Description

Technical Field

[0001] The utility model relates to the technical field of billiard cue maintenance, in particular to a tool fine-tuning mechanism and a cue repair machine. Background Art

[0002] In the process of using the cue, in order to adapt to the needs of different players, the cue often needs to be properly ground. Moreover, the tip of the billiard cue is easily worn during use, so it needs to be repaired or replaced in time according to the usage. Manual repair is extremely tedious, so the cue repair machine came into being.

[0003] Existing cue stick trimming machines usually include a base with a guide rail, on which a slider bearing seat, a clamping mechanism, a tool fine-tuning mechanism and a tailstock are installed in sequence. The slider bearing seat fixes the tail of the billiard cue, and the clamping mechanism includes a main shaft, a main shaft pulley, a main shaft seat and a three-jaw chuck. The clamping mechanism usually needs to be used in conjunction with a transmission mechanism and a motor. The main shaft pulley is connected to the motor pulley on the motor through a belt. The billiard cue is clamped in the three-jaw chuck, and the motor drives the billiard cue to rotate at high speed; the tool fine-tuning mechanism is used to adjust the axial and radial position of the tool holder, which is convenient for fine grinding of the front end of the billiard cue; the tailstock is used to support the replaced leather tip through the drill chuck at the end when the leather tip is replaced, so that the leather tip and the billiard cue are more firmly bonded.

[0004] The tool fine-tuning mechanism achieves radial movement through the screw structure between the upper support plate and the lower support plate, and the screw shaft structure also needs to cooperate with the radially arranged dovetail groove to achieve precise movement and positioning. The existing problem is that the assembly of the dovetail groove and the trapezoidal slider has very high precision requirements, and it is easy to get stuck when the dovetail groove is directly installed. Utility Model Content

[0005] The purpose of the utility model is to address the shortcomings of the existing technology, namely the problem that jamming easily occurs when the dovetail groove is directly assembled, and to provide a tool fine-tuning mechanism for adjusting the flatness and fit between the dovetail groove and the trapezoidal slider, and a rod trimming machine using the tool fine-tuning mechanism.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a tool fine-tuning mechanism, including a screw transmission structure, the screw transmission structure includes an integrally formed upper support plate and an integrally formed lower support plate, the top of the lower support plate is provided with a radial dovetail groove, a strip is inserted into the dovetail groove, and a plurality of bolt holes are distributed on the strip, and a trapezoidal slider is provided at the bottom of the upper support plate corresponding to the dovetail groove and the strip, the upper support plate is provided with a plurality of side holes, the side holes pass through the trapezoidal slider, the side holes correspond to the bolt holes one by one, bolts are provided to connect the trapezoidal slider and the strip, the middle of the lower support plate is hollowed out and a screw nut moving groove is formed, the groove walls at both ends of the screw nut moving groove are opened and ball bearings are provided, a screw shaft is provided to radially pass through the screw nut moving groove and be installed in the ball bearing, the bottom of the upper support plate is fixedly connected to the screw nut, and one end of the screw shaft extends and is connected to a radial handwheel. It needs to be further explained that the upper support plate is integrally formed with a trapezoidal slider, and the lower support plate is integrally formed with a dovetail groove. The upper support plate serves as both a support plate and a slider, and the lower support plate serves as both a support plate and a guide rail. When installing the upper support plate and the lower support plate, due to the high matching accuracy requirements of the dovetail groove, direct assembly is prone to jamming, resulting in time-consuming and labor-intensive. A gap is set between the dovetail groove and the trapezoidal slider and an inlay is assembled. Bolts are installed in the side holes to match the bolt holes on the inlay. The gap between the inlay and the dovetail groove is adjusted by the bolts, which facilitates installation and better adjusts the flatness and fit between the dovetail groove and the trapezoidal slider.

[0007] Preferably, a gear hanging plate is vertically connected to the bottom of the lower support plate, and an axial handwheel is radially inserted into the gear hanging plate. The axial handwheel passes through one end of the gear hanging plate and is connected to a transmission gear set. The transmission gear set includes a first gear mounted on the axial handwheel, and the first gear meshes with a double gear. It should be further explained that to facilitate manual operation, the axial handwheel is positioned below and to the left of the radial handwheel, and the right hand controls the radial handwheel to improve operational accuracy.

[0008] Preferably, the bottom of the lower support plate is connected to a slide locking plate, a knob rod is radially passed through the slide locking plate, the head of the knob rod is connected to a plum blossom knob, and the tail of the knob rod is provided with a slider top plate. It should be further explained that, in order to further facilitate manual operation, the plum blossom knob is arranged to the right of the radial handwheel. During operation, the left hand operates the axial handwheel to adjust the distance of the tool fine-tuning mechanism relative to the linear guide, and the right hand operates the plum blossom knob. The plum blossom knob pushes the slider top plate toward the linear guide via the knob rod, thereby fixing the position of the tool fine-tuning mechanism on the linear guide.

[0009] Preferably, a tool holder is provided at the upper end of the upper support plate.

[0010] Preferably, the bottom of the lower support plate is axially connected with a support plate slider.

[0011] Preferably, a rod trimming machine using the tool fine-tuning mechanism also includes a linear guide rail, a rectangular tube base, a slider bearing seat, a clamping mechanism, a transmission mechanism, a motor, and a tailstock. The tailstock includes an upper tailstock and a lower tailstock. The lower tailstock is provided with a tailstock dovetail groove, and a gasket is inserted into one side of the tailstock dovetail groove. The upper tailstock is provided with a tailstock trapezoidal slider corresponding to the tailstock dovetail groove and the gasket. The upper tailstock has a hole corresponding to the tailstock trapezoidal slider and is installed with a tailstock bolt. It should be further explained that the radial position of the tailstock is adjusted by the dovetail groove structure, and the jamming phenomenon of the upper tailstock when directly installed is avoided by providing a gasket inserted into the tailstock dovetail groove. The radial position of the upper tailstock is locked by controlling the gasket through the tailstock bolt.

[0012] Preferably, the rectangular tube base is equipped with a controller, an emergency stop switch, a drag chain, and a rack. The drag chain is connected to the motor, and a cable is connected to the inside of the drag chain. The cable is arranged in the rectangular tube base and connected to the controller. The clamping mechanism is connected to a potentiometer. It should be further explained that the cable is protected by the drag chain, and the controller and emergency stop switch are installed in the rectangular tube base, and the potentiometer is installed in the clamping mechanism. The potentiometer controls the rotation speed of the three-jaw chuck in the clamping mechanism, thereby controlling the rotation speed of the billiard cue and improving operational accuracy.

[0013] Preferably, the rack is mounted vertically downward, meshing with the corresponding double gears, and a baffle is provided above the rack. It should be further noted that in actual use, when the rack is mounted in the forward direction, sawdust from grinding will splash onto the rack, requiring the operator to constantly clean the sawdust from the rack to prevent the axial handwheel from getting stuck. The baffle is installed and the rack is mounted vertically downward to prevent sawdust from splashing.

[0014] Compared with the prior art, the present invention has the following advantages: by arranging a detachable insert in the dovetail groove and controlling the flatness and fit between the insert and the dovetail groove by bolts, the installation of the upper support plate and the lower support plate is facilitated, and the cooperation between the dovetail groove and the trapezoidal slider is smoother.
