Description

Technical Field

[0001] This utility model relates to the field of drive chain technology, and in particular to a drive chain tilt angle testing device. Background Technology

[0002] The drive chain plays a core role in power transmission in mechanical systems. The main components of the drive chain include chain plates, pins, bushings, and rollers. After the chain plates are processed, their tilt angle needs to be tested to avoid excessive tilting of the chain plates, which would affect the pass rate of the subsequent assembled drive chain products.

[0003] The performance testing of the drive chain mainly relies on manual visual observation of its curvature to judge its condition, which brings many challenges. Manual testing is not only time-consuming and labor-intensive, but also, due to its reliance on personal experience, the test results are not consistent and are easily affected by human factors, thus affecting the quality and safety of the product. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a drive chain tilt angle testing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drive chain tilt angle testing device includes a support frame with a conveyor belt fixed inside and a contact sensor. A support plate is fixedly connected to the top inner wall of the support frame, and the support plate is in contact with the belt on the conveyor belt. Two fixed frames are fixedly connected to the top of the support frame, and a support rod is fixedly connected between the top of the two fixed frames. Two telescopic rods are fixedly connected to the bottom of the support rod, and a connecting frame is fixedly connected between the extended ends of the two telescopic rods. A rotating roller is movably connected to the connecting frame. A lead screw is movably connected to the support rod, and a connecting plate is movably connected to the bottom end of the lead screw. A mounting plate is installed on the bottom of the connecting plate through a guide assembly. The contact sensor is fixed to the bottom of the mounting plate.

[0007] As a further improvement of this utility model, an indicator light is fixedly connected to one side of each of the two fixing brackets, and the indicator light is electrically connected to the contact sensor.

[0008] As a further embodiment of this utility model, the guide assembly includes two slide rods, which are fixed to the upper surface of the mounting plate by bolts, and the slide rods are slidably connected to the connecting plate. The top end of the slide rod passes through the connecting plate and is fixedly connected to a retaining ring.

[0009] As a further embodiment of this utility model, two positioning posts are fixedly connected to the upper surface of the connecting plate, and the two positioning posts are slidably connected to the support rod.

[0010] As a further embodiment of this utility model, a collection box is placed in the cavity at one end of the support frame.

[0011] As a further embodiment of this utility model, two baffles are fixedly connected to the inner wall of one end of the support frame, and the collection box is in contact with the baffles.

[0012] As a further embodiment of this utility model, a locking nut is movably connected to the outer side of the lead screw, and the locking nut is in contact with the connecting plate by compression.

[0013] As a further improvement of this invention, the contact sensor can be in contact with the top of the connecting frame.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model uses a connecting frame in conjunction with a contact sensor. When the tilt angle of the drive chain is abnormal and does not meet the required standard, the contact sensor is triggered, and the control indicator light illuminates, thereby detecting that the tilt angle exceeds the set range and intuitively alerting the staff. This facilitates timely detection of problems, avoids the time-consuming and laborious nature of manual inspection, and improves the detection effect of the device.

[0016] 2. This utility model uses a mounting plate to drive a sliding rod to move upward along the connecting plate, which avoids excessive pressure on the contact sensor and damage, extends the sensor's service life, and further ensures stable operation of the equipment.

[0017] 3. This utility model adjusts the height of the connecting plate and the contact sensor by rotating the lead screw, which makes it convenient for operators to adjust the allowable tilt angle deviation range of the drive chain plate according to different needs, adapting to a variety of different testing standards and requirements, and enhancing the versatility of the equipment.

[0018] 4. This utility model uses a collection box to collect the tested chain plates, which facilitates centralized processing by staff. At the same time, the baffle restricts the position of the collection box, making it easy to position and retrieve the collection box, thus improving processing efficiency.

Detailed Implementation

[0023] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0024] Reference Figures 1-3 A drive chain tilt angle testing device includes a support frame 2 with a conveyor belt 4 fixed inside and a contact sensor 19, the contact sensor 19 being model JYB-KB-CW-2000.

[0025] The top inner wall of the support frame 2 is fixed with a support plate 5 by bolts, and the support plate 5 is in contact with the belt on the conveyor belt 4, and the support plate 5 supports the conveyor belt 4.

[0026] The top of the support frame 2 is fixed with two fixed frames 1 by bolts. The top of the two fixed frames 1 is fixed with a support rod 11 by bolts. The bottom of the support rod 11 is fixed with two telescopic rods 9 by bolts. The extended ends of the two telescopic rods 9 are fixed with a connecting frame 7 by bolts. The telescopic rods 9 can guide the connecting frame 7.

[0027] A rotating roller 8 is rotatably connected to the connecting frame 7, and the drive chain plate is conveyed by the conveyor belt 4 until the chain plate moves to the bottom of the rotating roller 8.

[0028] In particular, a lead screw 13 is threaded onto the support rod 11, and a connecting plate 16 is rotatably connected to the bottom end of the lead screw 13 via a bearing. An mounting plate 18 is installed on the bottom of the connecting plate 16 via a guide assembly.

[0029] The guide assembly includes two slide rods 10, which are fixed to the upper surface of the mounting plate 18 by bolts. The slide rods 10 are slidably connected to the connecting plate 16. The top of the slide rod 10 passes through the connecting plate 16 and is fixed with a retaining ring 15 by bolts. The retaining ring 15 can limit the height of movement of the slide rod 10 and prevent the slide rod 10 from separating from the connecting plate 16.

[0030] The contact sensor 19 is fixed to the bottom of the mounting plate 18 and can contact the top of the connecting bracket 7.

[0031] One side of each of the two fixed frames 1 is fixed with an indicator light 17 by bolts, and the indicator light 17 is electrically connected to the contact sensor 19. During the process of the conveyor belt 4 conveying the chain plate, if the chain plate meets the required standard, the chain plate passes directly through the gap between the rotating roller 8 and the conveyor belt 4.

[0032] If the drive chain tilt angle is abnormal and does not meet the required standard, i.e., the tilt is too high, the chain plate pushes the rotating roller 8 to move upward, and the connecting frame 7 moves upward with it. The connecting frame 7 moves upward so that its top contacts the contact sensor 19. The contact sensor 19 triggers a signal, and the control indicator light 17 lights up, thereby prompting the operator that the tilt angle is out of the set range.

[0033] It should be noted that the rotating screw 13 can adjust the height of the connecting plate 16 and the contact sensor 19, thereby facilitating the operator to adjust the allowable tilt angle deviation range of the drive chain plate according to the needs. The upper surface of the connecting plate 16 is fixed with two positioning posts 14 by bolts, and the two positioning posts 14 are slidably connected to the support rod 11. The positioning posts 14 can guide the connecting plate 16 so that it can move up and down stably and avoid the connecting plate 16 tilting during the up and down movement.

[0034] A collection box 3 is placed in the cavity at one end of the support frame 2. The collection box 3 can collect the chain plate after the test, which is convenient for staff to handle in a centralized manner.

[0035] Two baffles 6 are fixed to the inner wall of one end of the support frame 2 by bolts, and the collection box 3 is in contact with the baffles 6. The baffles 6 can restrict the position of the collection box 3, and at the same time facilitate the positioning, placement and removal of the collection box 3. The outer thread of the lead screw 13 is connected to a locking nut 12, and the locking nut 12 is in contact with the connecting plate 16. The locking nut 12 can further restrict and fix the position of the lead screw 13.

[0036] Working principle: When it is necessary to check whether the tilt angle of the drive chain plate meets the required standard:

[0037] Material conveying: The drive chain plate is conveyed by the conveyor belt 4, while the support plate 5 supports the conveyor belt 4 until the chain plate moves to the bottom of the rotating roller 8.

[0038] Tilt detection:

[0039] During the process of conveying the chain plate by the conveyor belt 4, if the chain plate meets the required standards, the chain plate passes directly through the gap between the rotating roller 8 and the conveyor belt 4.

[0040] If the drive chain tilt angle is abnormal and does not meet the required standard, i.e., the tilt is too high, the chain plate pushes the rotating roller 8 to move upward, and the connecting frame 7 moves upward with it. The connecting frame 7 moves upward so that its top contacts the contact sensor 19. The contact sensor 19 triggers a signal, and the control indicator light 17 lights up, thereby prompting the staff that the tilt angle is out of the set range.

[0041] When the tilt angle of the chain plate is large, the connecting frame 7 on the rotating roller 8 pushes the contact sensor 19 upward, thereby causing the mounting plate 18 to drive the slide bar 10 to move upward along the connecting plate 16, thus preventing the contact sensor 19 from being damaged due to excessive pressure.

[0042] Parameter adjustment:

[0043] The rotating lead screw 13 can adjust the height of the connecting plate 16 and the contact sensor 19, thereby facilitating the operator to adjust the allowable tilt angle deviation range of the drive chain plate according to the needs. After adjustment, the position of the lead screw 13 is further fixed by the locking nut 12.

[0044] Material collection: After testing, the chain plate material falls into the collection box 3 at the end of the conveyor belt 4 for collection.

Many more modifications can be made based on the teachings of this utility model, and all such modifications fall within the scope of protection claimed by this utility model.
