Description

Technical Field

[0001] This utility model relates to the field of twist drill testing fixtures, specifically a twist drill testing clamping tool. Background Technology

[0002] The main methods for testing twist drills include the following:

[0003] Diameter Measurement Method: Using calipers or other diameter measuring tools, measure the diameter at two opposite positions on the worn part of the twist drill. Calculate the difference between the two measurements to obtain the wear amount. Microscopic Measurement Method: Observe the morphology of the worn part of the twist drill under a microscope. By calculating the differences in parameters such as diameter, height, and cutting edge angle at different positions, the specific wear value can be obtained. Comparative Measurement Method: Compare a new standard drill bit with the twist drill to be tested. Calculate the wear amount by observing the differences in the worn parts between the two. Visual Inspection Method: Observe the back angle, cutting edge length, and symmetry of the twist drill with the naked eye to ensure that the two cutting edges are basically symmetrical. Using an Angle Gauge: Place one side of the angle gauge against the edge of the twist drill and the other side against the cutting edge of the drill bit to measure the cutting edge length and angle.

[0004] When using the diameter measurement method to inspect twist drills, it is necessary to measure the diameter of the twist drill at multiple points, which results in low inspection efficiency. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] This utility model provides a twist drill testing and clamping tool. Please refer to [link / reference]. Figure 1-4 It includes a support platform 1, on which a clamping mechanism is installed, and on which multiple auxiliary clamping components are installed;

[0027] When the clamping mechanism clamps the twist drill 12 to be tested, each auxiliary clamping component clamps the twist drill 12 simultaneously; and a vertical observation support column 6 is slidably connected on the support platform 1.

[0028] Both ends of the support platform 1 are provided with sliding grooves 3, and the bottom of the vertical observation support column 6 is detachably equipped with a slider 4, which is slidably connected to the inner wall of the sliding groove 3.

[0029] The top of the slider 4 is welded with a support connecting seat 5. The inner wall of the support connecting seat 5 is inserted with a vertical observation abutment 6. The vertical observation abutment 6 and the support connecting seat 5 are provided with internal threaded holes at corresponding positions. The vertical observation abutment 6 and the support connecting seat 5 are fixed together by bolts.

[0030] The clamping mechanism includes two U-shaped brackets 8, which are symmetrical about the support platform 1, and clamping components are fixedly installed at the top and bottom of the U-shaped brackets 8.

[0031] The clamping assembly includes a support block 14 welded to a U-shaped bracket 8. A first sliding rod 13 is slidably connected to the support block 14. A first spring 16 is sleeved on the first sliding rod 13. The two ends of the first spring 16 are fixedly connected to the support block 14 and the clamping plate 15, respectively. Under the elastic force of the two first springs 16, the two clamping plates 15 clamp the twist drill 12 tightly, and the twist drill 12 will not slip under the action of gravity.

[0032] The bottom of the U-shaped bracket 8 is welded with a U-shaped support rod 2, and the bottom of the U-shaped support rod 2 is welded to the support platform 1.

[0033] The first spring 16 has a first mounting plate 161 and a second mounting plate 162 welded to its two ends respectively. The first mounting plate 161 and the second mounting plate 162 are respectively bolted to the support block 14 and the clamping plate 15.

[0034] The auxiliary clamping assembly includes a second sliding rod 11 that is slidably connected to the U-shaped bracket 8. A ring 9 and a clamping plate 10 are welded to both ends of the second sliding rod 11, respectively. The height of the clamping plate 10 is set between 0.5 mm and 5 mm. A support ring 18 is fixedly installed on the second sliding rod 11. A second spring 17 is sleeved on the second sliding rod 11. The two ends of the second spring 17 are fixedly connected to the support ring 18 and the U-shaped bracket 8, respectively. Specifically, a third mounting plate 171 and a fourth mounting plate 172 are welded to both ends of the second spring 17, respectively. The third mounting plate 171 and the fourth mounting plate 172 are fixed to the support ring 18 and the U-shaped bracket 8 by bolts.

[0035] In practical use, the first sliding rod 13 and all the rings 9 are pulled outward to place the twist drill 12 between the clamping plates 10 on both sides. Under the elastic force of the first spring 16, the first sliding rod 13 drives the clamping plate 15 to clamp the twist drill 12.

[0036] When the ring 9 is released, each of the second springs 17 drives the second sliding rod 11 to approach the twist drill 12, thereby clamping the twist drill 12 against the clamping plate 10.

[0037] Move the vertical observation post 6 close to the ring 9. If the vertical observation post 6 can contact each ring 9 at the same time, it means that the diameter of the twist drill 12 is equal at all points. If the vertical observation post 6 cannot contact each ring 9 at the same time, the diameter of the twist drill 12 at different points (the clamping position of the clamping plate 10) is different.

[0038] Other positions of the twist drill 12 can be tested by moving the twist drill 12 up and down and repeating the above operation.

[0039] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
