Description

Technical Field

[0001] This utility model relates to the technical field of bicycle parts processing equipment, and specifically discloses a bicycle frame tube profile included angle detection device. Background Technology

[0002] Bicycle frame tubes refer to the hollow tubular structures that make up the main body of a bicycle frame. They are the core skeleton assembled by welding or connecting them through specific geometric designs. Their main functions are to bear the rider's weight, transmit power, and support all components. A bicycle frame consists of a front triangle and a rear triangle. The front triangle is composed of the top tube, bottom tube, and head tube. During the production of the bicycle front triangle, an angle detection device is needed to detect the angle between the tubes to ensure the quality of the bicycle frame processing.

[0003] Chinese patent CN218329732U discloses a bicycle frame tube profile included angle detection device, relating to the field of bicycle parts processing technology. This utility model includes a base plate, with a raised edge on one side edge for abutting against one side of a tripod frame; a rotating rod rotatable on the base plate via a pivot; and an arc-shaped through hole centered on the pivot axis, with scale lines on the edge of the arc-shaped through hole. This invention first controls the rotating rod to rotate along the axis to the corresponding scale position according to the set angle of the tripod frame; then controls one side of the tripod frame to abut against the convex edge, and then slowly moves the tripod frame towards the rotating rod along the length of the convex edge. When one side of the tripod frame contacts the rotating rod, it is observed whether the tripod frame and the rotating rod are in partial or complete contact, thereby determining whether the angle of the tripod frame meets the requirements. However, the above device can only detect one included angle at a time during use. According to the principle that the sum of the interior angles of a triangle is equal to 180 degrees, at least two angles need to be detected to determine whether all three angles meet the requirements. Therefore, when it is necessary to detect another angle, the angle of the rotating rod needs to be adjusted and fixed again or another device needs to be used, which to some extent affects the efficiency of the tripod frame detection and the practicality of the above device. Therefore, in order to solve the above problems, this invention proposes a bicycle frame tube profile included angle detection device. Utility Model Content

[0004] The present invention aims to provide a bicycle frame tube profile included angle detection device, which can simultaneously detect whether two corners in the same triangular frame meet the requirements, thereby improving the efficiency of frame inspection and the practicality of the device.

[0005] This utility model is achieved through the following technical solution:

[0006] A bicycle frame tube profile includedr includes a base, a detection mechanism on top of the base, a frame tube body on the front side of the detection mechanism, a support plate on the base, a storage box below the support plate, and a vertical plate on the vertical plate. A circular plate is detachably connected to the lower end of the vertical plate, a scale plate is provided on the front side of the circular plate, a first mounting shaft is provided at the center of the front side of the circular plate, a first rotating rod is provided on the outer side of the first mounting shaft, a plurality of connecting blocks arranged in a linear array are provided at the end of the first rotating rod away from the first mounting shaft, a top block is provided at one end of each connecting block, a second mounting shaft is provided on the front side of the top block, a second rotating rod is provided on the outer side of the second mounting shaft, and a second auxiliary plate is detachably connected to the side of the second rotating rod near the vertical plate. Two electromagnets are connected inside the second auxiliary plate.

[0007] As a further feature of the above solution, rollers are connected to the four lower corners of the support plate, and at least one of the rollers is a brake wheel, which facilitates the adjustment and fixation of the device. A storage battery is provided on one side of the storage box, and a battery compartment is provided on the outside of the storage battery, which can power the electromagnet and reduce the dependence of the electromagnet and the device on an external power source.

[0008] As a further feature of the above solution, the interior of the upright plate is provided with a reserved hole to facilitate the passage of the power and signal wires of the electromagnet through the reserved hole, avoiding interference between the power and signal wires and the frame tube body. An arc-shaped hole is provided on one side of the reserved hole. A first nut is threadedly connected to the outer side of the first mounting shaft. A limiting shaft is connected to the side of the first rotating rod near the upright plate. The limiting shaft passes through the interior of the arc-shaped hole. A second nut is threadedly connected to the outer side of the limiting shaft, which can limit the position and angle of the first rotating rod.

[0009] As a further feature of the above solution, a first auxiliary plate is provided on the front side of the first rotating rod to facilitate contact with frame tube bodies of different diameters. A connecting groove is provided at one end of the first rotating rod, and a protrusion is provided at one end of both the connecting block and the top block. The protrusion is detachably connected to the connecting groove. A connecting groove is provided at the end of the connecting block away from the protrusion, so that the user can adjust the number of connecting blocks according to the model of the frame tube body.

[0010] As a further feature of the above scheme, a third nut is threaded onto the outer side of the second mounting shaft to facilitate the disassembly and assembly of the second rotating rod and to limit the angle of the second rotating rod.

[0011] As a further feature of the above solution, a controller is provided at one end of the base to facilitate the opening and closing of the electromagnet. The electromagnet is connected to the controller via a power line and a signal line.

[0012] In this utility model, the circular plate, the first mounting shaft, and the arc plate are all concentrically arranged. The 0-degree and 180-degree graduation lines of the scale plate are parallel to the upper plane of the support plate. The upright plate is made of an iron material that can be attracted by an electromagnet.

[0013] The present invention has the following beneficial effects during use:

[0014] The use of multiple casters in the base makes it easy to adjust the position of the device, and the use of the storage box makes it easy to place accessories such as the first auxiliary plate, the second auxiliary plate, the connecting block, and the three types of nuts in the device, making them convenient for users to access.

[0015] The combination of the top block and multiple connecting blocks in the testing mechanism allows users to adjust the number of connecting blocks between the first rotating rod of the top block according to the model of the frame tube body to be tested. This ensures that after one corner of the frame tube body abuts against the end of the first rotating rod away from the top plate, the sides of the second rotating rod and the first rotating rod can respectively contact the two sides of one corner of the frame tube body away from the first mounting axis, thereby achieving the purpose of simultaneously testing two corners and improving the efficiency of the included angle testing of the frame tube body.
