Description

Technical Field

[0001] The utility model relates to the technical field of bolt quality detection, in particular to a bolt detection device. Background Art

[0002] The bolts after upsetting need to be inspected for quality, to check whether the bending degree of the bolts after upsetting is qualified, whether the outer thread is crushed, and whether cracks appear on the outer side, so as to ensure the quality of the bolts after upsetting.

[0003] In the prior art, most of the bolts after upsetting are manually placed into a mold for inspection one by one, and the outer thread of the bolt is visually observed to see if it is crushed and whether there are cracks on the outer side. Although the pass rate can be guaranteed, one mold can only be used by one worker at most, and the number is limited and cannot be inspected in large quantities at the same time, which wastes time and the production efficiency cannot be guaranteed. Therefore, a solution to the above problem is proposed. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the shortcomings of the prior art, the utility model provides a bolt detection device, which has the advantages of accelerated detection time, improved production efficiency, and greatly reduced labor workload of workers. It solves the problem that in the prior art, most of the bolts after upsetting are manually placed into molds for detection one by one, and the outer thread of the bolt is observed with the naked eye to see whether it is crushed and whether there are cracks on the outer side. Although the pass rate can be guaranteed, one mold can only be used by one worker at most, and the number is limited and cannot be detected in large quantities at the same time, which wastes time and the production efficiency cannot be guaranteed.

[0006] (II) Technical solution

[0007] The utility model provides a technical solution to the above-mentioned technical problems as follows: a bolt detection device, comprising a detection platform, a conveyor belt is provided on the top of the detection platform, the conveyor belt comprises a guard plate, a motor driven by the conveyor belt is provided on the top of the detection platform, an electric push rod is provided on the top of the detection platform, an open groove adapted to the conveyor belt is opened on the top of the guard plate, an output end of the electric push rod is fixedly connected with a T-shaped push rod adapted to the open groove, the outer side of the T-shaped push rod is fixedly connected with a rack symmetrically distributed on the left and right, an auxiliary component meshing with the rack and extending above the conveyor belt is provided in the open groove on the rear side, a camera located above the conveyor belt is provided on the top of the detection platform, the camera is adapted to the open groove, and a control panel electrically connected to the motor, the electric push rod and the camera is provided on the top of the detection platform.

[0008] The beneficial effects of the utility model are:

[0009] The bolt detection device has a motor driving a conveyor belt to operate, and the bolts after being bent are placed on the top of the conveyor belt, which conveys the bolts. During this process, when the control panel observes through a camera that the bolt moves to the position directly below the camera, the control panel stops the motor, and the camera takes a picture of the bolt. The picture taken is transmitted to the control panel in the form of an electrical signal to analyze and compare the curvature of the bolt, whether the thread is crushed, and whether there are cracks on the appearance of the bolt. If the bolt is qualified, the control panel keeps the conveyor belt running, and then transports the bolt to the other end through the conveyor belt. If the bolt is unqualified, the control panel operates the electric push rod, and then drives the T-type push rod to push the bolt away from the conveyor belt through the front opening groove. During this process, the electric push rod drives the auxiliary component to move, and then limits the moving direction of the bolt to avoid the bolt rotating when pushing the bolt, resulting in failure to push the bolt away at one time. The device has the advantages of accelerated detection time, improved production efficiency, and greatly reduced labor workload for workers.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, a notch hole adapted to the open slot is provided on the top of the detection platform.

[0012] The beneficial effect of adopting the above further solution is that when a bolt is found to be unqualified after detection, the T-shaped push rod pushes the bolt away from the conveyor belt through the front opening groove, and the bolt can fall into the waste collection box through the notch hole.

[0013] Furthermore, the auxiliary component includes a first gear, a baffle rod and a second gear. The first gear is rotatably connected to the rear opening groove and is symmetrically distributed on the left and right and meshes with the adjacent rack. The baffle rod is rotatably connected to the rear opening groove and is symmetrically distributed on the left and right and extends to the top of the conveyor belt. The top of the baffle rod is fixedly connected to the second gear that meshes with the adjacent first gear.

[0014] The beneficial effect of adopting the above-mentioned further scheme is that the electric push rod operates, and then drives the T-shaped push rod to push the bolt away from the conveyor belt through the front opening groove. In this process, the T-shaped push rod drives the rack to move. Since the rack is engaged with the first gear, and the first gear is engaged with the second gear, it drives the barrier rod to rotate to the opposite side, thereby achieving the effect of limiting the movement space of the bolt, avoiding the bolt from rotating when pushing the bolt, resulting in unsuccessful pushing of the bolt.

[0015] Furthermore, the control panel is provided with a pause button, a start button and a push button.

[0016] The beneficial effect of adopting the above further scheme is that when the worker observes with the naked eye that the bolt is unqualified, when the bolt moves to the open slot, he presses the pause button, and then stops the motor from driving the conveyor belt through the control panel, and then presses the push button to operate the electric push rod, pushing the bolt away from the conveyor belt through the front open slot, and presses the start button to continue the operation of the device.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1, by Figure 1-4A bolt detection device is provided. The utility model comprises a detection platform 1. A conveyor belt 2 is provided on the top of the detection platform 1. The conveyor belt 2 comprises a guard plate 3. A motor 4 driven by the conveyor belt 2 is provided on the top of the detection platform 1. An electric push rod 5 is provided on the top of the detection platform 1. An open slot 6 adapted to the conveyor belt 2 is provided on the top of the guard plate 3. A T-type push rod 12 adapted to the open slot 6 is fixedly connected to the output end of the electric push rod 5. A rack 7 symmetrically distributed in left and right is fixedly connected to the outer side of the T-type push rod 12. An auxiliary component 8 meshing with the rack 7 and extending above the conveyor belt 2 is provided in the open slot 6 at the rear side. A camera 9 located above the conveyor belt 2 is provided on the top of the detection platform 1. The camera 9 is adapted to the open slot 6. A control panel 10 electrically connected to the motor 4, the electric push rod 5 and the camera 9 is provided on the top of the detection platform 1.

[0024] The top of the testing platform 1 is provided with a notch hole 11 adapted to the opening slot 6;

[0025] When a bolt is found to be unqualified after detection, the T-shaped push rod 12 pushes the bolt away from the conveyor belt 2 through the front opening slot 6, and the bolt can fall into the waste collection box through the notch hole 11;

[0026] The auxiliary component 8 includes a first gear 801, a stopper 802 and a second gear 803. The first gear 801 symmetrically distributed and meshing with the adjacent rack 7 is rotatably connected in the rear opening slot 6. The stopper 802 symmetrically distributed and extending above the conveyor belt 2 is rotatably connected in the rear opening slot 6. The top of each stopper 802 is fixedly connected with a second gear 803 meshing with the adjacent first gear 801.

[0027] The electric push rod 5 operates, and then drives the T-shaped push rod 12 to push the bolt away from the conveyor belt 2 through the front opening groove 6. In this process, the T-shaped push rod 12 drives the rack 7 to move. Since the rack 7 is engaged with the first gear 801, and the first gear 801 is engaged with the second gear 803, it drives the blocking rod 802 to rotate to the opposite side, thereby achieving the effect of limiting the movement space of the bolt, avoiding the bolt from rotating when pushing the bolt, resulting in unsuccessful pushing of the bolt.

[0028] In the second embodiment, the control panel 10 is provided with a pause button 13, a start button 14 and a push button 15;

[0029] When the worker observes with the naked eye that the bolt is unqualified, when the bolt moves to the open slot 6, the worker presses the pause button 13, and then stops the motor 4 from driving the conveyor belt 2 through the control panel 10, and then presses the push button 15 to operate the electric push rod 5, pushing the bolt away from the conveyor belt 2 through the front open slot 6, and presses the start button 14 to continue the operation of the device.

[0030] Working principle:

[0031] The first step to implement the innovation point:

[0032] Step 1: The motor 4 drives the conveyor belt 2 to operate, and the bolts after being bent are placed on the top of the conveyor belt 2. The conveyor belt 2 conveys the bolts. During this process, the control panel 10 observes through the camera 9 that when the bolt moves to the position directly below the camera 9, the control panel 10 stops the motor 4, and the camera 9 takes a picture of the bolt. The picture is transmitted to the control panel 10 in the form of an electrical signal to analyze and compare the curvature of the bolt, whether the thread is crushed, and whether there are cracks on the appearance of the bolt;

[0033] Step 2: If the bolt is qualified, the control panel 10 enables the conveyor belt 2 to continue to operate, and then the bolt is transported to the other end through the conveyor belt 2;

[0034] Step 3: If the bolt is unqualified, the control panel 10 activates the electric push rod 5, which then drives the T-shaped push rod 12 to push the bolt away from the conveyor belt 2 through the front opening groove 6. The bolt can fall into the waste product collection box through the notch hole 11. During this process, the T-shaped push rod 12 drives the rack 7 to move. Since the rack 7 is meshed with the first gear 801, and the first gear 801 is meshed with the second gear 803, the blocking rod 802 is driven to rotate to the opposite side, thereby achieving the effect of limiting the movement space of the bolt, avoiding the bolt from rotating when pushing the bolt, resulting in an unsuccessful push-off of the bolt. When the bolt falls, the device continues to operate.

[0035] The second innovation point implementation steps:

[0036] Step 1: When the worker observes that the bolt is unqualified through the naked eye, when the bolt moves to the open slot 6, the worker presses the pause button 13, and then stops the motor 4 from driving the conveyor belt 2 through the control panel 10;

[0037] Step 2: Press the push button 15 to operate the electric push rod 5, which then drives the T-shaped push rod 12 to push the bolt away from the conveyor belt 2 through the front opening slot 6, and the bolt can fall into the waste collection box through the notch hole 11;

[0038] Step 3: During the second step, the electric push rod 5 operates, and then drives the T-shaped push rod 12 to push the bolt away from the conveyor belt 2 through the front opening groove 6. During this process, the T-shaped push rod 12 drives the rack 7 to move. Since the rack 7 is meshed with the first gear 801, and the first gear 801 is meshed with the second gear 803, it drives the blocking rod 802 to rotate to the opposite side, thereby achieving the effect of limiting the movement space of the bolt, avoiding the bolt from rotating when pushing the bolt, resulting in unsuccessful pushing of the bolt.
