Description

Technical Field

[0001] The utility model relates to the technical field of thread detection equipment, and more specifically to a thread through gauge detection device. Background Art

[0002] After the nut is made, it is necessary to use a go / no-go gauge to test whether its thread meets the standard. After the nut is screwed to the stop end of the go / no-go gauge of the corresponding size, it is qualified if it cannot be screwed in after two turns. When it is screwed to the corresponding through end, the entire nut thread needs to be matched with the through end thread of the go / no-go gauge to prove it is qualified. Since a large number of turns are required, manual operation is extremely time-consuming and labor-intensive, and inefficient.

[0003] The existing patent is a thread go / no-go gauge detection device, and the patent authorization number is CN 208012477 U. The device has a simple structure, easy operation, time-saving and labor-saving detection, and high work efficiency.

[0004] However, in the patent authorization number CN 208012477 U, the nut to be tested, the go / no-go gauge, the hand-tight drill chuck, the bearing and the driven gear are arranged in sequence with the rotating shaft as the central symmetry axis, and then the nut to be tested is fixed by one hand, and the driving gear is rotated by the other hand by turning the handle. The rotation of the driving gear drives the driven gear to rotate, and the driven gear drives the rotating shaft to rotate, and the rotating shaft drives the rear sleeve of the hand-tight drill chuck to rotate. The rotation of the rear sleeve will cause the internal clamping jaws to rotate and move forward along the clamping jaw holes inside the front sleeve. The rotation and forward movement of the clamping jaws will cause the rotation and forward movement of the go / no-go gauge. Since the nut to be tested is stationary relative to the go / no-go gauge, the purpose of quickly screwing the through end of the go / no-go gauge into the nut to be tested can be achieved. Since in the process of detecting the nut, it is necessary to fix the nut to be tested with one hand and rotate the driving gear by turning the handle with the other hand, it is necessary to manually hold the nuts for inspection one by one, resulting in high labor intensity. In order to achieve automated inspection of the nuts, we propose a thread go / no-go gauge inspection device to solve the above-mentioned problems. Utility Model Content

[0022] 3. Beneficial effects

[0023] Compared with the prior art, the advantages of the present invention are:

[0024] (1) In this scheme, the nuts to be tested are placed in batches in an automatic feeder, and the nuts are transported one by one to the guide rail by using the feed rail. The nuts entering the guide rail are pushed to the clamp seat by extending the active end of the fourth double-acting cylinder, and then the nuts are clamped by the clamp seat by extending the active ends of the second double-acting cylinder and the third double-acting cylinder. The mounting seat and the slide seat cooperate with the guide rail to slide by extending the active end of the first double-acting cylinder, and the go / no-go gauge is driven to rotate by the power output end of the stepper motor. After the go / no-go gauge abuts against the nut, the mounting seat cooperates with the slide seat to rotate. The guide rod moves upward and uses the spring to buffer vibration, which plays a good protective role for the go / no-go gauge. If the entire screwing process goes smoothly and the through end of the go / no-go gauge can be completely screwed into the nut to be tested, the thread of the nut to be tested is qualified. If it cannot be screwed in the middle of screwing in, the thread of the nut to be tested is unqualified. The unqualified nuts are picked out manually, and the qualified nuts are contracted by the active end of the third double-acting cylinder, and the active end of the second double-acting cylinder is extended to push the qualified nuts into the feeding port and collect them. The degree of automation is high, which reduces the labor intensity of manual operation.

[0025] (2) In this solution, the bottom of the mounting seat is in contact with the rubber cap at the top of the damping rod, and the movable end of the damping rod is compressed to reduce energy transfer caused by vibration, impact or other forms of movement, thereby improving the energy absorption effect and avoiding the situation where the go / no-go gauge jumps up and down due to the rebound force of the spring, thereby ensuring that the go / no-go gauge can work normally.

[0033] Example:

[0034] See also Figure 1-4 , a thread gauge detection device, comprising a workbench 1;

[0035] The upper surface of the workbench 1 is fixedly connected with a vertical plate 2, and the surface of the vertical plate 2 is symmetrically fixedly connected with a guide rail 3, and the guide rail 3 is slidably connected with a slide seat 5 and a mounting seat 4 from top to bottom, respectively. A guide rod 6 penetrating the slide seat 5 is installed on the top of the mounting seat 4, and a spring 7 abutting against the slide seat 5 and the mounting seat 4 is sleeved on the outer side of the guide rod 6. A boss fixedly connected with the vertical plate 2 is arranged above the slide seat 5, and a first double-acting cylinder 8 with a movable end connected with the slide seat 5 is installed on the lower surface of the boss;

[0036] A stepper motor 9 is mounted on the surface of the mounting seat 4, and a go / no-go gauge 10 is mounted on the power output end of the stepper motor 9 through a chuck;

[0037] A second double-acting cylinder 12 and a third double-acting cylinder 13 mounted on the upper surface of the workbench 1 are respectively provided below the go / no-go gauge 10, and a clamping seat 14 corresponding to the go / no-go gauge 10 is installed at the movable ends of the second double-acting cylinder 12 and the third double-acting cylinder 13;

[0038] A material guide rail 15 fixedly connected to the workbench 1 is provided on one side of the clamp seat 14, and a fourth double-acting cylinder 18 is installed at one end of the material guide rail 15 away from the clamp seat 14, and the movable end of the fourth double-acting cylinder 18 extends to the inner side of the material guide rail 15;

[0039] An automatic feeder 16 is installed on one side of the workbench 1, and a feeding rail 17 extending to the inner side of the guide rail 15 is installed on the top of the automatic feeder 16;

[0040] A feeding port 19 is provided on the surface of the workbench 1 corresponding to the third double-acting cylinder 13;

[0041] It should be noted that when the thread gauge detection device is in use, the first double-acting cylinder 8, the second double-acting cylinder 12, the third double-acting cylinder 13 and the fourth double-acting cylinder 18 are externally connected to a pneumatic control device, and the pneumatic control device is used to control the extension and retraction of the movable ends of the first double-acting cylinder 8, the second double-acting cylinder 12, the third double-acting cylinder 13 and the fourth double-acting cylinder 18 respectively. By placing the nuts to be detected in batches in the automatic feeder 16, the nuts are transported one by one to the guide rail 15 by the feeding rail 17, and the nuts entering the guide rail 15 are pushed to the clamp seat 14 by extending the movable end of the fourth double-acting cylinder 18, and then the nuts are clamped by the clamp seat 14 by extending the movable ends of the second double-acting cylinder 12 and the third double-acting cylinder 13, and the nuts are moved by the movable end of the first double-acting cylinder 8. The end is extended to make the mounting seat 4 and the slide seat 5 cooperate with the guide rail 3 to slide, and the power output end of the stepper motor 9 drives the go / no-go gauge 10 to rotate. After the go / no-go gauge 10 abuts against the nut, the mounting seat 4 cooperates with the guide rod 6 to move upward and use the spring 7 to buffer the vibration, which plays a good protective role for the go / no-go gauge 10. If the entire screwing process is smooth, the through end of the go / no-go gauge 10 can be completely screwed into the nut to be tested, then the thread of the nut to be tested is qualified. If it cannot be screwed in the middle of screwing, the thread of the nut to be tested is unqualified. The unqualified nuts are picked out manually, and the qualified nuts are contracted by the active end of the third double-acting cylinder 13, and the active end of the second double-acting cylinder 12 is extended to push the qualified nuts into the discharge port 19 and collect them. The degree of automation is high, which reduces the labor intensity of manual operation.

[0042] like Figure 1 , Figure 2 As shown, the slide seat 5 and the mounting seat 4 are both provided with a slide groove that matches the guide rail 3 with clearance;

[0043] It should be noted that the stability of the slide seat 5 and the mounting seat 4 in cooperation with the guide rail 3 during the sliding process is ensured.

[0044] like Figure 3 As shown, a limit block is installed on the top of the guide rod 6 to abut against the top of the slide seat 5;

[0045] It should be noted that the guide rod 6 is limited by setting a limit block, thereby ensuring that the mounting seat 4 can move up and down in coordination with the slide seat 5 and cooperate with the spring 7 for buffering.

[0046] like Figure 2 As shown, a bracket fixedly connected to the vertical plate 2 is symmetrically arranged below the mounting seat 4, and a damping rod 11 whose movable end corresponds to the mounting seat 4 is installed at the bracket, and a rubber cap is installed at the end of the movable end of the damping rod 11;

[0047] It should be noted that, by abutting the bottom of the mounting seat 4 with the top rubber cap of the damping rod 11, the movable end of the damping rod 11 is compressed, reducing the energy transfer caused by vibration, impact or other forms of movement, thereby improving the energy absorption effect and avoiding the rebound force of the spring 7 causing the go / no-go gauge 10 to jump up and down, thereby ensuring that the go / no-go gauge 10 can work normally.

[0048] like Figure 3 As shown, a guide slope is provided at one end of the guide rail 15 close to the clamp seat 14;

[0049] It should be noted that the nut located inside the guide rail 15 can be guided to the clamping seat 14 through the guiding inclined surface.

[0050] like Figure 4 As shown, the bottom of the material discharge port 19 is provided with a material guide plate 20 fixedly connected to the bottom of the workbench 1, and the material guide plate 20 protrudes from the edge of the workbench 1;

[0051] It should be noted that the finished nuts dropped from the discharge port 19 can be collected by providing the guide plate 20 .

[0052] When in use: the first double-acting cylinder 8, the second double-acting cylinder 12, the third double-acting cylinder 13 and the fourth double-acting cylinder 18 are externally connected to a pneumatic control device, and the pneumatic control device is used to control the extension and retraction of the movable ends of the first double-acting cylinder 8, the second double-acting cylinder 12, the third double-acting cylinder 13 and the fourth double-acting cylinder 18 respectively, by placing the nuts to be tested in batches in the automatic feeder 16, and using the feeding rail 17 to transport the nuts one by one to the guide rail 15, and by extending the movable end of the fourth double-acting cylinder 18, the nuts entering the guide rail 15 are pushed to the clamp seat 14, and then the movable ends of the second double-acting cylinder 12 and the third double-acting cylinder 13 are extended to clamp the nuts using the clamp seat 14, and the movable end of the first double-acting cylinder 8 is used to extend the nuts. The elongation makes the mounting seat 4 and the slide seat 5 cooperate with the guide rail 3 to slide, and the power output end of the stepper motor 9 drives the go / no-go gauge 10 to rotate. After the go / no-go gauge 10 abuts against the nut, the mounting seat 4 cooperates with the guide rod 6 to move upward and uses the spring 7 to buffer the vibration, which plays a good protective role for the go / no-go gauge 10. If the entire screwing process goes smoothly and the through end of the go / no-go gauge 10 can be completely screwed into the nut to be tested, the thread of the nut to be tested is qualified. If it cannot be screwed in the middle of screwing, the thread of the nut to be tested is unqualified. The unqualified nuts are picked out manually, and the qualified nuts are contracted by the active end of the third double-acting cylinder 13, and the active end of the second double-acting cylinder 12 is extended to push the qualified nuts into the discharge port 19 and collect them, with a high degree of automation.

[0053] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
