Description

Technical Field

[0001] This utility model relates to the field of clamping fixture technology, specifically a multi-cavity integrated clamping fixture for granular parts. Background Technology

[0002] In machining, electronic assembly, and other fields, clamping and securing particulate components is a common and critical process. Traditional clamping methods typically use single-piece clamping, achieved by rotating screws. However, this method has the following problems: Low efficiency: Only one piece can be clamped at a time, and the clamping and unclamping process is cumbersome and time-consuming. Unstable clamping force: The clamping force of the screws depends on the operator's experience, making it difficult to ensure consistency and potentially leading to clamping that is too tight or too loose. Difficulty in controlling clamping force: The screw-rotating clamping method cannot precisely control the clamping force, easily damaging the material or causing insecure clamping. Frequent operation: The clamping and unclamping of materials requires frequent operation, making it impossible for one person to operate multiple machines, thus limiting the improvement of production efficiency. Utility Model Content

[0003] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a multi-cavity integrated clamping fixture for granular parts, solving the problems of low efficiency, unstable force, and difficulty in controlling the clamping force of traditional screw clamping methods, thereby improving the clamping efficiency and clamping stability of granular parts.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A multi-cavity integrated clamping fixture for granular parts includes a base plate, a support plate, push rods, and multiple clamping assemblies. The support plate is vertically fixed to the upper part of the base plate. A through hole is provided on the support plate from top to bottom, and the push rod is slidably inserted into the through hole from top to bottom. The clamping assemblies are disposed on one side of the support plate. Multiple clamping assemblies are arranged in an equally spaced array on one side of the support plate. Each clamping assembly includes a guide post, a spring, and a clamping block. A horizontal guide hole is provided in the support plate, and the guide post is slidably disposed in the horizontal guide hole. The spring is sleeved on the guide post, and one end abuts against the support plate. One end is fixed to the guide post; the clamping block is placed on the side of the support plate away from the spring, and one end of the guide post is fixedly connected to the clamping block; a clamping claw is fixedly provided on the upper end of the clamping block; a clamping groove adapted to the clamping claw is provided on the support plate; a push rod is fixedly provided on the side of the clamping block near the spring; a sliding hole adapted to the push rod is provided on the support plate, the sliding hole is connected to the through hole, and the push rod is movably inserted into the sliding hole; a first guide inclined surface is provided on the lower end face of the push rod, and a second guide inclined surface adapted to the first guide inclined surface is provided on the push rod, and the first guide inclined surface and the second guide inclined surface slide in contact.

[0006] Preferably, it also includes a limiting rod; the support plate is provided with a limiting hole from the top end downwards, and the limiting hole is parallel to the through hole; the limiting rod is slidably inserted into the limiting hole from the top end downwards, and the limiting rod is parallel and spaced apart from the gripper.

[0007] Preferably, there are two limiting holes; the two limiting holes are symmetrically arranged on both sides of the through hole.

[0008] Preferably, a pull rod is fixedly provided at the top of the push rod.

[0009] Preferably, the clamping block has two guide posts, which are symmetrically arranged on both sides of the clamping jaw, and the horizontal guide holes correspond to two guide posts.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] Improve clamping efficiency:

[0012] The multi-cavity integrated design supports simultaneous clamping of multiple granular parts, significantly reducing clamping time. The push rod insertion and removal operation is simple and quick, requiring no screw rotation, greatly improving operational efficiency.

[0013] Stable clamping force:

[0014] The clamping force is achieved through the elasticity of the spring, resulting in uniform and controllable clamping force, thus avoiding the problem of unstable clamping force in traditional screw clamps. The matching design of the jaws and clamping grooves ensures that the granular parts are firmly fixed without loosening or over-tightening.

[0015] Precise control of holding force:

[0016] The spring constant is precisely calculated to provide stable holding force, preventing material damage or insecure clamping. The beveled design of the push rod and top rod further optimizes the control of the clamping force.

[0017] Supports one person operating multiple devices:

[0018] The fixture is easy to operate, with rapid clamping and releasing processes, allowing operators to manage multiple machines simultaneously, thus improving production efficiency. It also reduces the labor intensity of operators and lowers labor costs.

[0019] Wide range of applications:

[0020] Suitable for granular parts of various sizes and shapes, the clamping grooves and jaws can be adjusted to meet the clamping requirements of different materials. It can be widely used in machining, electronic assembly, precision manufacturing, and other fields.

[0021] Simple structure and easy maintenance:

[0022] The fixture has a reasonable structural design, and its components are easy to disassemble and replace, resulting in low maintenance costs. Key components such as springs and guide pillars adopt standardized designs, facilitating procurement and replacement. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] like Figures 1 to 3As shown, a multi-cavity integrated clamping fixture for granular parts includes a base plate 1, a support plate 5, a push rod 4, and multiple clamping components 2. The base plate 1 provides support and fixation. The support plate 5 is vertically fixed to the upper part of the base plate 1. The support plate 5 serves as the main support for clamping. A through hole 53 is provided on the support plate 5 from top to bottom. The push rod 4 is slidably inserted into the through hole 53 from the upper end of the through hole 53. The push rod 4 can be pulled up to pull it out of the through hole 53. The clamping assembly 2 is disposed on one side of the support plate 5; multiple clamping assemblies 2 are arranged in an equally spaced array on one side of the support plate 5; the clamping assembly 2 is used to apply clamping force to the granular parts and fix the granular parts on the support plate 5; the clamping assembly 2 includes a guide post 22, a spring 21, and a clamping block 23; a horizontal guide hole 55 is provided in the support plate 5, and the guide post 22 is slidably disposed in the horizontal guide hole 55; the spring 21 is sleeved on the guide post 22, and one end abuts against the support plate 5. The other end is fixed to the guide post 22; the clamping block 23 is placed on the side of the support plate 5 away from the spring 21, and one end of the guide post 22 is fixedly connected to the clamping block 23; a clamping claw 24 is fixedly provided on the upper end of the clamping block 23; a clamping groove 51 adapted to the clamping claw 24 is provided on the support plate 5; the spring 21 pushes the guide post 22, so that the clamping block 23 is pressed tightly against the side of the support plate 5, and the granular parts are clamped and fixed in the clamping groove 51 by the clamping claw 24; the side of the clamping block 23 near the spring 21 is fixed A push rod 25 is provided, which is perpendicular to the gripper 24 and extends horizontally. The support plate 5 is provided with a sliding hole 54 that matches the push rod 25. The sliding hole 54 is connected to the through hole 53, and the push rod 25 is movably inserted into the sliding hole 54. The lower end face of the push rod 4 is provided with a first guide slope 42, and the push rod 25 is provided with a second guide slope 26 that matches the first guide slope 42. The first guide slope 42 and the second guide slope 26 are in sliding contact. When the push rod 4 is not inserted into the through hole 53, under the action of the spring 21, the front end of the push rod 25 passes through the sliding hole 54 and is inserted into the through hole 53. At this time, the gripper 24 is located in the clamping groove 51. When the push rod 4 is inserted into the through hole 53, the first guide slope 42 of the push rod 4 contacts the second guide slope 26 of the push rod 25, and the push rod 25 is pushed out of the through hole 53. At this time, the spring 21 is compressed, and the gripper 24 moves out of the clamping groove 51. There is a gap between the gripper 24 and the clamping groove 51. This gap is used to place the granular parts. After the push rod 4 is pulled out of the through hole 53, the spring 21 pushes the clamping block 23 to reset, and the granular parts are clamped and fixed in the clamping groove 51 by the gripper 24.

[0030] In this embodiment, a limiting rod 3 is also included; a limiting hole 52 is provided on the support plate 5 from the top to the bottom, and the limiting hole 52 is parallel to the through hole 53; the limiting rod 3 is slidably inserted into the limiting hole 52 from the top to the bottom, and the limiting rod 3 is parallel and spaced apart from the gripper 24. After the limiting rod 3 is inserted into the limiting hole 52, the limiting rod 3 is located on one side of the clamping groove 51. The limiting rod 3 is used to position the granular part to be clamped, which facilitates fixing the granular part in a specific position in the clamping groove 51.

[0031] In this embodiment, two limiting holes 52 are configured; the two limiting holes 52 are symmetrically arranged on both sides of the through hole 53. According to the usage requirements, the limiting rod 3 is inserted into one of the limiting holes 52 to position the part.

[0032] In this embodiment, a pull rod 41 is fixedly provided on the top of the push rod 4 to facilitate the insertion and removal of the push rod 4.

[0033] In this embodiment, two guide posts 22 are configured on the clamping block 23, and the two guide posts 22 are symmetrically arranged on both sides of the clamping jaw 24. Two horizontal guide holes 55 are configured corresponding to the guide posts 22. The arrangement of the two guide posts 22 makes the sliding of the clamping block 23 more stable.

[0034] How to use

[0035] 1. Preparation

[0036] Ensure that the base plate 1, support plate 5, push rod 4, clamping assembly 2 and other components of the fixture are intact.

[0037] Check whether components such as spring 21, guide post 22, clamping block 23, and gripper 24 are flexible and free from jamming.

[0038] Prepare the granular parts that need to be clamped and confirm that their dimensions are compatible with the clamping groove 51.

[0039] 2. Install limit rod 3

[0040] Based on the positioning requirements of the granular parts, the limiting rod 3 is inserted into the limiting hole 52 on the support plate 5.

[0041] The support plate 5 has two symmetrically arranged limiting holes 52, one of which can be selected to insert the limiting rod 3 as needed.

[0042] After inserting the limiting rod 3 into the limiting hole 52, ensure that it is set parallel and spaced apart from the gripper 24 for positioning the granular parts.

[0043] 3. Place the granular parts

[0044] Pull the top rod 41 of the push rod 4 to insert the push rod 4 into the through hole 53 of the support plate 5.

[0045] The first guide ramp 42 of the push rod 4 will contact the second guide ramp 26 of the push rod 25, pushing the push rod 25 to move outward.

[0046] After the push rod 25 moves, the spring 21 is compressed, and the gripper 24 moves out of the clamping groove 51, forming a gap.

[0047] Place the granular part into the clamping groove 51, ensuring that it contacts the limit rod 3 (if any) for accurate positioning.

[0048] 4. Clamping granular parts

[0049] Slowly pull out push rod 4 so that the first guide slope 42 of push rod 4 separates from the second guide slope 26 of push rod 25.

[0050] Spring 21 regains its elasticity, pushing clamp 23 to move towards support plate 5.

[0051] The gripper 24 moves with the clamping block 23 to clamp and fix the granular parts in the clamping groove 51.

[0052] Confirm that the granular parts are firmly clamped and not loose.

[0053] 5. Disassemble granular parts

[0054] After completing the operation, pull the lever 41 at the top of the push rod 4 to insert the push rod 4 into the through hole 53.

[0055] The first guide ramp 42 of the push rod 4 pushes the top rod 25 again, compressing the spring 21, causing the gripper 24 to move out of the clamping groove 51.

[0056] Remove the granular parts.

[0057] Pull out push rod 4 to reset gripper 24 and prepare for the next operation.

[0058] 6. Precautions

[0059] Avoid using excessive force during operation to prevent damage to the gripper 24, spring 21, or push rod 4.

[0060] Regularly check the elasticity of spring 21 and the flexibility of guide post 22, and lubricate or replace as necessary.

[0061] Ensure that the size of the granular part matches the clamping groove 51 to avoid insecure clamping or damage to the fixture due to size mismatch.
