Description

Technical Field

[0001] This utility model belongs to the field of anti-slip nail wear resistance testing technology, specifically relating to a cemented carbide anti-slip nail wear resistance testing fixture. Background Technology

[0002] Anti-skid studs made of cemented carbide are small in size, weighing only 0.2-0.3 grams each, with an outer diameter of 2-3 mm and a height of 5-6 mm. Their wear resistance cannot be tested using conventional methods. Conventional wear resistance tests use 50×50×10 mm plates. However, anti-skid stud wear resistance testing simulates the studs being embedded in a tire. It's not feasible to use 50×50×10 mm plates made from the same grade and batch of material for wear resistance testing; therefore, anti-skid studs must be used. Consequently, there is an urgent need for a cemented carbide anti-skid stud wear resistance testing fixture to achieve this capability. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] refer to Figure 7 As shown, the wear resistance testing fixture for carbide anti-slip nails provided by this utility model includes: a first fixture 4, a rectangular inlay groove 12 extending through the first fixture 4, a plurality of anti-slip nails being sequentially inlaid in the inlay groove 12, and glue for bonding being filled between adjacent anti-slip nails.

[0024] As described above, when using the first clamp 4 provided by this utility model, multiple anti-slip nails can be easily embedded and installed on the first clamp 4 through the inlay groove 12 on the first clamp 4. The depth of the inlay groove 12 is less than the length of the anti-slip nail, and the connection between multiple anti-slip nails can be improved by using glue.

[0025] In this utility model, combined with Figure 1-4 As shown, a second clamp 6 is also inclinedly provided below the first clamp 4 in this embodiment. The first clamp 4 is detachably installed on the second clamp 6. The second clamp 6 is inclined so that multiple anti-slip pins are stably placed in the inlay groove 12.

[0026] As described above, when using the second clamp 6 provided by this utility model, the first clamp 4 can be tilted by the second clamp 6, which makes it easier to place multiple anti-slip nails in the inlay groove 12 in sequence, and in this process, the anti-slip nails can be prevented from tipping over in the inlay groove 12.

[0027] Furthermore, to facilitate the detachable mounting of the first clamp 4 onto the second clamp 6, refer to... Figure 6-7As shown, the second clamp 6 has two symmetrically arranged positioning pins 15, and the first clamp 4 has two diagonally through-holes 17. The two positioning pins 15 are respectively inserted into the two positioning holes 17. The first clamp 4 has two fixing bolts 3, and each of the two positioning pins 15 has a threaded hole 16 to accommodate the insertion of the fixing bolts 3. After removing the fixing bolts 3, the first clamp 4 can be removed from the two positioning pins 15. At this time, the first clamp 4 can be disconnected from the second clamp 6, which facilitates the inspection and replacement of the first clamp 4.

[0028] In this utility model, combined with Figure 5 As shown, the second clamp 6 of this embodiment is also provided with a heating mechanism on the side opposite to the first clamp 4. The heating mechanism includes a heating shell 5 and a plurality of heating rods 13. A heating chamber 14 for accommodating the plurality of heating rods 13 is formed between the heating shell 5 and the second clamp 6.

[0029] As described above, when using the heating mechanism provided by this utility model, the glue between multiple anti-slip nails can be heated by the heating rod 13, thereby removing the glue between the anti-slip nails and making it easier to remove the anti-slip nails from the inlay groove 12.

[0030] In this utility model, combined with Figure 1-4 As shown, the second clamp 6 in this embodiment is further provided with an adjustment mechanism for adjusting the tilt angle. The adjustment mechanism includes a base 1 and a rotating seat 2. The rotating seat 2 is welded to the base 1. One end of the bottom of the second clamp 6 is rotatably mounted on the rotating seat 2. A flipping mechanism for flipping is provided between the bottom of the second clamp 6 away from the rotating seat 2 and the base 1.

[0031] Combination Figure 1-4 As shown, the flipping mechanism includes a connecting rod 7, a screw 9, and a motor 10. The top of the base 1 has a groove 11 along the flipping direction of the second clamp 6. The screw 9 is rotatably installed in the groove 11. A screw sleeve 8 is fitted on the screw 9. The two ends of the connecting rod 7 are rotatably installed on the second clamp 6 and the screw sleeve 8, respectively. The motor 10 is installed in the base 1, and the output end of the motor 10 is connected to one end of the screw 9.

[0032] As described above, when using the adjustment mechanism provided by this utility model, the base 1 in the adjustment mechanism provides an installation position for the rotating seat 2 and the flipping mechanism. After multiple anti-slip nails are installed in the inlay groove 12, the motor 10 starts and moves the connecting rod 7 through the screw 9 and the screw sleeve 8, thereby driving the second clamp 6 to rotate on the rotating seat 2, and then driving the first clamp 4 to lie flat, so that the detection end of the wear-resistant testing equipment can be tightly fitted with multiple anti-slip nails.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
