Description

Technical Field

[0001] This utility model relates to the technical field of calibrating frame-shaped parts, and in particular to a calibrating fixture for frame-shaped parts. Background Technology

[0002] The structure of the frame-shaped parts produced in a certain workshop is as follows: Figure 1 As shown, it consists of four side frames connected sequentially, forming a front connecting part 1, a rear connecting part 2, a left connecting part 3, and a right connecting part 4. The included angle between the front connecting part 1 and the rear connecting part 2 is 87-88°, while both the left connecting part 3 and the right connecting part 4 are obtuse angles. The manufacturing process requires that the angles of the front connecting part 1 and the rear connecting part 2 be corrected to 90°. After correction, the following is obtained: Figure 2 The finished parts shown.

[0003] The method for correcting frame-shaped parts in the workshop is as follows:

[0004] S1. The worker takes out a frame-shaped part to be corrected and places it flat on the platform;

[0005] S2. The worker uses two wooden hammers to lightly tap the rear connecting part 2 and the front connecting part 1 of the frame-shaped part, respectively, so that the front connecting part 1 and the rear connecting part 2 move in opposite directions. The tapping direction is as follows: Figure 1 As shown by the middle arrow, after tapping for a period of time, the angles of both the front connecting part 1 and the rear connecting part 2 can be corrected to 90°, thus obtaining the desired result. Figure 2 The finished parts shown.

[0006] However, while the methods used in the workshop can correct frame-shaped parts, the following technical shortcomings still exist in actual operation:

[0007] I. It requires manual tapping of the front connecting part 1 and the rear connecting part 2 with a wooden hammer to correct both parts to 90°. This undoubtedly takes a long time to complete the correction of a frame-shaped part, thus reducing the correction efficiency of the frame-shaped part.

[0008] II. There are 120 to 130 frame parts to be corrected in a day. The method of manually tapping them with a wooden hammer will undoubtedly take a long time to correct all the frame parts, further reducing the correction efficiency.

[0009] Therefore, there is an urgent need for a calibration fixture that can shorten the calibration time of frame-shaped parts and greatly improve the calibration efficiency of frame-shaped parts. Utility Model Content

[0010] The purpose of this invention is to overcome the shortcomings of the prior art and provide a correction fixture for frame-shaped parts that shortens the correction time and greatly improves the correction efficiency of frame-shaped parts.

[0011] The purpose of this utility model is achieved through the following technical solution: a correction fixture for frame-shaped parts, which includes a base, on which four extrusion components are evenly distributed around the center. The extrusion component located at the rear includes a strip groove formed on the top surface of the base and arranged longitudinally, and an end cap fixed at the outer end of the strip groove. A lead screw is rotatably installed between the end cap and the inner end of the strip groove. A first threaded sleeve and a second threaded sleeve are threadedly connected to the lead screw. Both the first threaded sleeve and the second threaded sleeve are slidably engaged with the strip groove.

[0012] The first threaded sleeve is located in front of the second threaded sleeve. A first fixing seat is fixed on the top surface of the first threaded sleeve. The outer end face of the first fixing seat is a V-shaped surface. A second fixing seat is fixed on the top surface of the second threaded sleeve. A V-shaped groove is formed on the inner end face of the second fixing seat. The V-shaped groove and the V-shaped surface form a V-shaped cavity.

[0013] The outer wall of the base is fixed with a handle for easy handling by workers.

[0014] The groove is rectangular.

[0015] The end cap is fixed to the base by multiple locking screws.

[0016] The outer end of the lead screw extends outside the end cap, and a handle is fixed on the extended end.

[0031] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description:

[0032] like Figures 3-7 As shown, a straightening fixture for frame-shaped parts includes a base 5. Four pressing components 6 are evenly distributed on the base 5 around its center. The pressing component 6 located at the rear includes a longitudinally arranged strip groove 7 formed on the top surface of the base 5 and an end cap 8 fixed at the outer end of the strip groove 7. The end cap 8 is fixed to the base 5 by multiple locking screws. The strip groove 7 is rectangular. A lead screw 9 is rotatably installed between the end cap 8 and the inner end of the strip groove 7. A first threaded sleeve 10 and a second threaded sleeve 11 are threadedly connected to the lead screw 9. Both the first threaded sleeve 10 and the second threaded sleeve 11 are slidably engaged with the strip groove 7. The outer end of the lead screw 9 extends outside the end cap 8, and a handle 18 is fixed on the extended end.

[0033] The first threaded sleeve 10 is located in front of the second threaded sleeve 11. A first fixing seat 12 is fixed on the top surface of the first threaded sleeve 10. The outer end face of the first fixing seat 12 is a V-shaped surface 13. A second fixing seat 14 is fixed on the top surface of the second threaded sleeve 11. A V-shaped groove 15 is opened on the inner end face of the second fixing seat 14. The V-shaped groove 15 and the V-shaped surface 13 form a V-shaped cavity 16.

[0034] A handle 17 is fixed on the outer wall of the base 5 to facilitate worker handling. A weight-reducing groove is provided on the base 5 between each pair of adjacent extrusion components 6.

[0035] The working process of this utility model is as follows:

[0036] S1. The worker lifts the entire base 5 using handle 17 and places the base 5 flat on the workbench.

[0037] S2, The worker takes out a... Figure 1 The frame-shaped part shown is to be corrected;

[0038] S3. The worker places the rear connecting part 2 of the frame-shaped part into the V-shaped cavity 16 of the rear extrusion assembly 6 and supports the rear connecting part 2 on the stepped surface of the first fixed seat 12. At the same time, the worker places the front connecting part 1 of the frame-shaped part into the V-shaped cavity 16 of the front extrusion assembly 6 and supports the front connecting part 1 on the stepped surface of the first fixed seat 12.

[0039] Simultaneously, the left connecting part 3 of the frame-shaped component is fitted into the V-shaped cavity 16 of the left-side extrusion assembly 6, and the left connecting part 3 is supported on the stepped surface of the first fixed base 12. At the same time, the right connecting part 4 of the frame-shaped component is fitted into the V-shaped cavity 16 of the right-side extrusion assembly 6, and the right connecting part 4 is supported on the stepped surface of the first fixed base 12, thereby achieving the installation of the frame-shaped component to be corrected. Figures 8-9 As shown;

[0040] S4. The worker uses his left hand to rotate the handle 18 of the rear extrusion assembly 6. The handle 18 drives the lead screw 9 to rotate. Under the threaded engagement, the first threaded sleeve 10 and the second threaded sleeve 11 of the rear extrusion assembly 6 both move forward along the length of the strip groove 7. The first threaded sleeve 10 and the second threaded sleeve 11 respectively drive the first fixed seat 12 and the second fixed seat 14 connected to them to move forward synchronously, thereby extruding the rear connecting part 2 of the frame-shaped part forward, so as to gradually increase the angle of the rear connecting part 2.

[0041] At the same time, the worker uses his right hand to rotate the handle 18 of the front extrusion assembly 6. The handle 18 drives the lead screw 9 to rotate. Under the threaded engagement, the first threaded sleeve 10 and the second threaded sleeve 11 of the front extrusion assembly 6 both move backward along the length of the strip groove 7. The first threaded sleeve 10 and the second threaded sleeve 11 respectively drive the first fixed seat 12 and the second fixed seat 14 connected to them to move backward synchronously, thereby extruding the front connecting part 1 of the frame part backward, so as to gradually increase the angle of the front connecting part 1.

[0042] After rotating the handle 18 by both hands to a certain angle, the worker uses calipers to measure the angles of the front connecting part 1 and the rear connecting part 2 of the frame-shaped part. If both the angles of the front connecting part 1 and the rear connecting part 2 are 90°, the frame-shaped part has been corrected. If the angles of the front connecting part 1 and the rear connecting part 2 are less than 90°, the worker repeats step S4 until the angles of the front connecting part 1 and the rear connecting part 2 are corrected to 90°, thus completing the correction of a frame-shaped part and obtaining the desired result. Figure 2 The finished parts shown;

[0043] S5. After the frame-shaped parts are corrected, the worker removes the corrected frame-shaped parts from the fixture.

[0044] S6. By repeating steps S2 to S5, workers can continuously correct multiple frame-shaped parts that need to be corrected.

[0045] As can be seen from steps S3 to S4, the worker only needs to install the frame-shaped part to be corrected onto the tooling, and then use his left and right hands to rotate the handle 18 of the rear pressing component 6 and the handle of the front pressing component 6 respectively, so that the front connecting part 1 and the rear connecting part 2 of the frame-shaped part can move in opposite directions, thereby quickly correcting the angles of the front connecting part 1 and the rear connecting part 2 to 90°, thus completing the correction of a frame-shaped part.

[0046] Therefore, compared to the calibration methods used in the workshop, this fixture eliminates the need for workers to repeatedly strike the front connecting part 1 and the rear connecting part 2 with a wooden hammer to complete the calibration. Instead, calibration can be completed simply by rotating the handle 18, thus greatly reducing the calibration time for a single frame-shaped part and significantly improving the calibration efficiency. Furthermore, because the calibration time for a single frame-shaped part is shortened, workers can calibrate hundreds of frame-shaped parts in a short time, further enhancing the calibration efficiency.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
