning ring 4, shortens the equipment adjustment time, and is suitable for processing scenarios where the positioning position is frequently changed or adjusted. Example 3

[0032] Further optimizations to Example 2, such as Figure 1-4 As shown: The end of the L-shaped hook block 10 is provided with an arc-shaped surface, and the end of the insertion post 7 is provided with an arc-shaped corner. When the insertion post 7 is inserted into the insertion hole of the protruding plate 3, the arc-shaped corner at the end of the insertion post 7 first contacts the arc-shaped surface of the L-shaped hook block 10. As the insertion post 7 goes deeper, the arc-shaped corner slides along the arc-shaped surface, using the inclined plane thrust to push the L-shaped hook block 10 outward until the slot 9 is aligned with the head of the L-shaped hook block 10. When the slot 9 reaches the locking position, the spring 11 resets, pushing the head of the L-shaped hook block 10 into the slot 9, completing the automatic locking. The sliding cooperation of the arc-shaped surface and the arc-shaped corner makes the insertion process unnecessary for manual alignment assistance. The locking mechanism can be triggered simply by the insertion action of the insertion post 7.

[0033] The middle surface of the plug pin 7 is provided with a threaded surface 8, and the surface of the plug hole is provided with a threaded groove corresponding to the threaded surface 8. By aligning the plug pin 7 of the positioning ring 4 with the plug hole of the protruding plate 3 and rotating the positioning ring 4, the plug pin 7 can be gradually screwed into the depth of the plug hole.

[0034] Cable 5 is made of metal; cable 5 is used to connect the lower plate 1 and the upper plate 2, restricting their relative displacement, and cable 5 has extremely high tensile strength and durability.

[0035] The process of using the special fixture for drilling holes in a rear-inflatable tray provided by this utility model is as follows: First, pick up the positioning ring 4 and align the insertion post 7 at its end with the insertion hole of the protruding plate 3. Insert the positioning ring 4 axially until the threaded surface 8 initially engages with the thread groove. Rotate the positioning ring 4 to gradually screw the insertion post 7 deep into the insertion hole. The arc-shaped angle at the end of the insertion post 7 contacts the arc-shaped surface of the L-shaped hook block 10. The inclined thrust forces the L-shaped hook block 10 to rotate around the axis, compressing the spring 11 and... Move outwards until the insertion post 7 is fully inserted into the insertion hole, and the slot 9 moves below the head of the L-shaped hook block 10. Then, the spring 11 resets, driving the hook block head to engage with the slot 9, forming a mechanical lock. Next, ensure the lower plate 1 is placed horizontally, and the upper plate 2 is initially aligned with the lower plate 1 via the protruding plate 3. The positioning ring 4 is fixed to the side of the protruding plate 3 via a connecting mechanism. Then, remove the rear inflation tray, align the center hole at its bottom with the fixing pin 12 in the middle of the lower plate 1, and gently press the tray vertically downwards to screw the threaded portion of the fixing pin 12 in. The pallet holes ensure center positioning in the horizontal plane, while the threaded structure prevents the pallet from sliding. The upper plate 2 covers the pallet, aligning the protruding plate 3 of the upper plate 2 with the protruding plate 3 of the lower plate 1. At this point, the positioning holes 13 on the surface of the upper plate 2 must correspond to the drilling positions on the pallet, serving as a guide reference for subsequent drilling. The cable 5 connects the lower plate 1 and the upper plate 2, limiting their relative displacement. Due to the different pallet heights, the length of the cable 5 needs to be adjusted. The pressing block 6 corresponds to the non-insertion end of the L-shaped hook block 10. When it is necessary to disassemble or adjust the positioning ring 4, manually press the pressing blocks 6 on both sides. The pressing blocks 6 move inward and push the tail of the L-shaped hook block 10. Since the L-shaped hook block 10 is hinged to the inner wall of the protruding plate 3 through the rotating shaft, the tail will rotate around the rotating shaft after being subjected to force, causing the head to disengage from the slot 9 of the plug post 7. At this time, the spring 11 is compressed, and the plug post 7 loses the locking of the L-shaped hook block 10. No tools are needed, which greatly simplifies the disassembly and assembly process of the positioning ring 4, shortens the equipment adjustment time, and is suitable for processing scenarios where the positioning position is frequently changed or adjusted.
