Description

Technical Field

[0001] This invention relates to the field of gripping structure technology, and in particular to a gripping structure for machining mechanical workpieces. Background Technology

[0002] In the production process of machining mechanical workpieces, it is often necessary to use a gripping structure to control the gripping stability, positioning accuracy and transfer efficiency of the workpieces. This is to prevent the workpieces from falling off, shifting position or becoming disconnected from the processing equipment due to their diverse shapes and large weight differences, which would affect the machining quality, production line continuity and operational safety.

[0003] Existing gripping structures for machining workpieces have significant drawbacks in terms of ease of assembly and disassembly, as well as gripping stability. The assembly and disassembly process requires multiple bolts for fixation, and operators must align the bolt holes one by one and repeatedly tighten or loosen them. This is not only cumbersome and time-consuming, but also prone to difficulties in assembly and disassembly due to bolt corrosion or installation errors, increasing maintenance costs. At the same time, the gripping structure lacks a secondary reinforcement structure. When gripping heavy or smooth workpieces, relying solely on the initial clamping force can easily lead to workpiece loosening, displacement, or even detachment. This not only affects machining accuracy and efficiency but may also cause workpiece damage or safety accidents. Summary of the Invention

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example

[0026] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a gripping structure for machining mechanical workpieces. The gripping structure for machining mechanical workpieces includes a gripping component 1 and a connecting component 2.

[0027] By employing a collaborative design between gripping component 1 and connecting component 2, the obvious shortcomings of mechanical workpiece gripping structures, such as cumbersome assembly and disassembly and unstable gripping, are effectively resolved. On the one hand, traditional bolt fixing is abandoned, and a snap-on quick-locking structure is adopted, eliminating the need to align holes and repeatedly tighten or loosen bolts, making assembly and disassembly easy, avoiding corrosion and installation deviation problems, and reducing maintenance costs.

[0028] Specifically, the gripping component 1 includes a mechanical fastener 11, a fixed connector 17 is provided on the top of the mechanical fastener 11, an adjusting component 12 is embedded in the bottom of the mechanical fastener 11, a clamping component 13 is movably connected to the inner wall of the mechanical fastener 11, an mounting component 14 is fixed on the top of the mechanical fastener 11, a dustproof cover 15 is provided on the top of the mounting component 14, and a movable connector 16 is fixed on the top of the fixed connector 17.

[0029] Specifically, the connecting component 2 is located on top of the gripping component 1 and includes a transmission component 21 fixed to the top of the dustproof cover 15. A locking component 22 is provided at the bottom of the transmission component 21, and a driving component 23 is provided on the outside of the mounting component 14. Example

[0030] Reference Figures 2-5 This is the second embodiment of the present invention. Based on the previous embodiment, this embodiment focuses on optimizing the connection stability and power transmission efficiency between the grasping component and the connecting component. The specific structure is described below: Specifically, the mounting component 14 includes a first connecting seat 141 fixed to the top of the mechanical fastener 11, a connecting sleeve 142 fixed to the top of the first connecting seat 141, and an insertion hole 143 opened on the surface of the connecting sleeve 142.

[0031] The first connecting seat 141 is the core connection interface between the gripping component and the connecting component. It is fixed to the top of the mechanical fastener 11 to ensure a firm installation. The connecting sleeve 142 is fitted onto and mates with the transmission component 21 of the connecting component to improve the coaxiality of the two. The insertion hole 143 cooperates with the insertion rod 224 of the locking component 22 to achieve a rigid lock between the mounting component 14 and the transmission component 21, preventing relative rotation.

[0032] Specifically, the transmission component 21 includes a rotating sleeve 211 fixed to the bottom of the fixed connector 17, an anti-slip sleeve 212 is fitted on the surface of the rotating sleeve 211, a connecting plate 213 is fitted on the rotating sleeve 211, and a threaded plug post 214 is fixed to the bottom of the rotating sleeve 211.

[0033] The rotating sleeve 211 is fixed to the bottom of the fixed connector 17 and transmits the rotational power of the fixed connector 17; the anti-slip sleeve 212 increases the friction between the rotating sleeve 211 and the external contact parts to prevent slippage during power transmission; the connecting plate 213 provides an installation base for the locking part 22 and supports components such as the sliding vertical rod 221 and the fixed vertical plate 225; the threaded plug post 214 is inserted into the connecting sleeve 142 of the mounting part 14 and initially fixes the transmission part 21 and the mounting part 14 through threaded engagement, while transmitting rotational power.

[0034] Specifically, the locking component 22 includes a sliding vertical rod 221 that is slidably connected to the inner wall of the connecting plate 213. A first contact seat 229 is fixed at the bottom of the sliding vertical rod 221, a limit block 222 is fixed at the top of the sliding vertical rod 221, and a first spring 223 is sleeved on the surface of the sliding vertical rod 221. The first spring 223 is fixed to the bottom of the limit block 222 and the top of the connecting plate 213 respectively.

[0035] The sliding vertical rod 221 slides up and down along the inner wall of the connecting plate 213, transmitting the pressing force of the driving member 23; the first contact seat 229 cooperates with the second contact seat 234 of the driving member 23 to receive the external driving force; the limiting block 222 limits the maximum downward stroke of the sliding vertical rod 221 to prevent it from falling off the connecting plate 213; the first spring 223 provides an upward elastic restoring force for the sliding vertical rod 221, and after the driving member 23 removes the external force, it drives the sliding vertical rod 221 back to the initial position.

[0036] Specifically, the locking component 22 also includes a fixed vertical plate 225 fixed to the bottom of the connecting plate 213. The inner wall of the fixed vertical plate 225 is slidably connected to a plug rod 224 that mates with the plug hole 143. A second spring 226 is sleeved on the surface of the plug rod 224. A second pressing block 227 is fixed on one side of the plug rod 224. A first pressing block 228 that mates with the second pressing block 227 is sleeved on the surface of the sliding vertical rod 221.

[0037] The fixed vertical plate 225 limits the sliding trajectory of the plug rod 224; when the plug rod 224 is inserted into the plug hole 143 of the mounting part 14, it locks the relative position of the transmission part 21 and the mounting part 14, and releases the lock when it is pulled out; the second spring 226 provides a reset force for the plug rod 224 to ensure that the plug rod 224 retracts in the unlocked state; the first pressing block 228 moves down with the sliding vertical rod 221, pressing the second pressing block 227 to drive the plug rod 224 to extend, realizing automatic locking and forming a linkage logic of "drive-press-lock".

[0038] Specifically, the driving component 23 includes a threaded sleeve 231 sleeved on the surface of the first connecting seat 141, a fixing ring 232 sleeved on the surface of the threaded sleeve 231, a connecting rod 233 fixed on the surface of the fixing ring 232, and a second contact seat 234 that cooperates with the first contact seat 229 fixed on the top of the connecting rod 233.

[0039] The threaded sleeve 231 moves axially during rotation through its threaded engagement with the first connecting seat 141; the retaining ring 232 fixes the relative position of the threaded sleeve 231 and the connecting rod 233 to ensure synchronous power transmission; the connecting rod 233 drives the second contact seat 234 to move with the threaded sleeve 231, and the second contact seat 234 presses the first contact seat 229 upward to provide the driving force required for locking the locking component 22, without the need for an additional power source, thus simplifying the structural design. Example

[0040] Reference Figures 2-5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0041] When using this gripping structure for machining mechanical workpieces, the core assembly of the components revolves around "threaded connection + secondary locking". The specific operation process is as follows: First, a preliminary threaded connection is made. Manually hold the anti-slip sleeve 212 on the surface of the rotating sleeve 211 of the transmission component 21 and drive the rotating sleeve 211 to rotate downward. The threaded insertion post 214 at the bottom of the rotating sleeve 211 engages with the threaded inner wall of the first connecting seat 141 of the mounting component 14. Since the inner wall of the first connecting seat 141 is pre-set with the threaded insertion post 214, the rotating sleeve 211 can be gradually moved downward through the threaded transmission until the upper thread rotates to the limit position, thus completing the preliminary connection between the transmission component 21 and the mounting component 14.

[0042] Next, a secondary locking process is performed. The threaded sleeve 231 of the drive component 23 is rotated. The threaded sleeve 231 moves upward along the surface of the first connecting seat 141 through the threaded engagement with the surface of the first connecting seat 141. The threaded sleeve 231 drives the fixing ring 232 and the connecting rod 233 to move upward synchronously. The second contact seat 234 at the top of the connecting rod 233 moves upward accordingly and abuts and presses against the first contact seat 229 of the locking component 22.

[0043] After the first contact seat 229 is compressed, it drives the sliding vertical rod 221 to slide upward along the inner wall of the connecting plate 213. The first pressing block 228 on the surface of the sliding vertical rod 221 moves upward simultaneously, pressing the second pressing block 227 of the locking member 22. The second pressing block 227 drives the plug rod 224 to slide along the inner wall of the fixed vertical plate 225, compressing the second spring 226. Finally, the plug rod 224 is inserted into the plug hole 143 on the surface of the connecting sleeve 142 of the mounting member 14, completing the secondary locking between the transmission member 21 and the mounting member 14, ensuring a stable connection.

[0044] If disassembly is required, rotate the threaded sleeve 231 in the opposite direction to move it downward. The second contact seat 234 will no longer press against the first contact seat 229. The sliding vertical rod 221 will reset under the elastic force of the first spring 223. The first pressing block 228 will no longer press against the second pressing block 227. The plug rod 224 will disengage from the plug hole 143 under the elastic force of the second spring 226. Finally, rotate the rotating sleeve 211 in the opposite direction to disengage the threaded plug post 214 from the first connecting seat 141.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
