Description

Technical Field

[0001] This utility model relates to the field of hose processing technology, and in particular to a tooling for processing automotive hoses. Background Technology

[0002] The ends of automotive hoses require precision processing such as cutting, grinding, and drilling blind holes. The accuracy of these processes directly affects the sealing performance of subsequent assembly and vehicle safety, thus requiring high stability and precision in the processing.

[0003] Currently, the mainstream method uses a pair of clamp-like fixtures to hold and fix the hose by clamping the outer walls on both sides of the hose end, but this has obvious technical problems: 1. The clamping position and angle are fixed. When switching processes, it is necessary to manually loosen and adjust the hose or move the tool. It is easy to deviate from the reference and has low efficiency when processing in multiple directions.

[0004] 2. The hose is soft and has a smooth outer wall, resulting in uneven clamping force on both sides. If it is too loose, the hose will shake during processing; if it is too tight, the tube cavity will be deformed.

[0005] 3. The hoses come in various specifications, and the clamp adjustment range is limited. Thin hoses are easily damaged by clamps, while thick hoses cannot be clamped securely, requiring frequent clamp replacements, which increases costs and time. Summary of the Invention

[0006] The technical problem to be solved by this utility model is that the clamping device is fixed in place, which leads to low processing efficiency and easy errors when switching processing steps, as well as insufficient clamping stability.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a tooling for processing automotive hoses, including a base, a rotary table vertically rotatably mounted on the base, a lifting plate vertically slidably mounted on the top of the rotary table, and a clamping assembly hinged to the top of the lifting plate. The clamping assembly is cylindrical, with a fixed ring and radially telescopic clamping blocks at the movable end. The clamping blocks are evenly distributed on the inner side of the fixed ring, and a rotation limiting structure for the rotary table is provided on the base.

[0008] Preferably, the rotation limiting structure includes a gear coaxially fixed to the bottom of the rotary table and an arc-shaped tooth block vertically slidably connected to the base, the tooth block meshing with the gear.

[0009] Preferably, the base is threaded with bolts, the bolts are vertically arranged and distributed at both ends of the toothed block and pass through the toothed block, and the toothed block is slidably connected to the bolts.

[0010] Preferably, a guide rod is vertically fixed to the bottom of the lifting plate, the bottom end of the guide rod is located inside the rotating platform, and the guide rods are evenly distributed around the axis of the rotating platform. An electric push rod is vertically fixed in the middle of the rotating platform, and the lifting plate is installed on the output end of the electric push rod.

[0011] Preferably, a mounting base is vertically fixed to the top of the lifting plate, the clamping assembly is hinged to the top of the mounting base, and an electric pull rod is hinged between the bottom of the mounting base and the middle of the clamping assembly.

[0012] Preferably, the clamping assembly includes a cylindrical housing, the fixing ring is coaxially fixed to the outside of the movable end of the housing, the clamping block is radially slidably disposed inside the housing, an installation shaft is coaxially rotatably disposed inside the housing, and a transmission structure is provided between the installation shaft and the clamping block to drive the clamping block to reciprocate.

[0013] Preferably, the transmission structure includes a drive gear fixedly connected to the mounting shaft and a rack fixedly connected to the clamping block. The drive gear meshes with the rack. A guide block is fixedly provided inside the housing. A guide groove is provided on the clamping block for the guide block to insert into. The direction of the guide groove is parallel to the arrangement direction of the rack.

[0014] Preferably, the outer end wall of the clamping block is arc-shaped, and the outer end wall of the clamping block is provided with crisscrossing grooves.

[0015] Preferably, a connecting frame is fixedly provided at one end of the fixing ring, and a collar is coaxially fixedly connected to the connecting frame, the collar being detachably fitted onto the housing.

[0016] This utility model provides a tooling for processing automotive hoses, which has the following beneficial effects.

[0017] 1. This fixture, with its vertically rotatable rotary table on the base and a rotation limit structure, allows the hose to rotate 360° around a vertical axis, enabling adjustment of the processing direction without loosening or unloosening the clamps. Simultaneously, the lifting plate can slide vertically along the rotary table, and the clamping components can be adjusted for hinge angle via an electric pull rod. The combination of these three features allows the hose to quickly adapt to the positional requirements of different processes such as cutting, grinding, and blind hole drilling, avoiding frequent tool movements or hose adjustments by operators, reducing process changeover time, and eliminating the need for repeated clamping. This effectively avoids processing errors caused by datum offset, significantly improving multi-directional processing efficiency and accuracy.

[0018] 2. The clamping assembly adopts a design of a fixed ring and radial telescopic clamping blocks. The clamping blocks are evenly distributed inside the fixed ring, and the outer end wall is arc-shaped with longitudinal and transverse grooves. This allows the arc-shaped wall to fit against the outer wall of the hose, increasing the contact area and preventing excessive local stress that could cause deformation of the tube cavity. The grooves also increase friction and prevent the hose from slipping due to the smooth outer wall. At the same time, the telescopic amount of the clamping blocks is precisely controlled by the transmission structure, and the clamping force can be adjusted according to the hardness of the hose. This avoids both excessive looseness, which could cause shaking during processing, and excessive tightness, which could cause deformation. This ensures the structural integrity of the hose after processing and the sealing performance of subsequent assembly. Attached Figure Description

[0024] like Figure 1-4 As shown, this utility model provides a tooling for processing automotive hoses, including a base 1, a rotary table 2 vertically rotatably mounted on the base 1, a lifting plate 7 vertically slidably mounted on the top of the rotary table 2, and a clamping assembly 9 hinged to the top of the lifting plate 7. The clamping assembly 9 is cylindrical, and its movable end is provided with a fixing ring 13 and a radially telescopic clamping block 17. The clamping block 17 is evenly distributed on the inner side of the fixing ring 13. The base 1 is provided with a rotation limiting structure for the rotary table 2.

[0025] The base 1 is directly fixed on the worktable, and the rotary table 2 is rotatably mounted on the base 1 through bearings. With the help of the rotation limit structure, the processing direction can be locked after the processing direction of the hose is adjusted. By adjusting the height of the lifting plate 7, the clamping assembly 9 can be adjusted in height. The clamping assembly 9 is hinged to the top of the lifting plate 7 and can be adjusted in the vertical direction to meet the processing requirements of the hose.

[0026] like Figure 1 As shown. The rotation limiting structure includes a gear 3 coaxially fixed to the bottom of the rotary table 2 and an arc-shaped toothed block 4 vertically slidably connected to the base 1, with the toothed block 4 meshing with the gear 3. When it is necessary to adjust the angle of the rotary table 2, the toothed block 4 is slid upward to separate from the gear 3. Then, the rotary table 2 is rotated to a suitable processing angle, and then the toothed block 4 is controlled to move downward to mesh with the gear 3, thereby limiting the rotation of the rotary table 2. Of course, the angle of the rotary table 2 needs to be finely adjusted during the downward movement of the toothed block 4 to ensure smooth meshing.

[0027] like Figure 1 As shown. Bolts are threaded onto the base 1, vertically positioned and distributed at both ends of the toothed block 4, penetrating the toothed block 4. The toothed block 4 is slidably connected to the bolts. A convenient design utilizes long bolts, which act as sliding rods, providing not only sliding support for the toothed block 4 but also limiting its horizontal movement.

[0028] like Figure 1 As shown. A guide rod 6 is vertically fixed to the bottom of the lifting plate 7. The bottom end of the guide rod 6 is located inside the rotating platform 2, and the guide rods 6 are evenly distributed around the axis of the rotating platform 2. An electric push rod 5 is vertically fixed in the middle of the rotating platform 2, and the lifting plate 7 is mounted on the output end of the electric push rod 5. By setting no fewer than two guide rods 6, the movement of the lifting plate 7 is guided, and the lifting plate 7 is also supported to prevent it from shifting due to uneven force on the top.

[0029] like Figure 1 As shown. A mounting base 8 is vertically fixed to the top of the lifting plate 7. The clamping assembly 9 is hinged to the top of the mounting base 8. An electric pull rod 10 is hinged between the bottom of the mounting base 8 and the middle of the clamping assembly 9. The mounting base 8, acting as an ear plate, is directly fixed to the top center of the lifting plate 7. The end of the clamping assembly 9 is hinged to the top of the mounting base 8. By controlling the length of the electric pull rod 10, the angle of the clamping assembly 9 in the horizontal direction is adjusted to meet the needs of hose processing.

[0030] like Figure 1-3 As shown. The clamping assembly 9 includes a cylindrical housing. The fixing ring 13 is coaxially fixed to the outer side of the movable end of the housing. The clamping block 17 is radially slidably disposed inside the housing. A mounting shaft 14 is coaxially rotatably disposed inside the housing. A transmission structure is provided between the mounting shaft 14 and the clamping block 17 to drive the clamping block 17 to reciprocate. A motor is installed inside the housing. One end of the mounting shaft 14 is coaxially fixed to the output shaft of the motor. The motor reciprocates to drive the mounting shaft 14 to rotate, which, in conjunction with the transmission structure, drives the clamping block 17 to reciprocate. The clamping block 17 moves toward the fixing ring 13, thereby clamping the end of the hose from the inside and outside in conjunction with the fixing ring 13.

[0031] like Figure 3As shown. The transmission structure includes a drive gear 15 fixedly connected to the mounting shaft 14 and a rack 16 fixedly connected to the clamping block 17. The drive gear 15 meshes with the rack 16. A guide block 18 is fixedly disposed inside the housing. The clamping block 17 has a guide groove 19 for the guide block 18 to insert into. The direction of the guide groove 19 is parallel to the arrangement direction of the rack 16. Through the guide groove 19 and the guide block 18, the movement of the clamping block 17 is guided, so that when the drive gear 15 drives the rack 16 to move, the clamping block 17 can be accurately pushed to move accurately. Moreover, the guide block 18 and the guide groove 19 can also cooperate with the drive gear 15 to provide stable support for the clamping block 17.

[0032] like Figure 3 As shown. The outer end wall of the clamping block 17 is arc-shaped, and crisscrossing grooves are provided on the outer end wall of the clamping block 17. By providing grooves to enhance friction, and by making the end of the clamping block 17 arc-shaped, the contact area can be increased, and deformation of the tubing caused by excessive local compression can be avoided.

[0033] like Figure 2 As shown. A connecting bracket 12 is fixedly provided at one end of the fixing ring 13, and a collar 11 is coaxially fixedly connected to the connecting bracket 12. The collar 11 is detachably fitted onto the housing. By using the detachable collar 12, different sizes of fixing rings 13 can be selected according to the size of the hose to be processed, and they can be locked onto the housing with bolts.
