Description

Technical Field

[0001] This utility model relates to the field of transportation technology, and in particular to a gear clamping mechanism. Background Technology

[0002] In the booming development of industrial automation production and assembly, the clamping mechanism plays a crucial role. It is a key component for the smooth completion of core processes such as material handling and precise assembly of parts. Its performance is like a "stabilizing force" on the production line, directly and profoundly affecting key factors such as overall production efficiency, final product quality, and enterprise cost control.

[0003] Traditional gripping mechanisms mostly rely on mechanical limits or simple servo control technology for positioning. However, with the increasing complexity and diversity of industrial production scenarios and the ever-increasing precision requirements of products, these traditional methods have gradually revealed significant limitations in handling complex working conditions or high-precision operations, proving inadequate. Taking high-precision fields such as microelectronic component assembly and precision machining as examples, these production scenarios have almost demanding requirements for operational precision. Even minute positional deviations can lead to a series of serious consequences, ranging from assembly failure, waste of parts, and production delays, to impacting overall product performance and reducing product reliability and lifespan.

[0004] A closer examination of existing clamping mechanism design concepts reveals that they often focus on precise control of clamping force, while neglecting two crucial factors: the uniformity of stress distribution during clamping and the adaptability of the clamping mechanism to the surface characteristics of the object being clamped. In actual production, this design flaw is particularly problematic when handling brittle materials, thin-walled parts, or products with sensitive surfaces. Uneven stress distribution can easily lead to stress concentration in localized areas, causing deformation, scratches, or even breakage, severely impacting product yield and increasing production costs and resource waste.

[0005] Therefore, this application develops a gear clamping mechanism to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of this invention is to provide a gear clamping mechanism to solve the problems of insufficient or excessive clamping force in the prior art.

[0007] The technical solution of this utility model is: a gear clamping mechanism, comprising: Support base; A clamping device is mounted on the support base. The clamping device includes two opposing clamping parts, wherein at least one clamping part is slidably disposed on the support base, so that the two clamping parts can move closer to or further away from each other. The positioning device includes a movable part, which is mounted on the slidable clamping part and is movable between a first position and a second position along the sliding direction of the clamping part; wherein, when the movable part is in the first position, the two clamping parts are in a clamped state, and when the movable part is in the second position, the two clamping parts are in a released state.

[0008] Preferably, the positioning device further includes two photoelectric sensors, which are fixedly disposed at positions corresponding to the first position and the second position, respectively; the moving part is provided with a blocking part; when the moving part moves to the first position or the second position, the blocking part can block the photoelectric sensor at the corresponding position to generate a positioning signal.

[0009] Preferably, a driving device is also fixedly provided on the support base, and the output shaft of the driving device is connected to the slidable clamping part for driving the clamping part to move along its sliding direction.

[0010] Preferably, two guide rails are arranged in parallel on the support base, and the two clamping parts are slidably arranged on the corresponding guide rails. Racks are provided on the opposing sides of the two clamping parts. A gear is installed on the output shaft of the drive device. The gear meshes with the racks on the two clamping parts at the same time, so that when the drive device is running, it can synchronously drive the two clamping parts to move closer or further away from each other along the guide rails.

[0011] Preferably, the guide rail is a linear guide rail.

[0012] Preferably, both clamping parts have jaws, and the two jaws have clamping surfaces on their facing sides. The clamping surfaces are arc-shaped concave surfaces, and the two clamping surfaces are symmetrically arranged with respect to the center of the gear clamping mechanism.

[0013] Preferably, a flexible anti-slip material layer is embedded or adhered to the clamping surface.

[0014] Compared with the prior art, the advantages of this utility model are: (1) The positioning device is equipped with two slotted photoelectric sensors, which are fixed at the first position and the second position respectively. The moving part has a blocking part. When the moving part reaches the corresponding position, the blocking part is exactly in the slot of the photoelectric sensor. After the sensor is blocked, it sends a signal, which can accurately determine the position of the moving part. This greatly improves the position accuracy when clamping and releasing the gears, and effectively avoids problems such as unstable clamping or excessive clamping force causing product deformation due to inaccurate positioning. (2) The gear of the drive device meshes with the rack of the two clamping parts at the same time. During operation, the two clamping parts move at the same speed and displacement to ensure uniform clamping force and prevent the product from being deformed or damaged due to uneven force during clamping. (3) The jaws of the two clamping parts are provided with arc-shaped concave clamping surfaces on their facing sides, and the two arc-shaped concave surfaces are symmetrically arranged with respect to the center of the mechanism. When clamping the gear, the arc-shaped concave surfaces can evenly wrap around a part of the outer circumference of the product, avoiding excessive local force that could cause the product to deform or be damaged. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments: Figure 1 This is a schematic diagram of the structure of the gear clamping mechanism described in this utility model; Figure 2 This is a front view of the gear clamping mechanism described in this utility model; Figure 3 This is a top view of the gear clamping mechanism described in this utility model.

[0016] The components are: 1. Support base; 11. Guide rail; 2. Clamping device; 21. Clamping part; 211. Rack; 212. Gripper; 213. Clamping surface; 3. Positioning device; 31. Moving part; 32. Photoelectric sensor; 33. Blocking part; 4. Drive device; 41. Gear. Detailed Implementation

[0017] The present invention will be further described in detail below with reference to specific embodiments: like Figures 1-3 As shown, a gear clamping mechanism includes a support base 1, a clamping device 2, and a positioning device 3. The support base 1 provides a stable and reliable mounting platform for other devices, ensuring the stability of the entire mechanism during operation. The clamping device 2 is mounted on the support base 1 and includes two opposing clamping parts 21, with at least one clamping part 21 slidably mounted on the support base 1. This allows the two clamping parts 21 to move closer or further apart under external force, thereby clamping or releasing the product. The positioning device 3 includes a moving part 31, which is mounted on the slidable clamping part 21 and moves between a first position and a second position along the sliding direction of the clamping part 21. When the moving part 31 is in the first position, the two clamping parts 21 are clamped, securely holding the product and preventing it from falling off or shifting during processing or handling. When the moving part 31 is in the second position, the two clamping parts 21 are released, facilitating the placement of the product in a designated location or removal from the clamping mechanism.

[0018] In this embodiment, the positioning device 3 further includes two slotted photoelectric sensors 32, which are fixedly installed at corresponding first and second positions. The moving part 31 has a blocking part 33. When the moving part 31 moves to the first or second position, the blocking part 33 can move precisely to the slot position of the photoelectric sensor 32. When the photoelectric sensor 32 is blocked, it will emit a signal to determine the position of the moving part 31 at this time. This greatly improves the positional accuracy of the gear 41 clamping mechanism when clamping and releasing the gear 41, and effectively avoids problems such as unstable clamping or excessive clamping force caused by inaccurate positioning, which could lead to product deformation.

[0019] Specifically, two guide rails 11 are arranged in parallel on the support base 1, and two clamping parts 21 are slidably mounted on the corresponding guide rails 11 on the support base 1, so that the clamping parts 21 can move smoothly and steadily along the direction of the guide rails 11. The support base 1 is also equipped with a drive device 4, the output shaft of which is connected to a gear 41 and drives the gear 41 to rotate. Each of the two clamping parts 21 has a rack 211 on its facing side, which meshes well with the gear 41 on the drive device 4 to achieve stable power transmission. When the drive device 4 is running, its output shaft drives the gear 41 to rotate, and the gear 41 then transmits the rotational motion to the two racks 211 that mesh with it. Since the racks 211 are connected to the clamping parts 21, they synchronously drive the two clamping parts 21 to move closer or further apart along the guide rails 11 to achieve the clamping action. Furthermore, the gear 41 of the drive device 4 meshes with the rack 211 on the two clamping parts 21 at the same time, realizing synchronous driving of the two clamping parts 21. When the drive device 4 is running, the two clamping parts 21 can approach or move away from each other at the same speed and displacement, ensuring uniform clamping force and effectively preventing deformation or damage to the product due to uneven force during clamping.

[0020] Furthermore, such as Figure 2 As shown, the guide rail 11 is a linear guide rail 11, which has extremely high straightness and parallelism, and can provide precise guidance for the clamping part 21, so that the clamping part 21 will hardly deviate or wobble during the movement. Combined with the high precision characteristics of the rack 211 and gear 41 transmission, the entire clamping mechanism can achieve high precision clamping operation.

[0021] Furthermore, such as Figure 3As shown, each of the two clamping parts 21 has a jaw, and the opposing sides of the two jaws are provided with clamping surfaces 212. The clamping surfaces 212 are arc-shaped concave surfaces, and the two arc-shaped concave surfaces are symmetrically arranged with respect to the center of the gear 41 clamping mechanism. When the two clamping parts 21 approach each other and clamp the gear 41, the arc-shaped concave surfaces can evenly wrap around a portion of the outer circumference of the product, avoiding the problem of product deformation or damage due to excessive local force. In addition, a flexible anti-slip material layer is embedded or adhered to the arc-shaped concave surface. During the clamping process, the friction is enhanced by the flexible anti-slip material layer, effectively preventing slippage or detachment during clamping and handling, and improving the stability and reliability of clamping.

They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
