Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of machining technology, and more specifically, to a dovetail vise clamp. Background Technology

[0002] The clamping method of a gauge vise is relatively simple, mostly using a parallel jaw structure. It is only suitable for workpieces with regular shapes and relatively fixed dimensions. For parts with special shapes, such as those with dovetail grooves, traditional jaws cannot fit tightly and cannot provide stable and uniform clamping force. This causes the workpiece to easily shift or wobble during processing, which seriously affects the processing accuracy and results in a high scrap rate. This problem is particularly prominent in industries with stringent requirements for part precision, such as aerospace and precision mold manufacturing. Taking the processing of aerospace stringer parts as an example, traditional clamping methods not only have high tooling manufacturing costs but also extremely low processing efficiency and high labor intensity for workers. Traditional vises lack flexibility in adjustment. When machining workpieces of different sizes or shapes, a lot of time is often spent changing the jaws and readjusting the fixture parameters. The operation is cumbersome, time-consuming, and labor-intensive, resulting in prolonged equipment downtime and a significant reduction in production efficiency. Moreover, traditional fixtures are not stable enough when dealing with complex working conditions. During high-speed cutting and heavy-duty milling, the fixtures are prone to deformation or loosening due to vibration, uneven force, and other factors, which further reduces the machining quality and may also cause safety hazards. Utility Model Content

[0003] To overcome the above-mentioned defects, the embodiments of this disclosure provide a dovetail vise fixture, which solves the technical problem in the prior art that when processing workpieces of different sizes or shapes, a lot of time is often required to change the jaws and readjust the fixture parameters, which is cumbersome, time-consuming and labor-intensive, resulting in prolonged equipment downtime and a significant reduction in production efficiency.

[0004] According to one aspect, at least one embodiment of this disclosure provides a dovetail vise clamp, comprising: A machining base, wherein a force-bearing chuck is provided on the machining base; An adjustable clamping assembly is disposed on the upper end face of the machining base; A drive screwing assembly is mounted on the machining base; The adjusting clamping assembly includes a mounting plate disposed on the upper end face of the force-bearing clamping plate. A positioning groove is formed on the mounting plate, and a positioning plate is inserted into the positioning groove. A clamping dovetail groove is formed on the inner side wall of the positioning plate, and a clamping plate is disposed inside the clamping dovetail groove. A drive groove is formed on the side wall of the force-bearing clamping plate, and a drive shaft is disposed inside the drive groove. A linkage frame is connected to the end of the drive shaft, and a drive plate is disposed at the upper end of the linkage frame. The drive plate corresponds to the position of the positioning plate. A drive dovetail groove is formed on the drive plate, and a drive fixing plate is disposed inside the drive dovetail groove.

[0005] As a further technical solution, the upper end face of the force-bearing clamp is provided with connecting bolt holes, and the force-bearing clamp and the mounting plate are fixedly connected through the connecting bolt holes.

[0006] As a further technical solution, the drive screwing assembly includes a drive cavity, which is opened inside the drive shaft. A screwing shaft is disposed inside the drive cavity, and the screwing shaft is threadedly connected to the drive cavity. One end of the screwing shaft is provided with a plug-in shaft, which extends out of the drive cavity.

[0007] As a further technical solution, one end of the screwing shaft extends out of the drive cavity, and the side wall of the screwing shaft has a drive hole, which is hexagonal in shape.

[0008] As a further technical solution, one end of the plug shaft is provided with a limiting shaft, and a limiting groove is opened inside the drive groove, and the limiting shaft is inserted into the limiting groove.

[0009] As a further technical solution, the upper end face of the force-bearing chuck has several bolt fixing holes, and the force-bearing chuck and the machining base are fixedly connected through the bolt fixing holes.

[0010] As a further technical solution, the inner sidewall of the drive groove is provided with a limiting strip, and the sidewall of the linkage frame is provided with a limiting groove, with the limiting strip embedded inside the limiting groove.

[0011] As a further technical solution, a fixed reinforcing rib is provided between the linkage frame and the drive disk.

[0012] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the dovetail groove structure has good self-locking properties and can provide a large clamping force, making the workpiece less prone to loosening after being clamped. For example, a quick-change dovetail groove fixture that uses a dovetail groove connection between the workpiece and the clamping seat can effectively prevent the workpiece from shifting during processing and ensure processing stability. The dovetail groove vise fixture can accurately position the workpiece through the cooperation of the dovetail groove. The dovetail groove tooling fixture uses a specific method to position the two sides of the workpiece that are not clamped, which can effectively improve the positioning accuracy of the workpiece and thus improve the processing accuracy.

[0015] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0020] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] like Figures 1-3 As shown, a dovetail vise clamp of this disclosure includes: A machining base 1, on which a force-bearing chuck 2 is provided; Adjusting clamping assembly 3, which is set on the upper end face of machining base 1; Drive screwing assembly 4, which is mounted on machining base 1; The adjusting clamping assembly 3 includes a mounting plate 3-1, which is located on the upper surface of the force-bearing clamping plate 2. The mounting plate 3-1 has a positioning groove 3-2, and a positioning plate 3-3 is inserted into the positioning groove 3-2. The inner side wall of the positioning plate 3-3 has a clamping dovetail groove 3-4, and a clamping plate 3-5 is located inside the clamping dovetail groove 3-4. The side wall of the force-bearing clamping plate 2 has a driving groove 3-6, and a driving shaft 3-7 is located inside the driving groove 3-6. The end of the driving shaft 3-7 is connected to a linkage frame 3-8, and a driving plate 3-9 is located at the upper end of the linkage frame 3-8. The driving plate 3-9 corresponds to the position of the positioning plate 3-3. The driving plate 3-9 has a driving dovetail groove 3-10, and a driving fixing plate 3-11 is located inside the driving dovetail groove 3-10.

[0022] The drive screwing assembly 4 includes a drive cavity 4-1, which is located inside the drive shaft 3-7. A screwing shaft 4-2 is provided inside the drive cavity 4-1. The screwing shaft 4-2 is threadedly connected to the drive cavity 4-1. One end of the screwing shaft 4-2 is provided with a plug shaft 4-3, which extends out of the drive cavity 4-1.

[0023] In some examples, the force-bearing chuck 2 is placed at a designated position on the machining base 1, aligning the bolt fixing holes 5 on the force-bearing chuck 2 with the corresponding mounting holes on the machining base 1. The positioning plate 3-3 is inserted into the positioning groove 3-2 of the mounting plate 3-1, ensuring that the positioning plate 3-3 can slide freely and fit tightly within the positioning groove 3-2 without significant shaking. The clamping dovetail groove 3-4 on the inner side wall of the positioning plate 3-3 should face a suitable direction to facilitate the subsequent installation of the clamping plate 3-5 and the clamping operation of the workpiece. The clamping plate 3-5 is installed inside the clamping dovetail groove 3-4. The appropriate clamping plate 3-5 is selected according to the actual size and shape of the workpiece being processed. During installation, the fitting accuracy between the clamping plate 3-5 and the clamping dovetail groove 3-4 must be ensured to guarantee that the clamping plate 3-5 can move flexibly within the dovetail groove and provide sufficient clamping force when clamping the workpiece.

[0024] Install the drive shaft 3-7 in the drive groove 3-6 on the side wall of the force-bearing chuck 2 to ensure that the drive shaft 3-7 can rotate freely in the drive groove 3-6. The end of the drive shaft 3-7 is connected to the linkage 3-8. The connection method can be key connection or other reliable connection method to ensure that the drive shaft 3-7 can effectively drive the linkage 3-8 to move when it rotates.

[0025] Install the drive plate 3-9 on the upper end of the linkage frame 3-8, so that the position of the drive plate 3-9 corresponds precisely with that of the positioning plate 3-3. The drive dovetail groove 3-10 on the drive plate 3-9 should cooperate with the relevant structure of the positioning plate 3-3 for subsequent driving of the positioning plate 3-3 and the clamping plate 3-5. After installation, manually rotate the drive shaft 3-7 to check whether the movement of the linkage frame 3-8 and the drive plate 3-9 is smooth and whether there is any jamming or interference. If there is any problem, adjust the installation position of each component or make necessary repairs in time.

[0026] Insert the screw shaft 4-2 into the drive cavity 4-1 inside the drive shaft 3-7. Since the screw shaft 4-2 and the drive cavity 4-1 are connected by a thread, pay attention to the direction of rotation of the screw shaft 4-2 when inserting it to ensure that it can be screwed in smoothly. One end of the screw shaft 4-2 is provided with a plug shaft 4-3. During the installation process, ensure that the plug shaft 4-3 can extend smoothly out of the drive cavity 4-1.

[0027] like Figures 1-3 As shown in the figure, this embodiment proposes that the upper end face of the force-bearing clamp 2 is provided with connecting bolt holes 3-12, and the force-bearing clamp 2 and the mounting plate 3-1 are fixedly connected through the connecting bolt holes 3-12.

[0028] In some examples, after confirming that the positioning groove 3-2 of the mounting plate 3-1 corresponds correctly with the connecting bolt hole 3-12 of the force-bearing clamp 2, the mounting plate 3-1 is placed on the upper surface of the force-bearing clamp 2, the connecting bolt hole 3-12 is aligned, and the connecting bolt is passed through the connecting bolt hole 3-12 to fix the mounting plate 3-1 and the force-bearing clamp 2 together. Similarly, when tightening the connecting bolt, the diagonal tightening principle should be followed to ensure that the mounting plate 3-1 is installed stably.

[0029] For example, such as Figure 3 As shown, one end of the screw shaft 4-2 extends out of the drive cavity 4-1, and the side wall of the screw shaft 4-2 has a drive hole 4-4, which is hexagonal in shape.

[0030] In some examples, one end of the screwing shaft 4-2 extends out of the drive cavity 4-1, and its side wall has a drive hole 4-4. The drive hole 4-4 has a hexagonal structure. In actual operation, a matching tool such as a hexagonal wrench can be inserted into the drive hole 4-4, and the screwing shaft 4-2 can be rotated by rotating the wrench. Since the screwing shaft 4-2 is threadedly connected to the drive cavity 4-1, the rotation of the screwing shaft 4-2 will cause it to move axially within the drive cavity 4-1. This, in turn, drives the drive disk 3-9 to move through components such as the plug-in shaft 4-3, drive shaft 3-7, and linkage frame 3-8, ultimately achieving the drive adjustment of the positioning disk 3-3 and the clamping disk 3-5 to adapt to the clamping requirements of different workpieces.

[0031] For example, such as Figure 2As shown, a limiting shaft 4-5 is provided at one end of the insertion shaft 4-3, and a limiting groove 4-6 is opened inside the drive groove 3-6, and the limiting shaft 4-5 is inserted into the limiting groove 4-6.

[0032] In some examples, a limiting shaft 4-5 is installed at one end of the plug-in shaft 4-3. At the same time, a limiting groove 4-6 is opened at a corresponding position inside the drive groove 3-6. The limiting shaft 4-5 is inserted into the limiting groove 4-6. In this way, when the screwing shaft 4-2 rotates, the limiting shaft 4-5 moves within the limiting groove 4-6, which can limit the axial displacement of the drive shaft 3-7, ensure the stable rotation of the drive shaft 3-7, and at the same time ensure the normal operation of the drive screwing assembly 4.

[0033] For example, such as Figure 1 As shown, the upper end face of the force-bearing chuck 2 has several bolt fixing holes 5, and the force-bearing chuck 2 and the machining base 1 are fixedly connected through the bolt fixing holes 5.

[0034] In some examples, using suitable bolts, the force-bearing chuck 2 is tightly fixed to the machining base 1 through the bolt fixing holes 5. When tightening the bolts, a diagonal tightening method should be used to gradually and evenly apply torque to ensure that the force-bearing chuck 2 is installed firmly and in a horizontal state, so as to prevent shaking or displacement during subsequent processing due to improper installation.

[0035] For example, such as Figure 2 As shown, the inner sidewall of the drive groove 3-6 is provided with a limit strip 6, and the sidewall of the linkage frame 3-8 is provided with a limit groove 7, with the limit strip 6 embedded inside the limit groove 7.

[0036] In some examples, a limiting strip 6 is installed on the inner side wall of the drive groove 3-6, and a limiting groove 7 is machined on the side wall of the linkage 3-8. During installation, the limiting strip 6 is embedded inside the limiting groove 7, and the fit between the two is ensured. This allows the linkage 3-8 to slide smoothly in the drive groove 3-6 along the direction of the limiting strip 6, and effectively limits the shaking of the linkage 3-8 during the movement, ensuring the stability and accuracy of the drive process.

[0037] For example, such as Figure 3 As shown, a fixing reinforcing rib 8 is provided between the linkage frame 3-8 and the drive disk 3-9.

[0038] In some examples, a fixing reinforcing rib 8 is installed between the linkage frame 3-8 and the drive disk 3-9. The function of the fixing reinforcing rib 8 is to enhance the connection strength between the linkage frame 3-8 and the drive disk 3-9 and improve the rigidity of the overall structure. When installing the fixing reinforcing rib 8, it should be ensured that its connection with the linkage frame 3-8 and the drive disk 3-9 is firm. Reliable methods such as welding and bolt connection can be used for fixing.

[0039] In use, the dovetail vise begins to operate by inputting power to the drive screwing assembly 4, which is the core of the entire vise. The operator uses a hexagonal wrench or other compatible tool to insert into the hexagonal drive hole 4-4 on the side wall of the screwing shaft 4-2. By manually rotating the wrench, external force is transmitted to the screwing shaft 4-2, causing it to rotate. Since the screwing shaft 4-2 is threadedly connected to the drive cavity 4-1 inside the drive shaft 3-7, and the insertion shaft 4-3 at one end of the screwing shaft 4-2 is embedded in the limiting groove 4-6 of the drive groove 3-6 via the limiting shaft 4-5, the movement of the limiting shaft 4-5 within the limiting groove 4-6 restricts the axial rotation of the screwing shaft 4-2. Therefore, the rotational motion of the screwing shaft 4-2 is converted into axial linear motion along the axis of the drive cavity 4-1, providing initial power for subsequent clamping actions.

[0040] The axial linear motion of the screw shaft 4-2 is transmitted to the drive shaft 3-7 through the plug-in shaft 4-3, causing the drive shaft 3-7 to move axially synchronously within the drive groove 3-6 on the side wall of the force-bearing chuck 2. The end of the drive shaft 3-7 is reliably fixed to the linkage frame 3-8 using a key connection or other reliable methods. The axial movement of the drive shaft 3-7 directly pulls the linkage frame 3-8 to move along the drive groove 3-6. During this process, the limiting strip 6 on the inner side wall of the drive groove 3-6 is embedded in the limiting slide groove 7 on the side wall of the linkage frame 3-8, ensuring that the linkage frame 3-8 can only make stable linear motion along the direction of the limiting strip 6, avoiding lateral deviation or swaying. The upper end of the linkage frame 3-8 is fixedly connected to the drive disk 3-9, and a fixed reinforcing rib 8 is provided between the two to enhance the structural rigidity. Therefore, the linear motion of the linkage frame 3-8 is synchronously transmitted to the drive disk 3-9, causing the drive disk 3-9 to move in the specified direction, completing the conversion and transmission of "rotational power → axial power → linear power".

[0041] The movement of the drive disk 3-9 directly acts on the positioning disk 3-3. Due to the precise fit between the drive dovetail groove 3-10 on the drive disk 3-9 and the positioning disk 3-3, the drive disk 3-9 pushes the positioning disk 3-3 to slide within the positioning groove 3-2 of the mounting disk 3-1. The inner wall of the positioning disk 3-3 is provided with a clamping dovetail groove 3-4, and the clamping disk 3-5 is installed within the clamping dovetail groove 3-4. The sliding of the positioning disk 3-3 drives the clamping disk 3-5 to move synchronously. The dovetail groove structure has the characteristics of strong self-locking and high fitting accuracy. When the clamping disk 3-5 moves within the clamping dovetail groove 3-4, it can closely fit the inner wall of the dovetail groove to avoid loosening or displacement. As the clamping disk 3-5 moves, the distance between it and the fixed structure on the other side of the fixture (or another set of clamping components symmetrically arranged) gradually decreases until it is in close contact with the workpiece surface. By applying clamping force, the workpiece is firmly fixed in the designated position, realizing the clamping and positioning of the workpiece to meet the needs of subsequent machining.

[0042] Throughout the entire operation, multiple structures work together to ensure the stability and reliability of the fixture. First, the machining base 1 and the force-bearing chuck 2 are tightly connected by bolt fixing holes 5 and connecting bolts, providing a stable foundation support for the entire fixture and preventing the base from shaking during machining. Second, the cooperation between the limiting strip 6 and the limiting groove 7 restricts the movement direction of the linkage frame 3-8, ensuring a stable power transmission path. Third, the fixing reinforcing rib 8 enhances the connection rigidity between the linkage frame 3-8 and the drive plate 3-9, preventing deformation of both under stress. Finally, the cooperation between the limiting shaft 4-5 and the limiting groove 4-6 restricts the axial displacement of the drive shaft 3-7, ensuring the power transmission efficiency of the drive screwing assembly 4. These structures work together to ensure that the fixture remains stable when clamping the workpiece, preventing machining accuracy from being affected by structural loosening or deformation.
