Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-2, the utility model provides a technical solution: the utility model provides a car parts processing is with positioner that positioning accuracy is high, includes a frock platform 1, and a draw-in groove 2 has been seted up to the central authorities at frock platform 1 top, and the top of this draw-in groove 2 is provided with solid fixed ring 3, and gu fixed ring 3's internal diameter equals with the diameter of draw-in groove 2.

As shown in fig. 3, a plurality of auxiliary clamps 4 are arranged in the clamping groove 2, rubber anti-slip pads 21 are attached to the inner side walls of the auxiliary clamps 4, the rubber anti-slip pads 21 are arranged, the anti-slip purpose is achieved, one sides of the auxiliary clamps 4 are connected with the inner side walls of the clamping groove 2 through springs 5, and the auxiliary clamps 4 are connected end to end through telescopic spring ropes 6 (it needs to be explained that when the springs 5 and the spring ropes 6 are completely loosened, the minimum clamping radius of the auxiliary clamps 4 is obtained at the moment, and therefore the bottom radius of the machined part is generally not smaller than the minimum clamping radius).

As shown in fig. 1-2, an annular groove 7 is formed in the top of the tooling table 1, the annular groove 7 is located outside the fixing ring 3, an annular slide rail 8 is fixedly arranged in the annular groove 7, an arc-shaped connecting rail 9 is detachably clamped at a notch of the annular slide rail 8, and the inner diameter and the outer diameter of the annular slide rail 8 and the outer diameter of the arc-shaped connecting rail 9 are equal to each other, so that seamless butt joint is realized.

As shown in fig. 1 to 4, a first notch 16 and a second notch 17 are respectively formed in a side surface of the arc-shaped connecting rail 9, the first notch 16 is communicated with the second notch 17, a plug 18 is slidably mounted in the second notch 17, one side of the plug 18 is connected with a side wall of the second notch 17 through a telescopic spring 19, a push handle 20 is slidably mounted in the first notch 16, the bottom of the push handle 20 is connected with the top of the plug 18, one end of the plug 18 is clamped into a notch at the notch of the annular slide rail 8, and the top of the plug 18 is not higher than the top of the first notch 16, so as to prevent interference with sliding of the first slide carriage 10.

As shown in fig. 1-2, a plurality of first sliding seats 10 are slidably mounted on an annular sliding rail 8, the first sliding seats 10 are as wide as an annular groove 7, a side wall of each of the first sliding seats 10 is fixedly connected with a linear rail 11, the bottom of the linear rail 11 is in contact with the top of a tooling table 1, a second sliding seat 12 is slidably mounted on the linear rail 11, the top of the second sliding seat 12 is fixedly connected with a fixing baffle 13, a clamping bolt 14 is threadedly connected on the fixing baffle 13, the clamping bolt 14 is located above a fixing ring 3, lug plates 22 are integrally formed on two sides of the second sliding seat 12, a positioning bolt 23 is threadedly connected on the lug plates 22, and the top of the first sliding seat 10 is locked with the top of the annular sliding rail 8 through a locking bolt 15.

During the use, at first place the machined part in draw-in groove 2 to make the machined part card in the inboard of several supplementary clamping 4, supplementary clamping 4 passes through 6 end to end connections of spring rope, consequently through the flexible effect with the help of spring rope 6, can make supplementary clamping 4 open the big opening size of difference, thereby can press from both sides the machined part of tight different thicknesses.

Because the surface of the workpiece with the special-shaped part is irregular, in order to find a part which is relatively convenient to clamp, the first sliding seat 10 can be slid on the annular sliding rail 8, so that the clamping bolt 14 is rotated to the optimal clamping position, then the locking bolt 15 is rotated to fix the first sliding seat 10, then the second sliding seat 12 is slid to drive the clamping bolt 14 to be close to the workpiece, the position of the second sliding seat 12 is fixed through the positioning bolt 23, and finally the clamping bolt 14 is rotated to clamp the workpiece, and the clamping bolt 14 is located at the optimal clamping position, so that the positioning is more accurate and firmer.

Furthermore, different workpieces have different sizes and different volumes, so that the number of required positioning mechanisms is different, and for the workpieces with regular shapes and small volumes, if the positioning mechanisms are too many, the processing is influenced on the contrary, and for the workpieces with complex structures and large volumes, if the positioning mechanisms are too few, the positioning precision is influenced on the contrary.

In order to increase or decrease the number of the positioning mechanisms on the annular slide rail 8, we have provided the detachable arc-shaped connecting rail 9, as long as the arc-shaped connecting rail 9 is detached, the positioning mechanisms can be increased or decreased through the notch of the annular slide rail 8, here, taking the detachment of the arc-shaped connecting rail 9 as an example, as shown in fig. 4, first pushing two push handles 20 (pushing towards the direction of approaching each other) to drive the plug 18 to move, so that the plug 18 leaves the notch of the annular slide rail 8, thereby releasing the constraint, then directly pulling out the arc-shaped connecting rail 9, finally taking out the first slide 10 together with the positioning mechanisms such as the linear rail 11 and the clamping bolt 14 from the notch, or mounting the first slide 10 together with the positioning mechanisms such as the linear rail 11 and the clamping bolt 14 on the annular slide rail 8 through the notch, and then mounting and resetting the arc-shaped connecting rail 9, and the arc-shaped connecting rail 9 and the annular sliding rail 8 are clamped tightly through the plug 18, so that a complete closed-loop rail is formed and is convenient to slide.

Therefore, the positioning accuracy can be improved by adjusting the orientation and the number of the positioning mechanisms.

In summary, the positioning device with high positioning precision for processing the automobile parts can freely adjust the direction of the positioning mechanism by arranging the positioning mechanism capable of freely sliding, thereby greatly improving the flexibility of the positioning mechanism, adjusting the position of the positioning mechanism aiming at different machined parts, and clamping the machined parts at the optimal angle, thereby ensuring accurate positioning and firm clamping.
