Abstract
Description
Technical Field
[0001] This utility model relates to the field of handlebar processing, specifically a positioning device for handlebar processing. Background Technology
[0002] In the manufacturing process of non-motorized vehicle frames and handlebars, precise drilling of tubular handlebars is often required. These handlebars are often irregularly curved, and different vehicle models require handlebars of different sizes. Before drilling, a positioning device must be used to ensure the accurate position of the handlebar. Subsequently, tools such as a drilling gun are used to drill holes in the tubular handlebars.
[0003] However, when performing drilling operations, existing drilling positioning devices usually use horizontal positioning of the riser for drilling. This not only requires higher precision to ensure the relative positional relationship between the holes, but also if the horizontal positioning is inaccurate or unstable, it may cause the riser to shake or shift during the drilling process, affecting the drilling quality.

[0025] like Figure 1-4 As shown, a positioning device for handle processing is installed on a worktable 1, including a handle center positioning assembly and at least two sets of handle tube positioning assemblies 4, wherein...
[0026] The handle center positioning assembly includes a pole assembly 2 and a pole center positioning component 3. The pole assembly 2 includes a center positioning post 2-1 and two center positioning brackets 2-2. The center positioning post 2-1 is vertically mounted on the workbench 1 for inserting the center tube 5-1. The two center positioning brackets 2-2 are symmetrically arranged on both sides of the center positioning post 2-1, and the top of the center positioning bracket 2-2 is a ramp structure. The inclined surface of the ramp 2-21 matches the contour of the handle 5. The pole center positioning component 3 includes a positioning rod 3-1, a positioning push block 3-2, and a pushing assembly 3-3. The positioning push block 3-2 is located at the output end of the pushing assembly 3-3. The positioning rod 3-1 is located at the front end of the positioning push block 3-2. The pushing assembly 3-3 drives the positioning rod 3-1 on the positioning push block 3-2 to pass through the positioning holes on the center tube 5-1 and the center positioning post 2-1 in sequence. The horizontal center axis of the positioning rod 3-1 intersects perpendicularly with the center axis of the center positioning post 2-1.
[0027] Two sets of handle tube positioning components 4 are symmetrically arranged on both sides of the handle center positioning component, and are used to position the handle tubes 5-2 at both ends of the handle.
[0028] In this invention, the top of the central positioning bracket 2-2 contacts the handle via a ramp structure, providing lateral support to ensure the stability of the handle's central tube 5-1 when vertically inserted into the central positioning post, preventing offset or tilting caused by the handle's irregular shape. Simultaneously, the central positioning bracket 2-2 and the central positioning post 2-1 together form a "three-point support" system. The central positioning post provides axial positioning in the vertical direction, while the two side central positioning brackets 2-2 constrain the handle's lateral freedom through the ramp structure, preventing the central tube from shaking due to force during drilling, thereby improving positioning accuracy.
[0029] In this embodiment 1, each handle tube positioning assembly 4 includes a handle tube positioning bracket 4-1, a limiting block 4-2, and a clamping assembly 4-3. The handle tube positioning bracket 4-1 is set on the workbench 1, and the top of the handle tube positioning bracket 4-1 is provided with a handle tube positioning groove 4-13 for placing the handle tube 5-2. The limiting block 4-2 is set at the handle tube positioning groove 4-13 at the top of the handle tube positioning bracket 4-1 for limiting the end of the handle tube 5-2. The clamping assembly 4-3 is installed on the positioning bracket 4-11, and the clamping assembly 4-3 drives the clamping block 4-31 to abut against the handle tube 5-2 to provide clamping force for positioning the handle tube 5-2.
[0030] In this invention, a limiting block 4-2 is set at the handle tube positioning groove 4-13 (near the end) at the top of the handle tube positioning bracket 4-1, thereby constraining the lateral displacement of the handle tube and eliminating the risk of tube movement during processing.
[0031] In this utility model, the clamping block 4-31 applies clamping pressure to the handle tube 5-2, rigidly pressing the handle tube 5-2 into the handle tube positioning groove 4-13. This not only provides stable positioning but also forms a "three-point linkage locking" with the handle center positioning component, reducing drilling vibration and improving drilling accuracy.
[0032] In this embodiment 1, the handle tube positioning bracket 4-1 includes two positioning brackets 4-11, and a connecting bracket 4-12 is installed between the two positioning brackets 4-11 to ensure that the center line of the handle tube positioning groove 4-13 of the two positioning brackets 4-11 overlaps or is parallel to the central axis of the handle tube 5-1.
[0033] In this embodiment 1, the positioning push block 3-2 abuts against the central tube 5-1 of the handle 5, and the abutting surface of the positioning push block 3-2 is set according to the contact surface of the central tube.
[0034] In this utility model, the center positioning component of the upright can be equipped with a positioning push block 3-2 according to the actual needs of the handle to be processed. For example... Figure 1 As shown, a gasket needs to be welded to the positioning hole of the central tube 5-1, such as... Figure 5 As shown, a cladding piece needs to be welded at the positioning hole of the central tube 5-1. The abutting surface of the positioning push block 3-2 is set according to the actual contact surface, serving as a positioning pad or cladding piece for precise welding. The center positioning component of the upright can be positioned in front of or behind the handle tube, as required by those skilled in the art.
[0035] In this embodiment 1, the pushing component is a push-pull quick clamp, and the clamping component is a vertical quick clamp. These quick clamps are all existing standard parts and therefore are not described in detail. Those skilled in the art can also use existing driving components such as cylinders or electric push cylinders to drive the pushing component and clamping component according to actual needs.
[0036] In this utility model, in order to reduce the friction between the positioning push block 3-2, the clamping block 4-31 and the handle, the positioning push block 3-2 and the clamping block 4-31 can be made of elastic materials, such as rubber blocks.
[0037] The working principle of this utility model is as follows:
[0038] Initial positioning: Insert the handle center tube 5-1 vertically into the center positioning post 2-1 of the pole assembly, and at the same time place the handle tubes 5-2 at both ends into the positioning slots 4-13 of the positioning bracket 4-1.
[0039] Axial locking: The positioning rod 3-1 on the control positioning push block 3-2 moves towards the central tube 5-1, so that the positioning rod 3-1 passes through the positioning holes of the central tube 5-1 and the central positioning post 2-1 in sequence, thereby positioning the handle central tube axially and eliminating the risk of axial up and down movement.
[0040] Pipe end reinforcement: Control the tightening component 4-3, press the handle pipe 5-2 with the tightening block 4-31, and combine with the limit block 4-2 to constrain the end displacement, forming a stable positioning system.
[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
