Description

Technical Field

[0001] This utility model relates to the field of machining and assembly technology, and in particular to a fixing fixture for bonding round strips. Background Technology

[0002] With the continuous development of industrial technology, the requirements for the quality and processing precision of circular strips are becoming increasingly stringent. High-quality circular strip processing can improve the overall performance of equipment, reduce the probability of failure, lower maintenance costs, and thus improve production efficiency and product quality. Therefore, the continuous improvement of circular strip processing technology has become an important research direction.

[0003] In existing circular strip bonding and fixing processes, to ensure the accuracy and stability of the bonding process, two specially designed clamping fixtures are usually required. First, the circular strip to be bonded and fixed is placed horizontally on a suitable work platform. The operator manipulates the clamping fixtures to insert both ends of the circular strip into the clamping parts of the fixtures. After the two clamping fixtures have firmly clamped both ends of the circular strip, the two ends of the circular strip are bonded together.

[0004] Regarding the aforementioned technologies, in actual application, this method of clamping and bonding the pipe alone is prone to problems such as the docking distance being too close or too far. If the distance is too close, the round strip will be excessively squeezed and overflow. If the distance is too far, the docking surfaces will not fit sufficiently, forming gaps or weak adhesion, resulting in bonding failure and affecting the bonding quality of the round strip. Utility Model Content

[0005] To improve the bonding quality of round strips, this application provides a fixing fixture for bonding round strips.

[0006] This application provides a fixing fixture for bonding round tapes, which adopts the following technical solution: A fixing fixture for bonding round strips includes two positioning blocks, characterized in that: both positioning blocks are provided with slots along the transverse direction, the two ends of the round strip are respectively located in the two slots, the upper end of the positioning block is provided with a positioning element, the positioning element is used to position the round strip during the processing of the round strip, a holding block is provided on one side of each positioning block, and an elastic element is fixed between the two holding blocks. In the natural state, the elastic element drives the two positioning blocks to move closer to each other.

[0007] By adopting the above technical solution, during the processing of round strip, both ends of the round strip are placed in two slots respectively. The side walls of the slots are used to precisely limit the transverse movement of the round strip, ensuring that the round strip is in an accurate position in the transverse direction. The positioning element at the upper end of the positioning block can further position the round strip vertically, reducing the probability of the round strip shifting vertically and ensuring the stability of the round strip during processing. The elastic element will drive the two positioning blocks closer to each other in its natural state. The gripping block on one side of the positioning block provides a convenient gripping part for the operator. The operator can easily grip the gripping block and apply appropriate force to move the positioning block, thereby controlling the distance between the two ends of the round strip, reducing the probability of the round strip being too far or too close to the joint, and improving the bonding quality of the round strip.

[0008] Optionally, the positioning element includes a pressing block, a threaded rod, and a rotating head. The pressing block is located at the upper end of the positioning block, the threaded rod is fixed at the upper end of the positioning block and passes through the pressing block, and the rotating head is located at the end of the threaded rod away from the positioning block. The rotating head is threadedly connected to the threaded rod and is located at the upper end of the pressing block.

[0009] By adopting the above technical solution, the rotating head is threadedly connected to the threaded rod. By rotating the rotating head, it can move up and down along the threaded rod. When the rotating head moves down and pushes the pressing block, the pressing block can apply a relatively uniform force to the round strip, ensuring that the round strip can be positioned in various places in the slot, thus improving the stability of the round strip during bonding.

[0010] Optionally, anti-slip stripes are fixed on the outer side of the rotating head. When rotating, the anti-slip stripes are used to increase the friction between the hand and the rotating head.

[0011] By adopting the above technical solution, the anti-slip stripes enable operators to rotate the rotating head more easily and quickly, reducing the probability of hand slippage and the rotating head falling off, thereby shortening the adjustment time of the positioning components and improving the convenience of using the device.

[0012] Optionally, a baffle is provided at the upper end of the threaded rod, the baffle is arranged in a transverse direction, and both threaded rods are slidably connected to the baffle in a transverse direction.

[0013] By adopting the above technical solution, during the circular strip bonding process, the baffle blocks the parts of the circular strip that do not need to be bonded, reducing the probability of accidental bonding and improving the stability of the device.

[0014] Optionally, a receiving rod is fixed on one side of any holding block near another holding block, and an abutting rod is provided on one side of the other holding block. The abutting rod passes through the holding block and is threadedly connected to the holding block, and the abutting rod is inserted into the receiving rod.

[0015] By adopting the above technical solution, the abutment rod is threadedly connected to the holding block. Rotating the abutment rod controls the distance between it and the receiving rod, thereby adjusting the distance between the two holding blocks. The abutment between the abutment rod and the receiving rod controls the opening angle of the clamping fixture. Optionally, a limiting rod is fixed on one side of the holding block connected to the abutment rod, the abutment rod passes through the limiting rod, and the limiting rod limits the abutment rod during the movement of the abutment rod.

[0016] By adopting the above technical solution, in the processing of round strip, the gripping block needs to adjust the clamping position and force of the round strip by moving the abutment rod. The existence of the limiting rod ensures that the abutment rod can only move within a preset range, reducing positioning deviations caused by excessive or insufficient movement and improving the stability of the device.

[0017] Optionally, a limiting frame is provided at one end of any holding block away from the positioning block, and the limiting frame is hinged to the holding block. A limiting groove is provided at one end of another holding block away from the positioning block, and the limiting frame is inserted into the limiting groove.

[0018] By adopting the above technical solution, during the processing of round strip, the limiting frame is inserted into the limiting groove, so that the end of the clamping fixture that holds and fixes the round strip is in an open state, which facilitates the hot melting of the end of the round strip and improves the convenience of using the device.

[0019] Optionally, the pressing block is provided with a number of balls on the side near the positioning block. The balls are evenly distributed along the length of the pressing block, and the balls are rotatably connected to the pressing block.

[0020] By adopting the above technical solution, the uniform distribution of the balls can ensure that each ball can apply similar pressure to the circular belt, so that the circular belt remains stable during the positioning process, reducing the positioning deviation caused by uneven pressure. At the same time, the balls reduce the friction between the pressing block and the circular belt, avoiding damage to the surface of the circular belt.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. In its natural state, the elastic element will cause the two positioning blocks to move closer to each other. The gripping block on one side of the positioning block provides a convenient gripping position for the operator. The operator can easily grip the gripping block and apply appropriate force to move the positioning block, thereby controlling the distance between the two ends of the round belt, reducing the probability of the round belt being too far or too close to the joint, and improving the bonding quality of the round belt. 2. The presence of the limiting rod ensures that the abutment rod can only move within a preset range, reducing positioning deviations caused by excessive or insufficient movement and improving the stability of the device. 3. During the processing of the round strip, the limiting frame is inserted into the limiting groove, so that the end of the round strip clamped and fixed on the clamping fixture is in an open state, which facilitates the hot melting of the end of the round strip and improves the convenience of using the device.

[0026] The present application will be further described in detail below with reference to all the accompanying drawings.

[0027] This application discloses a fixing fixture for bonding round strips. Example

[0028] Reference Figure 1 and Figure 2 A fixing fixture for bonding round strips includes two positioning blocks 1. Each positioning block 1 has a slot 11 opened laterally. The two ends of the round strip 2 are respectively located in the two slots 11. The upper end of the positioning block 1 is provided with a positioning element 13. The positioning element 13 includes a pressing block 131, a threaded rod 132 and a rotating head 133. The pressing block 131 is located at the upper end of the positioning block 1. The threaded rod 132 is fixed at the upper end of the positioning block 1 and passes through the pressing block 131. The rotating head 133 is located at the end of the threaded rod 132 away from the positioning block 1. The rotating head 133 is threadedly connected to the threaded rod 132. By rotating the rotating head 133, it can move up and down along the threaded rod 132. The pressing block 131 is located at the upper end of the positioning block 1 and the rotating head 133 is located at the upper end of the pressing block 131.

[0029] Reference Figure 1 and Figure 2 When the rotating head 133 moves downward and pushes the pressing block 131, the pressing block 131 can apply a relatively uniform force to the round strip 2, ensuring that the round strip 2 can be positioned in various parts of the slot 11, thus improving the stability of the round strip 2 during bonding. Alternatively, a push rod can be used to press the pressing block 131 downward.

[0030] Reference Figure 2 The outer side of the rotating head 133 is provided with anti-slip stripes 1331. When the operator rotates the rotating head 133, the anti-slip stripes 1331 increase the friction between the hand and the rotating head 133, making it easier and faster for the operator to rotate the rotating head 133. This reduces the probability of the rotating head 133 falling off due to hand slippage, thereby shortening the adjustment time of the positioning component 13 and improving the convenience of using the device.

[0031] Reference Figure 1 Each side of the positioning block 1 is provided with a gripping block 12, which provides a convenient gripping position for the operator. The operator can easily grip the gripping block 12. An elastic element 121 is fixed between the two gripping blocks 12. In this solution, the elastic element 121 is a torsion spring. In its natural state, the elastic element 121 will drive the two positioning blocks 1 to move closer to each other. When bonding, the operator applies an appropriate force to move the positioning block 1, thereby controlling the distance between the two ends of the round strip 2 positioned on the positioning block 1, reducing the probability of the round strip 2 being too far or too close to be joined, and improving the bonding quality of the round strip 2.

[0032] Reference Figure 2 The pressing block 131 is provided with a number of balls 124 on the side near the positioning block 1. The balls 124 are evenly distributed along the length of the pressing block. The even distribution of the balls 124 can ensure that each ball 124 can apply similar pressure to the circular belt 2, so that the circular belt 2 remains stable during the positioning process and reduces the positioning deviation caused by uneven pressure. At the same time, the balls 124 reduce the friction between the pressing block 131 and the circular belt 2, and avoid damage to the surface of the circular belt 2.

[0033] Reference Figure 1 A guide rod 16 is provided between the two positioning blocks 1. A sliding hole matching the outer diameter of the guide rod 16 is opened on the positioning block 1. The guide rod 16 passes through the sliding hole, so that the positioning block 1 can slide freely along the length direction of the guide rod 16. During the bonding process of the round strip 2, the probability of the positioning block 1 deviating when moving is reduced, and the bonding accuracy of the round strip 2 is improved.

[0034] Reference Figure 3 A receiving rod 122 is fixed on one side of any holding block 12 near another holding block 12, and an abutment rod 123 is provided on one side of the other holding block 12. The abutment rod 123 passes through the holding block 12 and is threadedly connected to the holding block 12. By rotating the abutment rod 123, the distance between it and the receiving rod 122 can be controlled, thereby adjusting the distance between the two holding blocks 12. The opening angle of the clamping fixture is controlled by the abutment between the abutment rod 123 and the receiving rod 122.

[0035] Reference Figure 3A limiting rod 125 is fixed on one side of the holding block 12 connected to the abutment rod 123. The abutment rod 123 passes through the limiting rod 125. The presence of the limiting rod 125 ensures that the abutment rod 123 can only move within a preset range, reducing positioning deviations caused by excessive or insufficient movement and improving the stability of the device.

[0036] Reference Figure 1 The upper end of the threaded rod 132 is provided with a baffle 15, which is arranged in a transverse direction. Both threaded rods 132 are slidably connected to the baffle 15 in a transverse direction. During the bonding process of the round strip 2, the baffle 15 blocks the part of the round strip 2 that does not need to be bonded, reducing the probability of accidental bonding and improving the stability of the device. At the same time, it reduces the probability of the rotating head 133 detaching from the threaded rod 132 when rotating the rotating head 133, thus improving the stability of the device.

[0037] Reference Figure 3 A limiting frame 14 is provided at one end of the holding block 12 away from the positioning block 1. The limiting frame 14 is hinged to the holding block 12. A limiting groove 141 is provided at the other end of the holding block 12 away from the positioning block 1. During the processing of the round strip 2, the limiting frame 14 is inserted into the limiting groove 141, so that the end of the clamping fixture that holds and fixes the round strip 2 is in an open state, which facilitates the hot melting of the end of the round strip 2 and improves the convenience of using the device.

[0038] The implementation principle of a fixing fixture for bonding round strips in this application embodiment is as follows: When bonding round strip 2, the rotating head 133 is rotated. When the rotating head 133 rotates clockwise, under the action of the threaded drive and the vertical limiting action of the threaded rod 132, the rotating head 133 moves downward along the axis of the threaded rod 132. Its lower end face directly pushes the pressing block 131 and moves downward synchronously, so that the pressing block 131 and the positioning block 1 cooperate to position the end of the round strip 2. The elastic element 121 will drive the two positioning blocks 1 to move closer to each other in its natural state. The operator holds the holding block 12 to overcome the pre-tightening force of the elastic element 121 and adjusts the position of the positioning block 1, thereby controlling the distance between the two ends of the round strip 2, reducing the probability of the round strip 2 being too far or too close together, and improving the bonding quality of the round strip 2.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
