Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] like Figures 1 to 4 The directional handlebar assembly tooling shown includes a base plate 1 and a control valve 2, a vacuum generator 3, and an assembly platform 4 fixed thereon. The vacuum generator 3 is connected to the assembly platform 4 through an air pipe. The control valve 2 is connected to the vacuum generator 3 and the assembly platform 4 through an air pipe and supplies air to them respectively. The assembly platform 4 includes a support base 41 and a limiting sleeve 42 disposed thereon. The support base 41 is connected to the limiting sleeve 42 through its top positioning cylinder 411. An air intake hole 412 and an air blowing hole 413 are provided on the side wall of the positioning cylinder 411.

[0027] The base plate 1 serves as the mounting reference surface for the entire device, supporting core components such as the control valve 2, vacuum generator 3, and assembly platform 4. The control valve 2 includes a gas path switching hub, which is connected to the gas source, vacuum generator 3, and air blowing port 413 of the assembly platform 4 via air pipes to adjust the negative pressure state of the assembly platform 4. The vacuum generator 3 uses compressed air to generate negative pressure and connects to the suction port 412 of the assembly platform 4 via a vacuum interface to create a negative pressure environment inside it.

[0028] In this embodiment, an outer annular groove 414 is provided at the top of the positioning cylinder 411, and an inner annular groove 421 is provided at the bottom of the limiting sleeve 42. The limiting sleeve 42 is engaged with the outer annular groove 414 through the inner annular groove 421. The limiting sleeve 42 is detachably connected to the support base 41, making it convenient to select the appropriate limiting sleeve 42 and fit it with the plastic handle according to different sizes and orientations.

[0029] Furthermore, a sealing assembly 44 is provided at the connection between the inner ring groove 421 and the outer ring groove 414. The limiting sleeve 42 is slidably connected to the outer ring groove 414 through the inner ring groove 421. The sealing assembly 44 includes a plurality of urethane gaskets 441 sleeved on the outer ring groove 414.

[0030] By replacing the limiting sleeve 42 with different inner diameters to match the plastic grip specifications, and combining this with vacuum adjustment (controlling the opening of valve 2), precise control of the expansion amount can be achieved. The inner annular groove 421 of the limiting sleeve 42 slides into the outer annular groove 414 of the positioning cylinder 411, allowing for quick replacement of the limiting sleeve 42. Multi-layer urethane gaskets 441 can be selected to fill the gap between the inner annular groove 421 and the outer annular groove 414 with different thicknesses, compensating for dimensional changes caused by machining tolerances and temperature through elastic deformation, ensuring airtightness.

[0031] Furthermore, a handlebar end plug 43 is provided on the support base 41 at the axis of the positioning cylinder 411. The handlebar end plug 43 seals the tail hole while positioning the plastic handlebar, ensuring the airtightness of the cavity between the outer wall of the plastic handlebar and the inner wall of the limiting sleeve 42, and ensuring the stability of the negative pressure state during operation.

[0032] Furthermore, a first air pipe connector 45 is provided at the air blowing port 413, a second air pipe connector 31 is provided at the vacuum interface of the vacuum generator 3, a third air pipe connector 32 and a silencer 33 are provided at the air inlet and air outlet of the vacuum generator 3 respectively, a fourth air pipe connector 46 is provided at the air intake port 412, a fifth air pipe connector 21 and a sixth air pipe connector 22 are provided at the two air outlets of the control valve 2 respectively, and a seventh air pipe connector 23 is provided at the air inlet of the control valve 2; the first air pipe connector 45 is connected to the fifth air pipe connector 21, the second air pipe connector 31 is connected to the fourth air pipe connector 46, and the third air pipe connector 32 is connected to the sixth air pipe connector 22.

[0033] Specifically, compressed air is connected through the seventh air pipe connector 23, and the sixth air pipe connector 22 is connected to the air inlet of the vacuum generator 3 to drive the vacuum generator 3 to work; the second air pipe connector 31 is connected to the fourth air pipe connector 46 through an air pipe to establish a negative pressure drive channel; the fifth air pipe connector 21 is connected to the first air pipe connector 45 through an air pipe to form a positive air blowing channel; the silencer 33 is installed at the air outlet of the vacuum generator 3 to reduce exhaust noise.

[0034] During assembly, adjust the limiting sleeve 42 to an appropriate height so that the plastic handlebar sleeve is placed in the assembly base 4. The tail hole of the plastic handlebar sleeve should be in full contact with the tail plug 43 (if the tail plug has no hole, it should not be in contact), and the top of the plastic handlebar sleeve should be in contact with the top of the limiting sleeve 42. Open the control valve 2 to a suitable position, and the vacuum generator 3 will work to generate suction, creating a negative pressure inside the assembly base 4. After the top of the plastic handlebar sleeve is in close contact with the limiting sleeve 42, the mounting hole of the plastic handlebar sleeve will be enlarged under the action of negative pressure. At this time, the friction between the handlebar and the plastic handlebar sleeve will be greatly reduced, making assembly easier. After the handlebar is assembled, close the vacuum through the control valve 2 to tighten the plastic handlebar sleeve and remove the assembled handlebar sleeve from the tooling. If part of the handlebar sleeve is difficult to remove due to the vacuum negative pressure, the control valve 2 can be adjusted to the other control position to blow air into the air hole 413 of the assembly base 4 to release the negative pressure and facilitate the removal of the handlebar. The enlargement of the mounting holes for plastic grips is closely related to the material of the grips. The harder the plastic grip, the greater the negative pressure value required from the vacuum generator 3.

[0035] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
