Description

Technical Field

[0001] The utility model relates to the technical field of wire testing equipment, in particular to a wire scratch and abrasion resistance testing machine with a self-cleaning function. Background Art

[0002] The scratch and abrasion test of wires is a test method to evaluate the wear resistance of the wire sheath material. The test usually involves applying a certain force and friction on the wire surface to simulate the friction and scratching conditions that the wire may encounter during use. Therefore, a scratch and abrasion tester is required during the test.

[0003] After searching, a Chinese patent discloses a scratch and abrasion resistance testing machine for automotive wires with a self-cleaning effect (authorization announcement number CN211602772U). The patented technology includes a frame, a current sensor is installed at the lower left end of the frame, a connecting rod is connected to the outer lower end of the rotating rod, a slider is installed at the right end of the fixed column, both sides of the slider are connected to the sliding rod, a fixed frame is fixed to the lower end of the lifting rod, a placement plate is installed on the upper right surface of the frame, and the upper parts of both sides of the placement plate are connected to the connecting frame, a threaded rod is fixed on the upper side of the center of the connecting frame, and the lower end of the threaded rod is connected to an extrusion plate. Through the use of a rotating rod and a connecting rod, the patented technology allows the device to drive the connecting plate to slide and rotate, thereby driving the fixed column to slide repeatedly left and right, so that the slider can slide on the outside of the sliding rod, thereby driving the blade to complete the detection of the raw materials. The fully automated setting can improve its own work efficiency and reduce working time.

[0004] However, there are also several points that can be optimized when using this patented technology:

[0005] 1.

[0027] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, rather than all the embodiments. The components of the embodiment of the utility model generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents the selected embodiment of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] like Figure 1 and Figure 2 As shown, the utility model provides a technical solution: including a mounting mechanism, the mounting mechanism includes a base 1, the top of the base 1 is symmetrically fixedly connected with two U-shaped connecting frames 2, the top of the base 1 and the outsides of the two connecting frames 2 are symmetrically fixedly connected with two clamping plates 3, the inside of the clamping plate 3 is provided with a through groove for the passage of cables, the inside of the through groove is slid with a clamping splint, the clamping splint is adjusted by screws, the base 1 is set as a hollow structure, the top of the base 1 is equidistantly provided with dust dropping grooves 25, one side of the base 1 is set as an opening and is slidably connected with a dust drawer 26;

[0031] In summary, the dust drawer 26 disposed inside the base 1 can collect particles scraped off the cable surface, and the clamping plate 3 can fix both ends of the cable so that the cable can be fixed, thereby better performing the scraping test.

[0032] Example 2

[0033] like Figure 1 and Figure 2 As shown, the driving mechanism is arranged on the mounting mechanism, and the driving mechanism is used to drive the scraping end to run along a preset trajectory. The driving mechanism includes a polished rod 5 and a reciprocating screw rod 6. A through-structured slot body 4 is provided inside the connecting frame 2. The polished rod 5 is fixedly connected inside one of the slot bodies 4, and the reciprocating screw rod 6 is rotatably connected inside the other slot body 4. Connecting blocks 7 are arranged on the outside of the reciprocating screw rod 6 and the outside of the polished rod 5, wherein one connecting block 7 is threadedly connected to the reciprocating screw rod 6, and the other connecting block 7 is slidably connected to the polished rod 5, and a sliding rod 8 is fixedly connected between the two connecting blocks 7;

[0034] In summary, the sliding rod 8 can connect the two connecting blocks 7, so that the reciprocating screw 6 drives the connecting block 7 to move while driving the other connecting block 7 to move through the sliding rod 8, and the reciprocating screw 6 can transmit power through an externally installed motor or drive motor.

[0035] Example 3

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, a scraping mechanism is arranged on a driving mechanism, and the scraping mechanism is used to scrape the surfaces of cables of different types, and the scraping mechanism includes a limit block 9, and the number of the limit blocks 9 is set to two and they are all slidably connected to the outside of the sliding rod 8, and the top of the limit block 9 is fixedly connected with a scraper 10, and the scraper 10 is provided with an adjusting groove 11 inside, and the adjusting groove 11 is slidably connected with a connecting plate 12 inside, and a limit column 13 is fixedly connected between the two connecting plates 12, and the inside of the adjusting groove 11 and the outside of the limit column 13 are symmetrically fixedly connected with two fixed rods 14, and the connecting plates 12 are slidably connected with the corresponding fixed rods 14, and the outside of the fixed rod 14 and between the connecting plate 12 and the inner wall of the adjusting groove 11 are sleeved with a limit spring 15;

[0037] In summary, the limit block 9 slides on the sliding rod 8, so it can move to any position, and the two scrapers 10 are limited by the limit spring 15, so that the two are close to each other. When in use, the two scrapers 10 are separated first and the cable is placed between them. The scraper 10 will squeeze the limit spring 15 during the separation process, because when released, the limit spring 15 will push the two scrapers 10 closer together to make them contact with the cable surface.

[0038] Example 4

[0039] like Figure 1 , Figure 2 , Figure 3 and Figure 5The cleaning mechanism shown is arranged on the mounting mechanism, and the cleaning mechanism uses the power generated by the movement of the driving mechanism to clean the particles scraped by the scraping mechanism. The cleaning mechanism includes a transverse connecting rod 16, the number of which is set to two and is symmetrically fixedly connected between the two connecting frames 2. The outer side of the transverse connecting rod 16 is symmetrically slidably connected to two sliding blocks 17, and the outer side of the transverse connecting rod 16 and located between the corresponding sliding blocks 17 and the connecting frame 2 are symmetrically sleeved with two return springs 18, and a dust sweeping plate 19 is fixedly connected between the bottoms of the two corresponding sliding blocks 17. , bristles are arranged at the bottom of the dust sweeping plate 19, and the cleaning mechanism also includes a pulling rope 20, the number of the pulling rope 20 is set to two and fixedly connected to the side away from the two dust sweeping plates 19, and a notch 21 is opened inside the connecting frame 2, and a first limiting rotating wheel 22 and a second limiting rotating wheel 23 are arranged inside the notch 21 along the inner wall of the notch 21, and a fixed rotating wheel 24 is arranged at the ends away from the two connecting blocks 7, and the ends of the pulling rope 20 away from the dust sweeping plate 19 respectively bypass the corresponding first limiting rotating wheel 22 and the second limiting rotating wheel 23 and are tied to the outside of the fixed rotating wheel 24;

[0040] In summary, while the driving mechanism drives the scraper 10 to perform reciprocating scraping and grinding, the connecting block 7 will also drive the fixed rotating wheel 24 and the pulling rope 20 to move, and the movement of the pulling rope 20 will drive the dust sweeping plate 19 to move, and the dust sweeping plate 20 will pressurize the reset spring 18 during the movement, so that when the connecting block 7 returns to the preset position, the dust sweeping plate 20 can be reset by the reset spring 18, and the dust sweeping plate 20 can use the bristles to clean the particles in a large range and sweep them into the dust collection drawer 26 through the dust drop groove 25.

[0041] It should be noted that the first limit rotating wheel 22 and the second limit rotating wheel 23 can rotate by themselves, and what is described later is only the connection relationship between the rotating wheel mounting body and the notch 21:

[0042] The connection relationship between the first limit wheel 22, the second limit rotation 23 and the slot 21 needs to take into account the actual length of the device. When the length is short, the first limit wheel 22, the second limit rotation 23 and the slot 21 can be fixedly connected. Because the range of movement of the pull rope 20 is small, the first limit wheel 22 and the second limit rotation 23 can limit the pull rope 20 through their own structure. When the length is long, the first limit wheel 22, the second limit rotation 23 and the slot 21 must be set as a rotating connection to facilitate the coordination of the movement angle of the pull rope 20.

[0043] Working principle:

[0044] As shown in the figure, in actual use, first fix the two ends of the cable by the clamping plate 3, then separate the two scrapers 10 and place the cable in it. The scraper 10 will squeeze the limit spring 15 during the separation process, because when released, the limit spring 15 will push the two scrapers 10 closer together to make them contact with the surface of the cable. After that, the driving device provides rotational power to the reciprocating screw 6, and the sliding rod 8 connects the two connecting blocks 7, so that the reciprocating screw 6 drives the connecting block 7 to move while driving the other connecting block 7 to move through the sliding rod 8, so that the scraper 10 can reciprocate on the surface of the cable, and because the limit block 9 is a sliding type, therefore, the scraping test can be carried out regardless of whether the shape of the cable is standard or not, and while the scraper 10 moves, the connecting block 7 will also drive the fixed rotating wheel 24 and the pulling rope 20 to move, and the movement of the pulling rope 20 will drive the dust sweeping plate 19 to move, so that the coarse particles scraped by the scraper 10 are cleaned, and the particles in a large range are cleaned and swept into the dust accumulation drawer 26 through the dust falling groove 25. Through the above-mentioned arrangement, the device can not only carry out scraping tests on cables with different appearance conditions, but also has high practicality, and can collect the particles generated by scraping, which greatly improves the operation quality and use efficiency compared with traditional devices.

[0045] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the utility model.
