Description

Technical Field

[0001] This utility model belongs to the field of machining and trimming tooling technology, specifically relating to a quick positioning and trimming tooling for side-support rod type forging blanks. Background Technology

[0002] Some U-shaped groove structures exist in the blanks of side-support rod forgings. The holes in the U-shaped grooves are pre-cut on a waterjet cutting machine, and the remaining part of the U-shaped groove is removed on a saw. The shortcomings of the existing technology are that the edges cut manually by the operator on the saw are not straight, easily deviating from the intended shape, and the sawing depth is difficult to control, easily resulting in overcutting and product scrapping, and the processing efficiency is extremely low. Therefore, a new and simple edge-cutting fixture is urgently needed for the processing of U-shaped grooves. Utility Model Content

[0003] In view of this, and in response to the above-mentioned problems, this patent proposes a quick positioning and trimming tool for side-support rod forging blanks. It has a simple structure and is easy to operate, and is especially suitable for processing forgings with U-shaped grooves.

[0004] According to one aspect of the present invention, a quick positioning and trimming fixture for a side-support rod forging blank is provided, comprising: a profile fixture 3, a cylindrical pin 4, a profile pad 6, a fixture pad 8, a positioning pin 9, and a stop pin 10. The positioning pin 9 and the stop pin 10 are disposed on the surface of the fixture pad 8. The profile fixture 3 is mounted on the surface of the fixture pad 8 and can slide along the positioning pin 9. The positioning pin 9 is used to constrain the sliding direction of the fixture pad 8. The stop pin 10 is disposed at one end of the fixture pad 8 and is used to constrain the sliding termination position of the profile fixture 3. The profile fixture 3 is provided with the profile pad 6 and the cylindrical pin 4 for positioning the side-support rod forging blank. The upper surface of the profile pad 6 contacts and matches the outer surface of the side-support rod forging blank, and the cylindrical pin 4 is used to penetrate the positioning hole of the side-support rod forging blank.

[0005] Optionally, the profile tooling 3 also includes a push handle 5 for external force to push the profile tooling 3 to slide.

[0006] Optionally, the locating pin 9 is used to constrain the tooling pad 8 to slide linearly.

[0007] Optionally, the profile pad 6 is made of plastic.

[0008] Optionally, a U-shaped opening is provided at one end of the tooling pad 8 for machining side strut forgings with U-shaped grooves.

[0009] Optionally, at least four locating pins 9 are provided, and the sliding fit distance between them and the profile tooling 3 is the width of the U-shaped groove, so that the profile tooling 3 has two parallel sliding directions along the locating pins 9.

[0010] The tooling proposed in this patent is simple to manufacture and can quickly position the forging blank, effectively improving product processing efficiency. By controlling the cutting edge distance and straightness of the forging blank through the positioning pin and limiting it through the stop pin, the cutting of the forging blank can be effectively prevented, thus improving the product qualification rate. The tooling is versatile and can be applied to the cutting edge of similar products by simply changing the size of the profile pad, the cylindrical pin, and adjusting the position of the positioning pin and the stop pin.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] According to one aspect of the present invention, a quick positioning and trimming fixture for side-strut forging blanks is provided, such as... Figure 1-5As shown, it includes: a profiled fixture 3, a cylindrical pin 4, a profiled pad 6, a fixture pad 8, a positioning pin 9, and a stop pin 10. The positioning pin 9 and the stop pin 10 are provided on the surface of the fixture pad 8. The profiled fixture 3 is installed on the surface of the fixture pad 8 and can slide along the positioning pin 9. The positioning pin 9 is used to constrain the sliding direction of the fixture pad 8. The stop pin 10 is provided at one end of the fixture pad 8 and is used to constrain the sliding termination position of the profiled fixture 3. The profiled fixture 3 is provided with a profiled pad 6 and a cylindrical pin 4 for positioning the side support rod forging blank 1. The upper surface of the profiled pad 6 contacts and matches the outer surface of the side support rod forging blank 1. The cylindrical pin 4 is used to pass through the positioning hole of the side support rod forging blank 1.

[0021] Furthermore, the profile tooling 3 also includes a push handle 5 / 7, which is used to push the profile tooling 3 to slide with external force, facilitating machining operations.

[0022] Furthermore, the locating pin 9 is used to constrain the tooling pad 8 to slide linearly, for machining forgings with linear profiles.

[0023] Furthermore, the molding pad 6 is made of plastic, which facilitates the creation of the top surface molding.

[0024] Furthermore, a U-shaped opening is provided at one end of the tooling pad 8 for machining side strut forgings with U-shaped grooves.

[0025] Furthermore, such as Figure 6-8 As shown, at least four locating pins 9 / 11 are provided, and the sliding fit distance between the locating pins 9 / 11 and the locating tool 3 is the width of the U-shaped groove, so that the locating tool 3 has two parallel sliding directions along the locating pins 9 / 11.

[0026] The workflow is as follows:

[0027] (1) Install the tooling pad 8 on the saw and tighten it. Calculate the position of the saw blade according to the distance of the U-shaped groove to be cut off from the workpiece 1, and install the saw blade on the saw at the same time. The position of the saw blade remains unchanged during the processing.

[0028] (2) Place the surface fixture 3 on the fixture pad 8. The surface fixture 3 is movable and can be pushed by pushing the handle 5 / 7.

[0029] (3) Install workpiece 1 on the profile tooling 3, and use the profile pad 6 and cylindrical pin 4 to quickly position and install the forging blank;

[0030] (4) Push the profile fixture 3 forward along the locating pin 9 until it hits the stop pin 10 and can no longer be pushed, thus completing the cutting of the upper side of the workpiece 1. See Figure 7 ;

[0031] (5) Move the profile fixture 3 backward along the locating pin 9 until it moves away from the saw blade, approximately to... Figure 5 After reaching the desired state, push the profile fixture 3 to the other side, allowing it to move forward along the locating pin 11 until it hits the stop pin 10 and can no longer be pushed. This completes the trimming of the lower side of workpiece 1. See [link / description]. Figure 8 At this point, the edge material that needs to be removed from workpiece 1 is completely cut off and separated from the forging blank;

[0032] (6) Move the profile tooling 3 backward along the positioning pin 11 until it leaves the saw blade, then remove the workpiece 1 and the edge material;

[0033] (7) Repeat steps 3, 4, 5 and 6 to complete the trimming of the next forging blank.

However, the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the scope of the claims.
