Description

Technical Field

[0001] The invention relates to wheel rim processing equipment, in particular to a drilling device for a wheel rim with spokes. Background Art

[0002] Wheel rims, also called hubs, are generally called hubs for automobiles. Some of the rims used on motorcycles, electric bicycles, and bicycles have spokes. Spokes are the thin and long metal rods on the rims. Using spokes to connect can reduce the weight of the wheel, save material costs, and also play a certain role in elastic deformation. Rims with spokes generally require inner tubes in the tires, which are inflated to meet driving requirements. In order to connect the spokes to the rims, the technical solution adopted is to set a number of through holes on the rims, and the spokes pass through the through holes with one end buckled on the inner rim wall, and the other end of the spokes is connected to the hub and tightened. Wheel rims of different specifications have different widths and wall thicknesses, and their corresponding hub parameters are also different. Therefore, the axis of the spoke holes on the wheel rim does not necessarily pass through the axis of the wheel rim. These spoke holes may be tilted to a certain extent. If the spoke holes of the wheel rim are not processed accurately enough, or the relative positions of the spoke holes are incorrect, it will cause installation difficulties. If the spokes are installed forcibly, the spokes will be bent to a certain extent at the connection. During use, the connection between the spokes and the wheel rim will produce a large stress. On the one hand, the strength of the wheel rim is deteriorated and the bearing capacity is reduced. On the other hand, this shear stress is likely to cause damage to the wheel rim and lead to scrapping. At present, when drilling the spoke holes of the wheel rim, the drilling machines on the market either have large deviations, that is, the exit position of the actually drilled hole, the extension direction of the hole, etc. are not correct, or the adjustment is particularly cumbersome and the processing is very inconvenient. Therefore, the present invention is developed under such a background. Summary of the invention

[0021] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0022] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, an indirect connection through an intermediate medium, or the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0024] The present invention provides a drilling device for a wheel rim with spokes. In one embodiment, the drilling device for a wheel rim with spokes comprises: a support, which is configured as a supporting component for mounting the wheel rim; a frame, which is located at one side of the support; a feed support plate is provided on the frame, and a drill rotation driving component is provided on the feed support plate; a feed driving mechanism is used to drive the drill on the drill rotation driving component to advance or retract along a guide component; the feed support plate is provided with a first circular arc matching portion, and the frame is provided with a second circular arc matching portion that matches the first circular arc matching portion, and under the action of external force, the first circular arc matching portion can slide along the circular arc path defined by the second circular arc matching portion, so that the drill rotation driving component can swing relative to the wheel rim on the support; the projection of the center of the circle corresponding to the circular arc path on the radial cross section of the wheel rim is located in the area surrounded by the outer diameter of the wheel rim; a swing locking component is used to lock or unlock the feed support plate.

[0025] In the present invention, a purpose is to enable the drill bit rotation driving component to rotate around a preset axis, and the preset axis is a virtual axis. According to the relative position of the drill bit rotation driving component, the virtual axis will also change accordingly. When an object needs to rotate around a point, there are two ways. The first way is to set an actual rotating shaft, which is connected to the object. At this time, if there is a driving force (including gravity), the object can rotate around the axis of the rotating shaft; the other way is to set an arc trajectory for the object. Under the driving force, the object can rotate on the arc trajectory around the virtual rotation axis. If the relative position of the arc trajectory changes, the corresponding center of the circle will also change. According to actual needs, on the contrary, if the position of the virtual center of the circle is set, the arc trajectory is also determined.

[0026] As is known to all, wheel rims of different sizes and used in different products have different specifications. Therefore, during the production and processing of wheel rims, the positions where holes need to be drilled are also different. That is to say, if the holes are drilled using the first method, an offset will occur, making it difficult to meet the processing requirements of the product. The present invention uses the principle of the second method to drill holes. When the specifications of the wheel rim are determined, the virtual center of the circle in the second method is determined. At this time, it is only necessary to adjust the relative position of the arc trajectory in the second method to match the virtual center of the circle. In view of this, as long as the drilling is carried out using principles substantially the same as those of the present invention to achieve substantially the same effect, it should be considered an equivalent replacement of the present invention.

[0027] As a preferred embodiment, the swinging of the feed support plate relative to the frame along the arc path is up and down swinging, and the frame is provided with an adjustment component for adjusting the height of the feed support plate.

[0028] As another preferred embodiment, a fan ring plate is provided on the feed support plate, and a plurality of rollers are provided on the frame for respectively abutting against the outer arc side and the inner arc side of the fan ring plate; the center of the fan ring plate is located on the wheel rim installed on the support.

[0029] As another preferred embodiment, a clamp is provided on the support for clamping the wheel rim, and a rotation drive mechanism is also provided on the support for driving the wheel rim to rotate around its axis.

[0030] As another preferred embodiment, a height adjustment plate is provided on the frame, the fan ring plate is connected to the height adjustment plate, a height adjustment transmission screw is provided on the frame, a transmission nut is provided on the height adjustment plate, the height adjustment transmission screw is cooperatively connected with the transmission nut, and the height of the fan ring plate is adjusted to match wheel rims of different specifications.

[0031] As another preferred embodiment, there are four rollers, two of which are located on the outer arc side of the fan ring plate, and two are located on the inner arc side of the fan ring plate. The four rollers cooperate with the arc surface of the fan ring plate through their circumferential surfaces.

[0032] As another preferred embodiment, a tool setting reference axis is provided on the frame, and the axis centerline of the tool setting reference axis intersects with the axis centerline of the drill bit on the wheel rim and matches with the hole position to be drilled on the wheel rim.

[0033] As another preferred embodiment, the drill bit is mounted on an electric spindle, and the electric spindle is mounted on a feed support plate and connected to a feed drive mechanism.

[0034] As another preferred embodiment, a scale for adjusting the angle is provided between the height adjustment plate and the fan ring plate.

[0035] The present invention will be further described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0036] refer to Figure 1-3 As shown, a drilling device for a spoke wheel rim includes a base 11, a horizontal swing angle base plate 12 is provided on the base 11, a front and rear adjusting screw 10 is provided on the base 11, and a threaded component (not shown) matching with the front and rear adjusting screw 10 is provided on the horizontal swing angle base plate 12, so that when the front and rear adjusting screw 10 rotates, the horizontal swing angle base plate 12 is driven to move forward and backward through the threaded component matching therewith.

[0037] A horizontal swing angle rotating plate 16 is installed on the upper side of the horizontal swing angle base plate 12. Specifically, the horizontal swing angle rotating plate 16 is pivotally connected to the horizontal swing angle base plate 12 through the tool setting reference axis 17, that is, the horizontal swing angle rotating plate 16 can swing left and right relative to the horizontal swing angle base plate 12 with the axis center of the tool setting reference axis 17 as the swing axis center.

[0038] The support vertical plate 5 is installed on the horizontal swing angle rotating plate 16 , and the support vertical plate 5 moves or swings along with the horizontal swing angle rotating plate 16 .

[0039] A height adjustment plate 2 is movably mounted on the support vertical plate 5 via a guide rail component. Specifically, a height adjustment screw 4 is provided on the support vertical plate 5, and a threaded component (not shown) matching the height adjustment screw 4 is provided on the height adjustment plate 2. In this way, when the height adjustment screw 4 rotates, the height adjustment plate 2 moves up and down through the threaded component matching therewith.

[0040] Four rollers 13 are provided on the height adjustment plate 2, and the four rollers 13 are arranged in a fan ring shape. The fan ring plate 3 is clamped between the four rollers 13, that is, two of the four rollers are located on the outer arc side of the fan ring plate 3, and two are located on the inner arc side of the fan ring plate 3. The four rollers 13 cooperate with the arc surface of the fan ring plate 3 through their circumferential surfaces, and the rollers 13 are movably installed on the height adjustment plate 2 through roller shafts 14 so that they can rotate.

[0041] The other side of the fan ring plate 3 is fixedly mounted on a feed support plate 1, so that when the fan plate 3 swings up and down along the arc track defined by the four rollers 13, the feed support plate 1 also swings along with it. To facilitate the swinging of the fan ring plate 3, an adjusting screw can be provided on the feed support plate 1, one end of the adjusting screw is threadedly connected to the shaft head hinged on the fan ring plate, and the other end of the adjusting screw is connected to the shaft head hinged on the feed support plate 1. When the adjusting screw rotates, the adjusting screw drives the shaft head to move. Since the shaft head is hinged to the fan ring plate, no interference occurs when the fan ring plate rotates.

[0042] A drive motor 19 is installed on the feed support plate 1, and the drive motor 19 is transmission-connected to the electric spindle 7, and a drill bit 20 is installed on the electric spindle 7. Specifically, a slide rail is provided on the feed support plate 1, and a resistance shaft mounting seat 6 is installed on the slide rail. The electric spindle 7 is fixedly installed on the resistance shaft mounting seat 6. When the drive motor 19 drives the resistance shaft mounting seat 6 to move, it drives the drill bit 20 to move to realize feed or retract.

[0043] A support 18 is provided on one side of the base 11, and a clamp 9 is installed on the support 18. During processing, the rim 8 is fixed on the support 18 by the clamp 9. The clamp is of multiple specifications and can match rims of different sizes.

[0044] The fan ring plate 3 is provided with an adjustment handle 15, through which the position of the fan ring plate 3 on the height adjustment plate 2 can be adjusted. In order to facilitate intuitive observation of the adjusted angle α, a scale for adjusting the angle is provided between the height adjustment plate and the fan ring plate. In this way, the value of α can be quickly set according to each batch of rims to be processed.

[0045] In this embodiment, a swing guide limit groove 21 is provided on the horizontal swing angle bottom plate 12. The swing guide limit groove 21 is in an arc shape, and its center is located on the axis of the tool reference axis 17. A limit portion is provided on the horizontal swing angle rotating plate 16 to be inserted into the limit groove 21. Through the cooperation between the limit portion and the limit groove 21, on the one hand, the swing of the horizontal swing angle rotating plate 16 can be made more stable, and on the other hand, the guiding and limiting functions can be achieved.

[0046] In this embodiment, the radius of the fan ring plate 3 intersects with the axis of the tool reference axis 17 at a point, which happens to fall on the inner surface of the rim where the spoke hole is located. In this way, any angle α of the fan ring plate 3 and any angle β of the horizontal swing angle rotating plate 16 will not cause the deviation of the spoke hole exit position, thereby ensuring the correctness of the spoke hole position. Of course, not every specification of rim needs to adjust both the α angle and the β angle at the same time, and only one of them can be adjusted.

[0047] In this embodiment, a rotation drive mechanism (not shown) is also provided on the support 18 for driving the wheel rim 8 to rotate around its axis. In this way, when one spoke hole is processed, the wheel rim 8 rotates by a preset angle to continuously process the second spoke hole.

[0048] The working process of the present invention is: according to the size and width of the wheel rim, the number of holes to be drilled and the drilling angle, the processing mode of the corresponding wheel rim model is called out from the human-computer interaction interface (not shown, it can be a screen), and the height position of the height adjustment plate 2, the wheel rim size position on the fixture 9, the upper and lower swing angle positions of the fan ring plate 3, the horizontal swing angle position of the horizontal swing angle rotating plate 16, and the horizontal position of the horizontal swing angle base plate 12 are manually adjusted on the equipment according to the processing mode. When the parameters are adjusted to be the same as those displayed on the human-computer interaction interface, the workpiece can be automatically processed.

[0049] As another embodiment of the present invention, different from the first embodiment, a fan ring plate or a fan ring groove is provided on the feed support plate, and correspondingly, a fan ring groove or a fan ring plate is provided on the frame, and the fan ring plate is clamped in the fan ring groove. In this way, the feed support plate can also swing relative to the frame along the arc path defined by the first arc matching portion and the second arc matching portion.

[0050] The drilling device of the present invention is not only convenient for processing spoke holes, but also convenient for processing other holes on the rim, such as valve holes, because valve holes generally do not have compound angles, so it is simpler.
