Description

Technical Field

[0001] This utility model relates to the field of clamping tooling technology, specifically a clamping tooling for tires. Background Technology

[0002] Tire manufacturing is a highly complex systems engineering project, encompassing multiple precision stages from raw material pretreatment, tire carcass molding, high-temperature vulcanization to final quality inspection. Tire clamps are key equipment in tire production, inspection, assembly, and repair, used to secure tires and ensure their stability during processing or testing. With advancements in tire manufacturing processes and increasing demands for automation, tire clamp technology is also continuously evolving.

[0003] However, in the later stages of tire production, finished tires are usually stored in multi-layer stacks. This storage method faces significant challenges in actual handling: the traditional manual method of picking up each tire individually is inefficient and seriously affects the speed of logistics turnover; while when using forklifts to transport and stack tires as a whole, the high center of gravity and poor stability of the tire stacks make them prone to tipping accidents during transportation, which not only poses safety hazards but may also cause product damage. Utility Model Content

[0004] The purpose of this invention is to provide a tire clamping fixture that solves the problem in the prior art that stacked tires are inconvenient to clamp and transport at the same time.

[0005] The technical solution of this utility model: A clamping fixture for tires, comprising a bracket and a clamping assembly, characterized in that the clamping assembly comprises:

[0006] A sliding component that is slidably connected to the bracket;

[0007] The telescopic frame includes multiple strut assemblies evenly distributed along the circumference of the frame. The strut assemblies are hinged to a sliding assembly. The sliding assembly can slide along the length of the frame under power drive, thereby driving the strut assemblies to extend and retract radially to clamp the tire.

[0008] Preferably, the sliding component includes:

[0009] Multiple sets of linkage assemblies, each set of linkage assemblies is arranged opposite to each other and is slidably connected to the bracket;

[0010] The bidirectional transmission mechanism is mounted on the bracket and connected to the linkage assembly. The transmission mechanism rotates under power drive, thereby driving multiple sets of linkage assemblies to move relative to each other, so as to realize the clamping of the tire by the telescopic frame.

[0011] Preferably, the bidirectional transmission mechanism includes:

[0012] A two-way lead screw is rotatably mounted on a bracket;

[0013] The drive motor is fixedly mounted on the bracket, and its output shaft is connected to one end of the double-acting lead screw via a coupling.

[0014] Two moving blocks are respectively engaged with two reverse threads of the bidirectional lead screw. Each set of connecting rod assemblies is rotatably connected to the two moving blocks. The rotation of the bidirectional lead screw drives the relative movement of each set of connecting rod assemblies.

[0015] Preferably, the bracket includes a mounting base and a mounting tube vertically disposed at the center of the mounting base;

[0016] The bidirectional lead screw is coaxially disposed inside the mounting tube, and the two moving blocks are slidably disposed inside the mounting tube.

[0017] Preferably, the mounting pipe wall is provided with axially distributed strip-shaped slots corresponding to each connecting rod assembly, and one end of the connecting rod assembly passes through the corresponding slot and is hinged to the corresponding moving block inside.

[0018] Preferably, the telescopic frame further includes:

[0019] The clamping component includes multiple arc-shaped plates evenly distributed along the periphery of the support, each arc-shaped plate corresponding to a strut assembly and disposed on the working surface of the strut assembly;

[0020] The telescopic rod is vertically mounted on the support assembly, and its two ends are fixedly connected to the bracket and the support assembly, respectively.

[0021] Preferably, the two ends of the support rod are provided with outwardly inclined flanges.

[0022] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0023] In its non-working state, this invention allows multiple support rod assemblies to be completely retracted around the support frame, forming a compact structural profile. This design enables the clamping fixture to be easily inserted into the hollow portion of the stacked tires. When handling operations are required, all support rod assemblies can expand outwards synchronously through precise drive of the bidirectional lead screw. The arc-shaped clamping plates on their outer sides can simultaneously form uniform contact with the inner walls of the multiple tire layers, thereby achieving the purpose of clamping multiple tires at once. Compared with existing handling methods, this significantly improves operational efficiency while ensuring transportation safety. Attached Figure Description

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0031] Example 1

[0032] like Figures 1-3 As shown, the present invention proposes a tire clamping fixture, including a bracket 1 and a clamping assembly. The clamping assembly includes a sliding assembly and a telescopic frame. The sliding assembly is slidably connected to the bracket 1. The telescopic frame includes a plurality of support rod assemblies 2 evenly distributed along the circumference of the bracket 1. The support rod assemblies 2 are hinged to the sliding assembly. Under power drive, the sliding assembly can slide along the length direction of the bracket 1, driving the support rod assemblies 2 to extend and retract radially to clamp the tire.

[0033] Specifically, the sliding assembly includes a linkage assembly 202 and a bidirectional transmission mechanism 3; the linkage assembly 202 is provided in multiple sets, each set of linkage assemblies 202 is arranged opposite to each other and is slidably connected to the bracket 1;

[0034] The bidirectional transmission mechanism 3 is mounted on the bracket 1 and connected to the linkage assembly 202. The transmission mechanism rotates under power drive, thereby driving multiple sets of linkage assemblies 202 to move relative to each other, so as to realize the clamping of the tire by the telescopic frame.

[0035] Specifically, the bidirectional transmission mechanism 3 includes a bidirectional lead screw 302, a drive motor 301, and a moving block 303; the bidirectional lead screw 302 is rotatably mounted on the bracket 1; the drive motor 301 is fixedly mounted on the bracket 1, and its output shaft is connected to one end of the bidirectional lead screw 302 through a coupling; the moving block 303 is provided with two reverse threads that respectively engage with the two sections of the bidirectional lead screw 302, and each set of connecting rod assemblies 202 is rotatably connected to two moving blocks 303 respectively. Through the rotation of the bidirectional lead screw, each set of connecting rod assemblies 202 is driven to move relative to each other.

[0036] Specifically, the telescopic frame also includes clamping components and telescopic rods 203; the clamping components include multiple arc-shaped plates 204 evenly distributed along the periphery of the support frame 1, the arc-shaped plates 204 corresponding one-to-one with the support rod assembly 2 and set on the working surface of the support rod assembly 2;

[0037] The telescopic rod 203 is vertically mounted on the support rod assembly 2, and both ends of the telescopic rod 203 are fixedly connected to the bracket 1 and the support rod assembly 2, respectively.

[0038] Furthermore, the strut assembly 2 has outwardly inclined flanges 206 at both ends.

[0039] Working Principle: When this clamping fixture is in operation, the entire device is first installed on an external device, such as the end effector of a robotic arm. In the initial state, each support rod assembly 2 is in a retracted state, tightly arranged around the circumference of the support frame 1. After the robotic arm drives the clamping fixture to precisely position it in the hollow area of ​​the stacked tires, the drive motor 301 starts, driving the bidirectional lead screw 302 to rotate. At this time, the two moving blocks 303 move towards each other on the support frame 1, causing the connecting rod assemblies 202 to move relative to each other. Under this linkage, all support rod assemblies 2 synchronously expand radially outward until their outer arc-shaped plates 204 form a uniform pressing contact with the inner wall of the multi-layered stacked tires, thereby achieving a stable clamping of multiple tires in one operation. After clamping is complete, the robotic arm can safely transfer the entire stack of tires to the target position.

[0040] Example 2

[0041] like Figures 1-3 As shown, the present invention proposes a tire clamping fixture. Compared with the first embodiment, the frame in this embodiment includes a mounting base 101 and a mounting tube 102 vertically arranged in the center of the mounting base 101. The mounting base 101 is provided with a mounting flange for connecting with external equipment. A bidirectional lead screw is coaxially arranged inside the mounting tube 102, and two moving blocks 303 are slidably arranged inside the mounting tube 102.

[0042] Furthermore, the mounting tube 102 has axially distributed strip-shaped slots 103 that correspond to each connecting rod. One end of the connecting rod assembly 202 passes through the corresponding slot 103 and is hinged to the corresponding moving block 303 inside.

[0043] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
