Description

VERTICAL RIM TRIMMING MACHINE 1. Field of the Invention I’he present invention relates to a rim trimming machine, especially to a vertical rim trimming machine. 2. Description of the Prior Arts
With referenced to Fig. 6, a conventional rim trimming machine 90 comprises a base 91, a monniiiig wall 92, a horizontal sliding element 93, a horizontal sliding stand 94, a vertical sliding element 95, a vertical sliding stand 96, a cntter tnrrei 97, and a fixture 98. The mounting wall 92 is connected to a rear surface of the base 91. The horizontal sliding element 93 is transversely hung on a top end of the mounting wall 92, and the horizontal sliding stand 94 is mounted on and is horizontally movable with respect to a front surface of the horizontal sliding element 93, such that the horizontal sliding stand 94 is horizontally disposed above the base 91. The vertical sliding element 95 is securely mounted on a front surface of the horizoiital sliding stand 94, and the vertical sliding stand 96 is mounted on and is vertically movable with respect to a front surface of the vertical sliding element 95, and the cutter turret 97 is securely mounted on a bottom end of the vertical sliding stand 96, such that the cutter turret 97 is horizontally and vertically movable with respect to the base 91 by the horizontal sliding stand 94 and the vertical sliding element 95. The fixture 98 is mounted on a top snrface of the base 91, and is disposed below the horizontal sliding element 93 correspondingly. The fixture 98 is connected to an actuator (not showui in the figure), such that the fixture 98 is horizontally rotatable with respect to the base 91. llie fixture 98 is for clamping a rim 80, such that the cutter turret 97 irims the rim 80 via a cutter (not shown in the figure).
How'ever, because the horizontal siiding element 93 is hung on the top end of the mounting wail 92, when the horizontai sliding stand 94 moves horizontally, the horizontal siiding stand 94 has to bear the vertical sliding element 95, the vertical sliding stand 96, and the cutter turret 97, which increases the loading of the horizontal sliding element 93 and makes the rigidity of the horizontal sliding element 93 inadequate. Therefore, the horizontal sliding stand 94 may easily shake with respect to the horizontal sliding element 93 when the cutter of the cutter turret 97 trims the rim 80. In addition, a vertical length of the vertical sliding element 95 is limited, such that when the vertical sliding stand 96 is moved downward to the lowest position relative to the vertical sliding element 95, a bottom end of the vertical sliding stand 96 may partially protrude and be exposed out of the vertical sliding element 95 without support, Thai is, the vertical sliding element 95 carmot provide the abutting force to the vertical sliding stand 96 such that the cutter ttJiret 97 may easily shake with respect to the rim 80 when the cutter turret 97 trims the rim 80 via the cutter, and the shake decreases the accuracy of trimming. Thus, the conventional rim trimming machine should be improved. Ίο overcome the shortcomings, the present invention provides a vertical rim trimming machine to mitigate or obviate the aforementioned problems.
The main objective of the present invention is to provide a vertical rim trimming machine which solves the problems generated by the conventional rim trimming machine which has a horizontal sliding element transversely hung on a top end of a mounting wall such that a horizontal slidin| stand has to bear a vertical sliding element, a vertical sliding stand and a cutter turret, which causes the defect that the horizontal sliding stand easily shakes with respect to the horizontal sliding element when a cutter of a cutter turret is trimming a rim. The vertical rim trimming machine of the present invention also solves tlie problems generated by the conventional rim trimming machine which has the vertical sliding element with limited length such that when the vertical sliding stand is moved downward to the lowest position, the bottom end of the vertical sliding stand may paitially protrude and be exposed out of the vertical sliding element without support, which makes tlie cutter of the cutter mrret shake easily and decrease the accuracy of trimming. Therefore, the present invention provides the vertical rim trimming machine which comprises a horizontal sliding stand which is mounted on and capable of horizontally moving with respect to a top surface of a base, a vertical sliding stand which is mounted on and is vertically movable with respect to a front surface of the horizontal sliding stand, and a rear surface of the vertical sliding stand which keeps connecting with and does not separate from the front surface of the horizontal sliding stand for providing an abutting force which the vertical sliding stand needs, so that the structure of the present invention may be fmner and the stability of trimming a rim via the cutter turret is improved.
The vertical rim trimming machine comprises; a base comprising; two first axial channels mounted on a top surface of the base and parallel to and spaced from each other; a first axial actuator mounted on the top surface and a lateral surface of the base and at one end of the first axial channels, and a first axial threaded shaft moimted on the top surface of the base and between the two first axial channels and connected with the first axial actuator for controlling a rotating direction of the first axial threaded shaft via the first axial actuator; a horizontal sliding stand uprightly mounted on the top surface of the base and horizontally movable with respect to the base, a bottom surface of the horizontal sliding stand mounted across on the two first axial channels of the base; the horizontal sliding stand comprising: a first axial threaded sleeve mounted on the bottom surface of the horizontal sliding stand and screwed with the first axial threaded shaft; tw'o second axial channels mounted on a front surface of the horizontal sliding stand and parallel to and spaced from each other; a second axial actuator mounted on the front surface and at a top end of the horizontal sliding stand; and a second axial threaded shaft mounted on the front surtace of the horizontal sliding stand and between the t\¥o second axial channels, and connected with the second axial actuator for controlling a rotational direction of the second axial threaded shaft via the second axial actuator; a vertical sliding stand mounted on the front surface of the liorizontal sliding stand and vertically movable with respect to the horizontal sliding stand, and a rear surface of the verb cal sliding stand mounted across on the (wo second axial channels of the horizontal sliding stand and connecting with the front surface of the horizontal sliding stand; the vertical sliding stand comprising a second axial threaded sleeve mounted on the rear surface of the vertical sliding stand and screwed with the second axial threaded shaft; a cutter tarret mounted on a front surface of the vertical sliding stand, and comprising a cutter securely mounted on the cutter turret; a bottom stand mounted on a front surface of the base: and a fixture mounted a top surface of the bottom stand.
The aforesaid vertical rim trimming machine, wherein the bottom simid comprises: a motor mounted on the top surface of the bottom stand and connected with the fixture so that the fixture is horizontally rotatable with respect to the bottom stand.
The aforesaid vertical rim trimming machine, wherein the fixture comprises: a plurality of jaws mounted on a top surface of the fixture.
The advantages of the present invention are; 1. The present invention provides an abutting force w^ich the vertical sliding stand needs through the horizontal sliding stand mounted on the top surface of the bottom stand and horizontally movable with respect to the bottom stand, the veitica! sliding stand mounted on the front surface of the horizontal sliding stand and vertically movable with respect to the horizontal sliding stand, and the rear surface of the vertical sliding stand connecting to the front surface of the horizontal sliding stand without separating, llius, the horizontal sliding stand is horizontally movable with respect to the bottom stand stably, and the vertical sliding stand is also vertically movable with respect to horizontal sliding stand stably. Compared to the conventional rim trimming madiine w'hich has the horizontal sliding element hiin| on a top of the momiiing wall, causing the defect that the horizontal sliding stand may easily shake with respect to the horizontal sliding element when the cutter turret trims the rim, the stracture of the present invention may be flnner and the stability^ of trimming a rim via the cutter tuhret is improved. 2, The present invention has the horizontal sliding stand which is capable of supporting the vertical sliding stand when the vertical sliding stand moves downward to the lowest position relative to the horizontal sliding stand. The conventional rim trimming machine has a defect that decreases the accuracy of trimming because the conventional rim trimming machine has the vertical sliding element with limited length, which causes that the bottom of the vertical sliding stand may be suspending with respect to the vertical sliding element w'hen the vertical sliding stand mo^ds downward to the Iciwest posilion relative to the vertical sliding element and the vertical sliding element cannot provide the abutting force w%ich the vertical sliding stand needs. Compared to the conventional rim trimming machine, the present invention provides the abutting force to the vertical sliding stand through the horizontal sliding stand uprightly mounted on the top surface of the bottom stand and makes the rear surface of the vertical sliding stand keep connecting with the front surface of the horizontal sliding stand without separating. Thus, the present invention improves the accuracy of the vertical movement of the vertical sliding stand.
