Description

Technical Field

[0001] The invention relates to the field of mechanical tooling fixtures, in particular to a manual vise for clamping a traveling welding tool. Background Art

[0002] In the manufacturing industry, welding is the most important splicing process, and it has high requirements for the stability and reliability of welding tools (fixtures), especially the production method in which the tooling flows along the production line with the workpiece. The tooling can be called accompanying tooling. In the field of robotic automated welding tooling, the clamping mechanism usually uses a cylinder or a hydraulic cylinder as the source of the clamping force. The accompanying tooling needs to have a quick-insert mechanism with an air source and an electrical signal source, which is complex and expensive. In the field of manual welding tooling, the clamping mechanism is usually various forms of manual quick clamps as the source of the clamping force. At present, in the field of manual welding tooling, the research content of accompanying tooling mainly focuses on the two directions of compact structure and convenient manual operation.

[0003] In the research direction of compact structure, since the welding tooling itself must have a certain strength and rigidity to resist the welding deformation of the workpiece during welding, the improvement of the tooling strength and rigidity is also accompanied by the strengthening of the tooling structure and the increase of the overall weight of the tooling. These two problems are interrelated. If we study the improvement of the material of the tooling and choose light but high-strength materials as the manufacturing materials of the accompanying tooling, the cost will increase, the input-output ratio will increase, and it will be difficult to promote the market.

[0004] In the research direction of convenient manual operation, workers (operators) need to perform correct production operations according to the operation instructions during welding production operations. Too many operation steps will increase labor costs and reduce efficiency on the one hand, and increase the training costs for new employees on the other hand. Summary of the invention

[0005] In view of the above problems, the present invention provides a manual vise clamping accompanying welding tool, which utilizes the action principle of the vise clamping mechanism used in vise work, realizes a compact structure, self-locking after clamping, stable and reliable clamping force, and achieves the purpose of rapid positioning and clamping of workpieces by manual operation.

[0006] The present invention adopts the following technical solutions to achieve the above purpose:

[0007] A manual vise clamping accompanying welding tool comprises a movable positioning angle seat, a fixed positioning angle seat, an accompanying tool body, and a slide plate, wherein the clamping surfaces of the movable positioning angle seat and the fixed positioning angle seat are arranged back to back, the fixed positioning angle seat is fixed on the accompanying tool body, the movable positioning angle seat is fixed on the slide plate, the slide plate is arranged on the accompanying tool body and is movably connected with the accompanying tool body, a threaded sleeve mounting seat is arranged between the movable positioning angle seat and the fixed positioning angle seat, a threaded sleeve pressing plate is vertically arranged on the threaded sleeve mounting seat, a threaded sleeve is penetrated on the threaded sleeve pressing plate, a connecting block is arranged on the slide plate, a screw is arranged on the connecting block, one end of the screw is connected to the connecting block, and the other end is threadedly connected to the threaded sleeve, and a spiral clamp is arranged at both ends of the relative movable positioning angle seat and the fixed positioning angle seat. Such a structure is compact, the clamping force is stable and reliable, and rapid positioning and clamping of workpieces by manual operation can be realized.

[0008] Preferably, the slide plate is provided with clamping stroke limit blocks on both sides of the movable positioning angle seat, and the slide plate is provided with fixed blocks on both sides of the accompanying tooling body. Such provision of fixed blocks not only provides an installation position for the guide plate, limits the vertical movement of the slide plate, and facilitates the horizontal sliding of the slide plate on the tooling body, but also the fixed blocks serve as a limit for the clamping stroke limit blocks. This not only limits the horizontal sliding stroke of the slide plate, but also indirectly limits the clamping stroke and positioning of the movable positioning angle seat.

[0009] Preferably, a guide plate is provided on the contact surface between the fixed block and the slide plate, and graphite lubrication is used between the guide plate and the slide plate. Such a setting can make the slide plate slide smoothly without obstruction, and at the same time make the slide plate movable positioning precision high.

[0010] Preferably, at both ends of the movable positioning angle seat and the fixed positioning angle seat, at least three screw clamps are arranged on each end, so as to form a stable clamping surface for the workpiece.

[0011] Preferably, the spiral clamp is threadedly connected to its base support. Such an arrangement can facilitate the staff to adjust the clamping degree of the spiral clamp on the workpiece.

[0012] Preferably, the screw clamp has at least two horizontal settings and at least one vertical setting. Such a setting can better fix and support the workpiece and bear force in the horizontal and vertical directions.

[0013] Preferably, the threaded sleeve has a through hole, so that the staff can use auxiliary tools, such as an iron rod or a lever tool such as an Allen wrench, to insert it into the through hole on the threaded sleeve, rotate the threaded sleeve, and adjust the slide plate through the threaded connection between the threaded sleeve and the screw rod, so as to achieve the clamping and loosening of the movable positioning angle seat and the workpiece.

[0014] The beneficial effects of the present invention are:

[0015] 1. The manual vise provided by the present invention mainly adopts the self-locking function of the threaded pair, combined with the advantages of reliable and stable vise clamping mechanism, large clamping force, light overall weight of the tooling, convenient maintenance, low cost, etc., which greatly improves the practicality of the welding tooling;

[0016] 2. The manual vise provided by the present invention for clamping the accompanying welding tool has the significant advantages of compact structure, small space occupation, reliable and stable clamping force on the workpiece, and simple manual operation compared with the traditional manual quick clamp mechanism;

[0017] 3. The manual vise provided by the present invention for clamping the accompanying welding tool has a certain flexibility, and the travel limit block can be replaced as needed to adjust the clamping and opening travel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following is combined with Figures 1 to 4 The present invention is described in detail with specific embodiments.

[0024] like Figure 1As shown, it is an embodiment of the present invention, providing a manual vise to clamp the accompanying welding tool, including a movable positioning angle seat 2, a fixed positioning angle seat 5, an accompanying tool body 1, and a slide plate 8. The clamping surfaces of the movable positioning angle seat 2 and the fixed positioning angle seat 5 are arranged back to back, the fixed positioning angle seat 5 is fixed on the accompanying tool body 1, the movable positioning angle seat 2 is fixed on the slide plate 8, the slide plate 8 is arranged on the accompanying tool body 1, and is movably connected with the accompanying tool body 1, a threaded sleeve mounting seat 6 is arranged between the movable positioning angle seat 2 and the fixed positioning angle seat 5, a threaded sleeve pressing plate 10 is vertically arranged on the threaded sleeve mounting seat 6, a threaded sleeve 4 is penetrated on the threaded sleeve pressing plate 10, a connecting block 12 is arranged on the slide plate 8, a screw 3 is arranged on the connecting block 12, one end of the screw 3 is connected to the connecting block 12, and the other end thereof is threadedly connected to the threaded sleeve 4, and spiral clamps 9 are arranged at both ends of the relative movable positioning angle seat 2 and the fixed positioning angle seat 5.

[0025] On the welding tool of the present invention, a fixed positioning angle seat 5 is used as the positioning reference of the workpiece (i.e., the fixed clamping surface of the vise mechanism), and a movable positioning angle seat 2 is installed on a slidable slide 8 to form a movable clamping surface similar to a vise clamping mechanism. A screw rod 3 with an external thread is installed on the slide 8, one end of the screw rod 3 and the slide 8 are fastened and installed by bolts, and the other end is screwed into a threaded sleeve 4 with an internal thread. One end of the threaded sleeve 4 is limited on the fixed threaded sleeve mounting seat 6 through a U-shaped slot, and the threaded sleeve 4 is connected with the external thread of the screw rod 3 through the internal thread. The threaded sleeve 4 can rotate around the screw rod 3, so that the fine-tuning movement of the slide 8 can be achieved by rotating the threaded sleeve 4, so that the movable positioning angle seat 2 installed on the slide 8 can open and clamp the workpiece 15. At the same time, the threaded connection has a self-locking function to ensure that the sliding part will not cause the clamping failure of the mechanism of the present invention due to the reaction force of the workpiece clamping.

[0026] Furthermore, on the slide plate 8, the two sides of the movable positioning angle seat 2 are provided with clamping stroke limit blocks 7, and on the accompanying tool body 1, the two sides of the slide plate 8 are provided with fixed blocks 13. The setting of the fixed blocks 13 not only provides the installation position of the guide plate 11, limits the vertical movement of the slide plate 8, and facilitates the horizontal sliding of the slide plate 8 on the accompanying tool body 1, but also the fixed blocks 13 also serve as the limit for the clamping stroke limit blocks 7. It not only limits the horizontal sliding stroke of the slide plate 8, but also indirectly limits the clamping stroke and positioning of the movable positioning angle seat 2.

[0027] Furthermore, the contact surface between the fixed block 13 and the slide plate 8 is provided with a guide plate 11, and graphite lubrication is used between the guide plate 11 and the slide plate 8. Such a setting can make the slide plate 8 slide smoothly without obstruction, and at the same time make the slide plate active positioning precision high.

[0028] Furthermore, at both ends of the movable positioning angle seat 2 and the fixed positioning angle seat 5, at each end, more than three screw clamps 9 are provided, so that a stable clamping surface can be formed for the workpiece.

[0029] Furthermore, the screw clamp 9 is threadedly connected to the base support, so that the worker can adjust the clamping degree of the workpiece by the screw clamp.

[0030] Furthermore, the spiral clamps 9 have at least two horizontal settings and at least one vertical setting. Such a setting can better fix and support the workpiece and bear force in the horizontal and vertical directions.

[0031] Furthermore, the threaded sleeve 4 has a through hole, which allows the staff to use auxiliary tools, such as an iron rod or a lever tool such as an Allen wrench, to insert into the through hole on the threaded sleeve 4, rotate the threaded sleeve 4, and adjust the slide plate 8 through the threaded connection between the threaded sleeve 4 and the screw rod 3, so as to achieve the clamping and separation of the movable positioning angle seat 2 and the workpiece.

[0032] like Figure 1-4 As shown, when welding the workpiece 15, the workpiece 15 is a beam chassis, which is fixed in the horizontal direction by a fixed positioning angle seat 5 and two horizontally arranged screw clamps 9, and one of the vertical directions is provided with a screw clamp 9 to limit and fix the beam in the vertical direction. The operator rotates the threaded sleeve 4 to clamp the other beam together with the clamping surface of the movable positioning angle seat 2 of the mechanism of the present invention and the screw clamp 9. When the travel limit block 7 hits the fixed block 13 on the accompanying tooling body 1, it indicates that the clamping is in place.

[0033] The manual vise clamping accompanying welding tool provided by the present invention has a compact structure, simple manual operation, reliable clamping force, and has neither complicated actions and operation processes nor complex and expensive control components and auxiliary systems integrated in automated tooling. The present invention has certain technical advantages in accompanying tooling where the working space is limited and conventional manual quick clamps cannot be installed.
