Description

Technical Field

[0001] The utility model relates to a co-located multi-piece processing positioning device, in particular to the technical field of efficient processing positioning of multiple shell parts. Background Art

[0002] Square shell parts are common machined products. Technicians usually use transmission vises for positioning, which has the following three technical problems:

[0003] 1) Transmission vises are mostly fixed on the operating table, and their posture and angle cannot be adjusted. When processing different surfaces of parts, the vise needs to be disassembled and assembled multiple times, resulting in low processing efficiency and poor processing consistency.

[0004] 2) Traditional vises can only position one workpiece at a time. When using a machine tool to process multiple parts, each workpiece can only be disassembled, assembled, and positioned one by one. It is impossible to disassemble and assemble multiple products at a time.

[0005] 3) Traditional vises often use bosses or non-planar jaws, which makes it difficult to position the workpiece.

[0006] How to design a co-located multi-piece processing positioning device to solve the above technical problems has long troubled technicians in this field. Utility Model Content

[0007] In view of this, the utility model proposes a co-positioned multi-piece processing positioning device, which can clamp four shell products at the same time and coaxially turn to process multiple products at one time, thereby ensuring the consistency of the products and related quality requirements, saving operating steps and clamping times, and improving equipment utilization and production efficiency.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

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

[0029] like Figures 1 to 7 As shown, the same-position multi-piece processing and positioning device includes a square T-slot base 1 and a plurality of vises 2. In the figure, the square T-slot base 1 is composed of a plurality of vertically stacked square T-slot blocks 101 and a base 102. Four weight-reducing through holes 103 are symmetrically opened inside the square T-slot base 1. The sides of the square T-slot blocks 101 are each provided with a cross-shaped side T-slot 104. The side T-slot 104 is used to install the T-block 105 and the positioning key 106. A rotating shaft seat 107 is provided in the center of the base 102. A cross-shaped inner T-slot 108 is provided on the inner surface of the base 102. A plurality of connecting screws 109 are provided around the base 102.

[0030] Specifically, the square T-slot blocks 101 can be extended through positioning keys 106, the height of the square T-slot base can be flexibly adjusted, and the shaft seat 107 is used to connect the shaft, which can drive the entire positioning device to rotate to adjust the angle posture.

[0031] In the figure, four vises are symmetrically mounted on the four sides of the square T-slot base. The vises are detachably fixed in the T-slot by means of T-blocks, positioning keys, etc., and the number of vises can be flexibly adjusted. Specifically, the vise 2 consists of a track 201, and a fixed vise 202 and a movable vise 203 on the track 201; the vise 2 is used to position the housing part 3. Among them: the front of the track 201 of the vise 2 is provided with a slide groove 204, and the back of the track 201 is provided with a positioning groove 205 at the position corresponding to the side T-slot 104. The bottom of the slide groove 204 is equidistantly provided with a plurality of positioning holes 206, and positioning screws 207 are installed in the positioning holes 206 on both sides. The ends of the positioning screws 207 pass through the track 201 and are connected to the threaded holes of the T-block 105. The fixed vise 202 is fixed to one end of the track 201 by a plurality of fixed screws 208. A sliding block 209 is connected to one side of the movable vise 203, and the sliding block 209 is movably installed in the slide groove 204. Limiting threaded holes 210 are symmetrically and inwardly inclined on both sides of the sliding block 209. Ball cavities are provided at the inner ends of the two limiting threaded holes 210. A limiting screw rod 211 is installed in the limiting threaded hole 210, and a limiting ball 212 is installed inside the ball cavity. The top of the limiting ball 212 contacts the bottom of the limiting screw rod 211, and the lower part of the limiting ball 212 is installed in the corresponding positioning hole 206.

[0032] It should be noted that by adjusting the height of the limit screw, the top activity space of the limit ball can be changed. When the activity space is large enough, the limit ball can roll out of the positioning hole. At this time, the position of the dynamic vise can be flexibly adjusted. When the position is determined, the limit ball is allowed to roll into another corresponding positioning hole, and the limit screw is tightened to complete the limiting work. In addition, a compression spring can be arranged between the limit screw and the limit ball. The compression spring is arranged at the bottom of the limit threaded hole and directly contacts the limit ball. At this time, the damped movement of the dynamic vise can be realized. When the limit screw is tightened, the compression spring is compressed and greater pressure is added to the limit ball. At this time, the corresponding adjustment resistance will also increase.

[0033] In this embodiment, both the fixed vise 202 and the movable vise 203 have flat jaws. Figure 5 and Figure 6 As shown, the material that the flat jaws contact with the workpiece can be an elastic material, and the contact surface is provided with anti-slip textures.

[0034] In actual application, first calibrate the center of the square T-slot base to be consistent with the rotation center of the worktable, and fasten it to the worktable. Secondly, use the positioning key to position the vise at the center and horizontal position of the square base. At this time, the X and Z directions of the vise are determined, and the screws and T-blocks are tightened at the same time to fix the vise and the square base. In addition, check whether the positioning planes of the four sets of precision vises are consistent in the X-axis, Y-axis, and Z-axis. Finally, fit the two mutually perpendicular planes of the shell product with the X and Y positioning surfaces of the vise, tighten the vise screw, and thus clamp the product. Then, the worktable can be rotated 90° in turn, and the same processing operation can be performed on each identical product. Compared with the existing vise and clamp arm fixing method, this device can clamp four shell products at the same time, and coaxial steering can process multiple products at one time, ensuring the consistency of the products and related quality requirements, saving operation steps and clamping times, and improving equipment utilization and production efficiency.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
