Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a clamping fixture for a water inlet connector of a water heater. Background Technology

[0002] The water inlet connector of the water heater is the bridge connecting the household water pipe network and the water heater, ensuring that the water heater can receive water normally; such as Figure 1 The water inlet connector shown is bent, with two connecting blocks on its arc-shaped outer wall. These connecting blocks have through holes for fixing the inlet connector to the water heater. During manufacturing, the inlet connector is integrally formed using hot-forging. Due to process limitations, the integrally formed connecting blocks require manual planar drilling. Typically, a chuck is used to fix the inlet connector to the working plane of a milling machine, then the plane is milled. Finally, the inlet connector is fixed to the working platform of a drilling machine using another chuck, and the hole is drilled.

[0003] However, in existing technologies, due to the irregular shape of the water inlet connector, the clamping force is easily unevenly distributed when the chuck is clamped, leading to loosening or displacement of the water inlet connector and causing inaccurate drilling positions. In addition, one chuck can only clamp one water inlet connector at a time, and the workpiece must be removed after processing before installing another workpiece, resulting in low processing efficiency. Utility Model Content

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0005] A clamping fixture for a water inlet connector of a water heater includes an upper mounting base and a lower mounting base connected vertically. A plurality of first clamping blocks are fixedly connected to the upper end face of the upper mounting base. The plurality of first clamping blocks are arranged in a matrix, and the plurality of first clamping blocks in each row are connected by guide rods. A second clamping block and a third clamping block are provided between each pair of adjacent first clamping blocks in each row. The second and third clamping blocks are respectively adapted to the two first clamping blocks in a one-to-one correspondence. Both the second and third clamping blocks are slidably adapted to the guide rods. A plurality of driving components are provided on the lower end face of the upper mounting base, each driving component corresponding to one of the second and third clamping blocks. The output shaft of the driving component is provided with a pressure block, which penetrates the upper end face of the upper mounting base and is located between the second and third clamping blocks.

[0006] Furthermore, a plurality of the first clamping blocks are arranged in a matrix of at least two rows and two columns, with the first clamping blocks in adjacent rows being staggered and centrally symmetrical, for simultaneously clamping multiple water inlet connectors to be processed and completing the batch processing of water inlet connectors, resulting in high processing efficiency.

[0007] Further, the first clamping block and the corresponding second clamping block, the first clamping block and the corresponding third clamping block are provided with elastic members.

[0008] Further, the pressing block is inverted conical.

[0009] Further, the side surface of the second clamping block and the third clamping block is inclined surface, which is matched with the pressing block.

[0010] Further, the first clamping block and the second clamping block are provided with the chip removal hole. The chip removal hole is used for avoiding the milling cutter cutting the first clamping block and the second clamping block, and also enabling the drill processing generated debris to fall from the chip removal hole to the lower mounting seat, avoiding the influence of the debris on the processing.

[0011] The utility model discloses the beneficial effects of:

[0012] 1, the second clamping block and the third clamping block are respectively matched with two first clamping blocks one by one and are used for clamping the water inlet connector in all directions, so that the water inlet connector is uniformly stressed, and the stability of the water inlet connector during processing is improved.

[0029] Reference Figures 2-8 An embodiment of the utility model shown in the drawing is:

[0030] A clamping fixture for a water inlet connector of a water heater includes an upper mounting base 1 and a lower mounting base 2 connected vertically. The upper mounting base 1 and the lower mounting base 2 are rectangular steel plates of the same shape, arranged parallel to each other vertically. The upper mounting base 1 and the lower mounting base 2 are fixedly connected by several support plates. Specifically, the upper and lower ends of the support plates can be welded to the lower end face of the upper mounting base 1 and the upper end face of the lower mounting base 2, respectively. In order to facilitate the disassembly of the upper mounting base 1 and the lower mounting base 2 and the maintenance of the fixture, protruding edges can be provided on the outer walls of the upper and lower ends of the support plates and respectively fit against the lower end face of the upper mounting base 1 and the upper end face of the lower mounting base 2. At the same time, threaded holes are opened at the protruding edges and at corresponding positions of the upper mounting base 1 and the lower mounting base 2, and the connection can be fixed by screws.

[0031] A plurality of first clamping blocks 3 are fixedly connected to the upper end face of the upper mounting base 1. The plurality of first clamping blocks 3 are arranged in a matrix of at least two rows and two columns. In this utility model, the matrix arrangement of the first clamping blocks 3 is four rows and five columns, which can clamp multiple water inlet connectors to be processed at the same time and complete the batch processing of water inlet connectors, resulting in high processing efficiency.

[0032] In this invention, several first clamping blocks 3 in each row are connected by guide rods 4, such as... Figure 2 As shown, the lower end of the first clamping block 4 is fixedly connected to the upper mounting base 1, specifically by welding. A first connecting hole is provided on the side end of the first clamping block 4, which is interference-fitted with the guide rod 4 to fix the guide rod 4 and prevent it from moving. Between each row of two adjacent first clamping blocks 3, a second clamping block 5 and a third clamping block 6 are sequentially provided. Both the second clamping block 5 and the third clamping block 6 have second connecting holes, the diameter of which is slightly larger than the diameter of the guide rod 4, allowing the second clamping block 5 and the third clamping block 6 to slide on the guide rod 4. In this invention, two parallel guide rods 4 are provided, meaning the second clamping block 5 and the third clamping block 6 slide and adapt to the two guide rods 4, preventing the second clamping block 5 and the third clamping block 6 from deflecting during sliding. Figure 2 and Figure 3 As shown, the second clamping block 5 and the third clamping block 6 are respectively adapted to the two first clamping blocks 3 to clamp the tubular outer wall of the water inlet connector. The right end face of the second clamping block 5 is adapted to clamp one water inlet connector by corresponding to the left end face of the right first clamping block 3, and the left end face of the third clamping block 6 is adapted to clamp the other water inlet connector by corresponding to the right end face of the left first clamping block 3.

[0033] Specifically, such as Figures 3-5As shown, the left end face of the first clamping block 3 and the right end face of the second clamping block 5 are provided with mutually buckling and matching arc-shaped bosses, the right end face of the first clamping block 3 and the left end face of the third clamping block 5 are provided with mutually buckling and matching arc-shaped bosses, the arc-shaped bosses are obliquely arranged, the oblique angle is the same as the oblique angle of the water inlet connector, the arc-shaped bosses have arc-shaped edges, the arc of the arc-shaped edges is the same as the arc of the outer wall of the water inlet connector, the arc-shaped bosses and the arc-shaped edges are used for matching and supporting the water inlet connector, and are completely matched with the arc surface of the water inlet connector, so that the water inlet connector can be uniformly stressed, and the connecting block on the water inlet connector is located on the upper end face of the first clamping block 3, thereby facilitating the milling machine to process the connecting block.

[0034] The lower end face of the upper mounting seat 1 is provided with a plurality of driving members 7, the driving members 7 are fixedly installed on the lower end face of the upper mounting seat 1 in a bolt connection manner, the stability during operation is ensured, and at the same time, gaps are left between the upper mounting seat 1 and the lower mounting seat 2 for placing the driving members 7. The plurality of driving members 7 correspond to the second clamping block 5 and the third clamping block 6 one by one, the output shaft of the driving member 7 is provided with a pressing block 8, the pressing block 8 penetrates through the upper end face of the upper mounting seat 1 and is located between the second clamping block 5 and the third clamping block 6, the pressing block 8 is inverted conical and is used for applying pressing force to the corresponding second clamping block 5 and third clamping block 6, and the left side face of the second clamping block 5 and the right side face of the third clamping block 6 are both inclined faces which are matched with the pressing block 8. When the output shaft of the driving member 7 stretches upward, the pressing block 8 moves upward, and at this time, the second clamping block 5 and the third clamping block 6 can slide on the guide rod 4; when the output shaft of the driving member 7 contracts downward, the pressing block 8 gradually moves downward and extrudes the second clamping block 5 and the third clamping block 6, so that the second clamping block 5 and the third clamping block 6 clamp the water inlet connector.

[0035] In order to facilitate quick replacement and maintenance of the pressing block 8, a threaded through hole is formed in the upper end of the pressing block 8 and is used for threaded connection with the output shaft of the driving member 7.

[0036] In the utility model, as shown in Figure 2 、 Figure 3 and Figure 8 , when the first clamping block 3, the second clamping block 5 and the third clamping block 6 clamp the water inlet connector, one end of the water inlet connector will extend out of the clamping block, which affects the clamping of the adjacent water inlet connector, therefore, the first clamping blocks 3 of the adjacent two rows of the first mounting seat 1 are staggered and centrosymmetric, so that the water inlet connectors extending out between the adjacent rows can be staggered and arranged, the number of clamped water inlet connectors can be increased on the limited area, and the processing efficiency is improved.

[0037] After the water inlet joint is processed, in order to realize automatic loosening of the first clamping block 3, the second clamping block 5 and the third clamping block 6, facilitate the water inlet joint to be taken down, the first clamping block 3 and the corresponding second clamping block 5, the first clamping block 3 and the corresponding third clamping block 6 are each provided with an elastic piece 9, the elastic piece 9 can use the existing spring, the first clamping block 3, the second clamping block 5 and the third clamping block 6 are each provided with a mounting groove corresponding to the elastic piece 9, the elastic piece 9 is mounted in the mounting groove, when the first clamping block 3, the second clamping block 5 and the third clamping block 6 clamp the water inlet joint, the elastic piece 9 is in a compressed state, when the pressing block 8 moves upward, the second clamping block 5 and the third clamping block 6 automatically slide under the action of the elastic force of the elastic piece 9, loosen the water inlet joint, facilitate the operator to take the water inlet joint.

[0038] The working process of the utility model is:

[0039] Firstly, the lower mounting seat 2 can be fixedly installed on the workbench of the milling machine through bolts, then the water inlet joint is sequentially placed between the first clamping block 3 and the second clamping block 5 and between the first clamping block 3 and the third clamping block 6, the driving part 7 is started to move the pressing block 8 downward to press the second clamping block 5 and the third clamping block 6 to clamp the water inlet joint, the milling machine is started to process the connecting block on the water inlet joint, the end face is polished to improve the precision of the end face and process the through hole. When the through hole on the connecting block is processed by the milling machine, in order to avoid damage of the first clamping block 3 and the second clamping block 5 by the milling cutter, the first clamping block 3 and the second clamping block 5 are each provided with a chip falling hole 10 corresponding to the connecting block, the chip falling hole 10 is a circular groove, the diameter is equal to or greater than the diameter of the through hole on the connecting block, when the milling cutter finishes processing the through hole, the milling cutter will move downward into the chip falling hole 10, avoiding cutting the first clamping block 3 and the second clamping block 5 by the milling cutter, and the debris generated by drilling can also fall into the lower mounting seat 2 from the chip falling hole, avoiding the influence of the debris on the processing.
