Description

Technical Field

[0001] This application relates to the technical field of positioning fixtures, and in particular to a bicycle frame positioning fixture. Background Technology

[0002] The frame, as the skeleton of the entire bicycle, determines and influences the correctness and comfort of the riding posture to the greatest extent. The frame components are the basic structural body of the bicycle, as well as its skeleton and main body. Other components are also directly or indirectly installed on the frame. The frame is made by cutting, shaping and welding tubes of different sizes. Some frame tubes need to be drilled at the ends for later processing.

[0003] The existing publication number CN221313332U, entitled "A Drilling and Positioning Fixture for Vehicle Frame Tubes," comprises a base, a fixing mechanism, a positioning mechanism, and a moving plate. Two slide blocks are symmetrically mounted on the left and right ends of the upper surface of the base, each with a T-slot on its upper surface. Two fixing seats are symmetrically mounted longitudinally in the middle of the upper surface of the base, and a lead screw shaft is rotatably mounted between the two fixing seats via a bearing seat. Two T-shaped slide rails are symmetrically mounted on the left and right ends of the bottom of the moving plate, slidingly mounted to the two slide blocks respectively. A threaded block is mounted near the front end of the bottom of the moving plate, and the threaded block is helically connected to the lead screw shaft. A row of arc-shaped grooves is equidistantly formed on the upper surface of the moving plate. Two fixing mechanisms are symmetrically mounted on the left and right ends of the upper surface of the moving plate, and a positioning mechanism is mounted on the right side of the moving plate. This utility model enables the simultaneous fixing of multiple vehicle frame tubes for sequential drilling, greatly improving drilling efficiency and demonstrating strong practicality.

[0004] Regarding the aforementioned technologies, the inventors discovered that when drilling holes in the frame, it is necessary to use a pressure plate to press down multiple frames in the groove of a moving plate, and then drill holes in multiple frames sequentially. Drilling holes sequentially can only be done in a single position, and it is impossible to adjust the drilling position of the frame laterally according to actual needs. Later, multiple frames are disassembled and the drilling position of the frame is adjusted one by one, which is a cumbersome process and reduces the efficiency of drilling holes in the frame. Utility Model Content

[0005] To overcome the shortcomings of existing methods that require pressing multiple bicycle frames into grooves on a moving plate and sequentially drilling holes in each frame, which only allows drilling at a single location and cannot be adjusted laterally according to actual needs, and which involves disassembling multiple frames and adjusting the hole positions one by one, resulting in cumbersome steps and reduced efficiency, this application provides a bicycle frame positioning fixture.

[0006] The bicycle frame positioning fixture provided in this application adopts the following technical solution:

[0007] A bicycle frame positioning fixture includes a processing table, a motor, and a limiting component. The motor is horizontally fixed to one side of the top surface of the processing table, and a limiting component is provided at the output end of the motor. The limiting component includes a rod, a locking component, and a push motor. The rod is fixed to the output end of the motor, and a locking component is horizontally slidably assembled at one end of the rod. A push motor is horizontally fixed at the other end of the rod, and a push wheel is fixed at the output end of the push motor. The locking component includes a perforated plate, which is horizontally slidably assembled on the rod. Two locking frames are symmetrically arranged horizontally on the front end face of the perforated plate, and multiple through holes are horizontally opened on the top surface of each of the two locking frames.

[0008] By adopting the above technical solution, the bicycle frame requiring drilling is placed between two clamping frames, and then the clamping frames are assembled at the opening of the clamping frame on the perforated plate. This clamping and limiting mechanism keeps the bicycle frame stable during drilling. When drilling, the motor on the processing table is started to drive the rod on the limiting component to deflect according to the drilling requirements, causing the clamped and limited bicycle frame to deflect at a suitable angle. This facilitates the later adjustment of the bicycle frame drilling angle. During drilling, the perforated plate slides horizontally on the rod, and the clamped and limited bicycle frame moves laterally, facilitating the lateral movement and switching of the drilling position of the clamped and limited bicycle frame. This allows for lateral adjustment of the frame drilling position according to actual needs, reducing steps and improving the efficiency of frame drilling.

[0009] Optionally, a slot is horizontally opened on the top surface of one of the two card frames, and an insert is horizontally fixed on the top surface of the other card frame, and the insert slides into the slot.

[0010] By adopting the above technical solution, when the two card frames are assembled together to limit and clamp the frame, in order to improve the convenience of assembling and inserting the two card frames, the insert block is slidably inserted into the slot to facilitate the guidance of the assembly of the two card frames.

[0011] Optionally, a rod is horizontally fixed to the lower side of one of the two card frames, and a screw hole is horizontally opened through the lower side of one of the two card frames.

[0012] By adopting the above technical solution, the insert rod and screw hole fixed on the lower side of one of the two card frames are used to guide the two card frames to be assembled together later.

[0013] Optionally, the other lower side of the two card frames has a horizontal through-hole, and the through-hole is slidably inserted into the insertion rod. The other lower side of the two card frames is rotatably connected with a bolt, and the bolt thread passes through the screw hole on the other card frame.

[0014] By adopting the above technical solution, when the two card frames are assembled together, the insert rod on one card frame slides through and is inserted into the insertion hole of the other card frame. The horizontal guide supports the assembly of the two card frames together, and the bolt thread on the rotating card frame is assembled into the screw hole of the other card frame, thus completing the locking and clamping of the two card frames to keep the bicycle frame stable.

[0015] Optionally, a rotating bar is vertically fixed to the vertical end face of the perforated plate near the drive motor, and a rotating wheel is horizontally rotatably connected to the end of the rotating bar.

[0016] By adopting the above technical solution, the rotating bar on the perforated plate is rotatably connected to the rotating wheel, which facilitates the subsequent rotation to push the perforated plate to slide on the bar and change the position of the opening of the bicycle frame that is engaged.

[0017] Optionally, a spring is horizontally fixed on the vertical end face of the other side of the orifice plate, and the other end of the spring is fixed to the end of the rod.

[0018] By adopting the above technical solution, the spring horizontally installed between the orifice plate and the rod facilitates the use of spring deformation force to push the orifice plate to slide horizontally on the rod back to its original position.

[0019] Optionally, multiple helical tubes are evenly and vertically arranged on the outer circumference of the pusher, and one end of each helical tube is rotatably connected to the outer circumference of the pusher.

[0020] By adopting the above technical solution, multiple helical tubes on the outer circumference of the push wheel rotate on the push wheel, which makes it easy to vertically adjust the position of the bicycle frame opening according to the position of the bicycle frame opening.

[0021] Optionally, a stud is threaded into the spiral tube, and an arc-shaped push block is fixed to the outer end of the stud.

[0022] By adopting the above technical solution, according to the requirements of the opening position of the bicycle frame, the rotating tube rotates on the push wheel, pushing the stud to move vertically in the tube. Thus, by the length of the stud extending out of the tube, it is easy to start the push motor to drive the push wheel to rotate, which drives push blocks of different lengths to press against the rotating wheel. The push blocks of different lengths push the hole plate on the rod to slide horizontally, driving the clamped bicycle frame to move laterally and change the horizontal opening position.

[0023] In summary, this application includes at least one of the following beneficial technical effects: During use, the bicycle frame requiring drilling is placed between two clamping frames, and then the clamping frames are assembled at the openings of the perforated plate. This ensures the bicycle frame remains stable during drilling. When drilling, the motor on the processing table is activated to rotate the rod on the limiting component, causing the clamped bicycle frame to deflect at a suitable angle. This facilitates subsequent changes to the drilling angle. During drilling, the perforated plate slides horizontally on the rod, allowing the clamped bicycle frame to slide laterally, facilitating the switching of the drilling position. This allows for adjustment of the frame drilling position according to actual needs, reducing steps and improving the efficiency of frame drilling. Attached Figure Description

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a bicycle frame positioning fixture. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4A bicycle frame positioning fixture includes a processing table 1, a motor 2, and a limiting component 3. The motor 2 is horizontally fixed on one side of the top surface of the processing table 1, and the limiting component 3 is provided at the output end of the motor 2. The limiting component 3 includes a rod 31, a snap-fit ​​component 32, and a push motor 33. The rod 31 is fixed at the output end of the motor 2, and the snap-fit ​​component 32 is horizontally slidably assembled at one end of the rod 31. The push motor 33 is horizontally fixed at the other end of the rod 31, and a push wheel 34 is fixed at the output end of the push motor 33. The snap-fit ​​component 32 includes a perforated plate 321, which is horizontally slidably assembled on the rod 31. Two snap frames 322 are symmetrically and horizontally arranged on the front end face of the perforated plate 321, and multiple through holes 326 are horizontally opened on the top surface of each of the two snap frames 322.

[0032] By adopting the above technical solution, the bicycle frame requiring drilling is placed between two clamping frames 322, and then the clamping frames 322 are assembled at the opening of the clamping frame 322 on the hole plate 321. This ensures that the clamping and limiting bicycle frame remains stable during drilling. When drilling, the motor 2 on the processing table 1 is started to drive the rod 31 on the limiting component 3 to deflect, thereby causing the clamping and limiting bicycle frame to deflect at a suitable angle. This facilitates the later adjustment of the bicycle frame drilling angle. During drilling, the clamping and limiting bicycle frame is moved laterally by the horizontal sliding of the hole plate 321 on the rod 31, which facilitates the lateral movement of the clamping and limiting bicycle frame and the switching of the drilling position of the clamping and limiting bicycle frame. This allows for the lateral adjustment of the frame drilling position according to actual needs, reducing steps and improving the efficiency of frame drilling.

[0033] Reference Figure 3 and Figure 4One of the two card frames 322 has a horizontally formed slot 328 on its top surface, and the other card frame 322 has a horizontally fixed insert block 327 on its top surface, which slides into the slot 328. When the two card frames 322 are assembled together to limit and engage the frame, the insert block 327 slides into the slot 328 to facilitate assembly and guidance. One of the two card frames 322 has a horizontally fixed insert rod 323 on its lower side, and a horizontally through-hole is formed on the lower side of another card frame 322. The insert rod 323 and the screw hole fixed to the lower side of one of the two card frames 322 serve to guide the assembly of the two card frames 322 together laterally. Two clip frames 322 each have a horizontally penetrating insertion hole 325 on their lower side, through which a rod 323 is slidably inserted. A bolt 324 is rotatably connected horizontally through the other lower side of each clip frame 322, and the bolt 324 is threaded into a screw hole on the other clip frame 322. When the two clip frames 322 are assembled together, the rod 323 on one clip frame 322 is slidably inserted into the insertion hole 325 of the other clip frame 322. This horizontally guides and supports the assembly of the two clip frames 322. The bolt 324 on the rotating clip frame 322 is threaded into the screw hole of the other clip frame 322, thus locking and securing the bicycle frame and maintaining its stability.

[0034] Reference Figure 3 and Figure 4 A rotating bar 39 is vertically fixed to the vertical end face of the perforated plate 321 near the drive motor 33, and a rotating wheel 391 is horizontally rotatably connected to the end of the rotating bar 39. The rotating bar 39 on the perforated plate 321, rotatably connected to the rotating wheel 391, facilitates the later rotation of the perforated plate 321 to slide on the rod 31, changing the position of the opening in the bicycle frame. A spring 38 is horizontally fixed to the vertical end face of the other side of the perforated plate 321, and the other end of the spring 38 is fixed to the end of the rod 31. The spring 38, horizontally positioned between the perforated plate 321 and the rod 31, facilitates the use of the deformation force of the spring 38 to push the perforated plate 321 horizontally to slide back to its original position on the rod 31.

[0035] Reference Figure 3 and Figure 4Multiple helical tubes 35 are evenly and vertically arranged on the outer circumference of the push wheel 34, with one end of each helical tube 35 rotatably connected to the outer circumference of the push wheel 34. The multiple helical tubes 35 on the outer circumference of the push wheel 34 rotate on the push wheel 34, facilitating vertical adjustment of the bicycle frame opening position according to the desired opening position. A stud 36 is threaded into each helical tube 35, and an arc-shaped push block 37 is fixed to the outer end of the stud 36. According to the required opening position of the bicycle frame, rotating the helical tube 35 on the push wheel 34 pushes the stud 36 vertically within the helical tube 35. This allows the stud 36 to extend beyond the length of the helical tube 35, facilitating the activation of the push motor 33 to rotate the push wheel 34. This causes push blocks 37 of different lengths to press against the rotating wheel 391. The push blocks 37 of different lengths then push the perforated plate 321 on the rod 31 to slide horizontally, causing the clamped bicycle frame to move laterally, changing the horizontal opening position.

[0036] The implementation principle of a bicycle frame positioning fixture in this application embodiment is as follows: During use, the bicycle frame requiring drilling is placed between two clamping frames 322. The clamping frames 322 are then assembled at the opening of the clamping frame 322 on the perforated plate 321. When the two clamping frames 322 are assembled together, the insertion rod 323 on one clamping frame 322 slides through and is inserted into the insertion hole 325 of the other clamping frame 322. The horizontal guide supports the assembly of the two clamping frames 322. The bolt 324 on the rotating clamping frame 322 is threaded into the screw hole of the other clamping frame 322, thus locking and clamping the bicycle frame to maintain stability. This ensures the clamped and limited bicycle frame remains stable during drilling. Then, when drilling, according to the drilling requirements, the drilling angle is adjusted. The motor 2 on the processing table 1 is started, causing the rod 31 on the limiting component 3 to deflect, causing the clamped and limited bicycle frame to deflect at a suitable angle. The angle of the opening in the bicycle frame is adjusted laterally. According to the opening position requirements of the bicycle frame, the screw tube 35 is rotated on the push wheel 34, which pushes the stud 36 to move vertically in the screw tube 35. The length of the stud 36 extending out of the screw tube 35 facilitates the start of the push motor 33 to drive the push wheel 34 to rotate, which drives the push blocks 37 of different lengths to press against the rotating wheel 391. The push blocks 37 of different lengths push the hole plate 321 on the rod 31 to slide horizontally, which drives the clamped bicycle frame to move laterally to change the horizontal opening position. The spring 38 horizontally set between the hole plate 321 and the rod 31 facilitates the use of the deformation force of the spring 38 to push the hole plate 321 to slide horizontally on the rod 31 to return to its original position. When opening the hole, the hole plate 321 slides horizontally on the rod 31, and the horizontal sliding engagement limits the horizontal movement of the bicycle frame, which facilitates the horizontal movement and engagement limiting the opening position of the bicycle frame.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
