Description
- (a) Field of the Invention
- The invention is related to a tool holder transmission structure of a stone chamfering machine which is mainly characterized in that a tool holder which can be operated to rotate is installed on a convex block of a side plate which is located at one end of the stone chamfering machine, whereby the tool holder can be positioned by an elastic lockpin which is preset on one side of the side plate Further, the tool holder and the frame can be completely matched when pushed by the compacting plate handle whereby the bottom driven gear of the multi-axis tool installed on the tool holder can be engaged with the transmission gear of the motor inside the Frame. Therefore, it is particularly useful to select different tools for stone chamfering operation according to practical needs, thereof to improve the inconveniences and disadvantages of changing tools in the conventional one-tool type machines.
- (b) Description of the Prior Art
- Generally, for overall appearance and to avoid accidents from sharpened edges of cut stones, the stone edges are usually chamfered to provide a nicer outlook and a better safety.
- Most of the stone edge chamfering work is done by using a special purpose stone chamfering machine, whereby through reciprocating the stone chamfering machine and the transmission of inside installed motor to grind the tool to achieve the chamfering function.
- Whereas, the structure design of the conventional stone chamfering machine is usually of the embodiment of “one tool-one motor” to achieve stone edges chamfering function. Under this embodiment, in case there are different specifications of stones or operation requirements for different grinding roughness, the tool replacement is necessary. The original tool is dismounted and replaced with a suitable tool, and then if there is a different operation requirement, the tool replacement will have to be repeated again. As such, it causes a lot of man hours loss and inconveniences while several sets of tools must also be prepared at the same time, and each tool need to be saved in special purpose storage boxes for easy carry that is also troublesome and inconvenient. Especially, if the tool is not saved in the storage box after replacement directly, it is easy to have a tool lost problem that may result in the case when a tool of particular specification is needed but cannot be found, and consequently the operation is seriously affected and an additional cost of re-purchase is generated, therefore this situation is hardly ideal and improvements are necessary.
- Regarding the numerous problems and disadvantages of the conventional one-tool stone chamfering machine application, the inventor based on his many years of experience and skills in the related business has researched and developed the tool holder transmission structure of the invention, whereof it is mainly purposed to equip the stone chamfering machine with multiple tools of different specifications through the combination of structure designs thereby to provide a linkage transmission function which allows a suitable tool to be fetched corresponding to different operation requirements through a proper selection and change process.
- Another purpose of the invention is to provide a simple operation for the tool change operation on the stone chamfering machine and to obtain an ideal transmission linkage function through the assembly design of structure, i.e. the main purpose of the invention is through the multi-axis tool holder design to achieve quick and simple tool change corresponding to different operation requirements while avoids troubles and inconveniences in repeatedly mounting/dismounting tools in the conventional structures and avoids the needs to carry or reserve the tool storage boxes. Further, the tool lost problem is less likely to happen. Therefore, it is particularly capable to provide good application and usefulness to the industry.

- Please refer to the structural schematic drawing in
FIG. 1 , the partial explosion of structure explosion view inFIG. 2 , and the structure relation schematic drawings inFIGS. 3˜7 for a preferred embodiment of the invention; - As illustrated in the drawing, the structure design of the stone chamfering machine of the invention is mainly comprised of a
frame 10, inside which atransmission motor 20 is installed. Atransmission gear 21 is installed on the spindle of the saidtransmission motor 20, whereof the saidtransmission gear 21 has one end exposed outside throughSide Plate 30 of theframe 10 and forms a motion linkage by engaging with the drivengear 60 oftool 50 installed on thetool holder 40 which is guarded by theside plate 30, whereby thetool 50 is driven by thetransmission motor 20 to do chamfering operation on the stones; - The bottom of the
frame 10 is installed on amovable base 11, thesaid base 11 is installed with a pair ofsupport posts 12 at its two sides to assemble with thehandle 13. Further, thesupport posts 12 at one side of thebase 11 is horizontally pierced through with a through hole to assemble with atube connector 14 and aflexible water hose 15, wherein the saidwater hose 15 is extended to the position oftool 50 for spraying water to the operating zone oftool 50 in order to reduce the surrounding temperature and to avoid dusting, and thereby to constitute the basic functioning structure of the stone chamfering machine of the invention which is mainly characterized in the following: - The
transmission motor 20 inside theframe 10 is installed with a downward offset so as to provide an eccentric relationship between thetransmission gear 21 of thetransmission motor 20 and the convexblock 31 installed on theside plate 30 at one end of theframe 10, whereof the bottom of the convexblock 31 is provided with acut slot 32 which is extended inconcave arc 33 to the two ends to allow thetransmission gear 21 of thetransmission motor 20 to appear partially exposed, and ascrewed bolt 34 is installed at one end of the convexblock 31 on theside plate 30, whereof the saidscrewed bolt 34 is pierced through the centered throughhole 41 oftool holder 40 which enclose theside plate 30. The middle screwedsection 341 of thescrewed bolt 34 is installed with alimit ratchet wheel 35 which is engaged with and driven by thelimit ratchet gear 361 which is installed inside thecompacting plate handle 36, whereby to lock thelimit ratchet wheel 35 and thescrewed bolt 34 together, whereby to push thetool holder 40,frame 10 andside plate 30 into a complete matching relationship. Simultaneously, a pin seat is provided at a preset place on theside plate 30 to assemble with anelastic lockpin 38 which is pushed byspring 39 inside thepin seat 37 to protrude into the end face of theside plate 30, wherein through the severalpreset positioning holes 42 provided at the inside face of thetool holder 40, theelastic lockpin 38 is able to limit the related relationship between thetool holder 40,frame 10 andside plate 30 by lock inserting into any one of thepositioning holes 42 of thetool holder 40 and restrain thetool holder 40 from rotation unless theelastic lockpin 38 is retreated out of thepositioning hole 42 of thetool holder 40 by pulling the attachedpull rod 381 of theelastic lockpin 38, and through reversely rotating thelimit ratchet wheel 35 by thecompacting plate handle 36 to lessen the compression ontool holder 40 so that thescrewed bolt 34 which installed on the convexblock 31 of the side plate can be properly rotated to change position. - The
tools 50 are installed on thetool holder 40 in multi-angle and multi-axis embodiment, whereof thetool holder 40 is made to a polygon shell and is provided with ashaft hole 43 individually at its respective sides to install withbearing 44 andspindle 45, whereby it is sealed by thebearing cover 46 which is locked from outside. The inner end ofspindle 45 is installed with a drivengear 60 while the outer end ofspindle 45 is installed with atool 50 so that each side of thetool holder 40 is respectively installed withtools 50 in different specifications, whereof eachtool 50 has its own independent drivengear 60 to offer smooth change operation (such as: new tool replacement) for thetool 50 andspindle 45 if necessary. Further, oneelastic positioning pin 47 is respectively installed at a position corresponding to eachspindle 45 on thetool holder 40, whereof eachspindle 45 is provided with at least onepositioning cavity 451 to letelastic positioning pin 47 lock into it so as to prohibitspindle 45 from turning whereby to provide easy mounting/dismounting oftool 50, whereof thespring 471 which sleeves theelastic positioning pin 47 can push backelastic positioning pin 47 after disappearance of pressing force and releasespindle 45 back to its original rotating status; - As such, by employing the above disclosed structure assembling design, through the same axis installation of
tool holder 40,frame 10 andside plate 30 and the downward offset oftransmission motor 20 on theframe 10, thetransmission gear 21 of thetransmission motor 20 is able to pierce through thecut slot 32 of the center convexblock 31 on theside plate 30 offrame 10 and to reach a driving engagement relationship with the drivengear 60 ofbottom tool 50 on thetool holder 40, whereby to perform stone chamfering operation through rotating thebottom tool 50 on thetool holder 40, and in case thattool 50 of different specification is required, the operator only has to turn thecompacting plate handle 36 reversely to engage with and drive thelimit ratchet gear 35 to release the compressing status on thetool holder 40, and further to retreat theelastic lockpin 38 located at one side of theside plate 30 to release the locking relationship with thetool holder 40, then thetool holder 40 along with its installedtools 50 can be properly rotated with thescrewed bolt 34 of the convexblock 31 on the side plate as the axis, whereby to rotate thetool 50 to the bottom position oftool holder 40 and to release theelastic lockpin 38 which is pushed by itsinternal spring 39 to recover it back to the original locking position withtool holder 40. In the last step, the compacting plate handle is operated to engage and drive thelimit ratchet wheel 35 to compress thetool holder 40,frame 10 andside plate 30 to a complete match; thereby to achieve a perfect engaging relationship between the drivengear 60 of thetool 50 and thetransmission gear 21 of thetransmission motor 20 so as to recover the operating status of the stone chamfering machine. Therefore, it is particularly useful to provide atool 50 direct change function for the stone chamfering machine; i.e. as the above description has shown, the structure design of the stone chamfering machine of the invention is through the multi-axis tools at different angles on the tool holder and its offset transmission motor to obtain the transmission embodiment so that when in facing different demands of stone chamfering operation, a suitable tool can be selected by directly rotating the tool holder, thus avoiding troubles and inconveniences in repeatedly mounting/dismounting tools in the conventional structures thereby to significantly reduce the replacement man hour costs and through the design allowing tools of different specifications to be prepared at the same time, additional tool storage boxes for carry and storage are no longer required, so the tool lost problem is unlikely to happen. In general, it can really solve the existing and derived problems of the conventional one-tool stone chamfering machines to greatly promote its applicability values and usefulness to the industry. - As summarized from the above descriptions, the tool holder transmission structure of the stone chamfering machine of the invention is through the design of multi-axis tools on the tool holder and the transmission of offset motor to achieve normal stone chamfering function while the suitable tool selection and replacement can be rapidly completed by rotating the tool holder in facing different operation requirements, thus avoiding too much man hours spending on the tool replacement and the numerous troubles and inconveniences to purchase additional multiple tools for carry and storage separately. In general, it is an excellent and outstanding innovated design which has very good application and useful values to the industry. Therefore, the lawfully patent application is intended.
