Description
本發明係有關一種雙滾針倍力虎鉗，尤指能夠產生倍力夾持力的雙滾針倍力虎鉗設計。 The invention relates to a double needle roller force vise, in particular to a double needle roller force vise design capable of generating a double force clamping force.
習知的倍力虎鉗可分為機械式倍力虎鉗及油壓倍力虎鉗，機械式倍力虎鉗的倍力機制也有許多種，其中有一種雙滾針倍力虎鉗為實用效果較佳的倍力虎鉗技術，例如我國公告第507624號雙滾針推拔倍力虎鉗、M270880號高倍力定壓虎鉗、M270879號雙滾針推拔定倍力虎鉗、M270878號定力夾持之倍力虎鉗，及M435335倍力虎鉗傳動結構等。 The conventional double force vise can be divided into mechanical double force vise and hydraulic multiple force vise. The mechanical force force vise has many kinds of force mechanism. Among them, there is a double needle roller force vise for practical use. The best-purpose Bühler vise technology, such as China's Announcement No. 507624 double needle push-pull force vise, M270880 high-power constant pressure vise, M270879 double needle push-pull fixed force vise, M270878 The force clamp is used to clamp the force, and the M435335 force vise transmission structure.
上述的雙滾針倍力虎鉗主要的機制為一子螺桿通過一離合鋼珠帶動一外筒，外筒將同步帶動母螺桿轉動(母螺桿只是轉動並未前移)，進而使螺母座及活動口金快速前進。當活動口金抵靠到工件時，操作者再轉動子螺桿時，將致使離合鋼珠脫離外筒，因此子螺桿能夠透過其螺紋作用而前進，推動子螺桿前端一錐形的推拔銷，推拔銷的兩側具有斜面可以作用於雙滾針，因此能夠倍力推動母螺桿前移(此時母螺桿不轉動)，同時也能使螺母座及活動口金產生更大的推力，將工件穩固地夾持在固定口金與 活動口金之間。 The main mechanism of the above-mentioned double-needle double-force vise is that a sub-screw drives an outer cylinder through a clutch steel ball, and the outer cylinder will synchronously drive the female screw to rotate (the female screw only rotates without moving forward), thereby making the nut seat and the activity The mouth gold is moving fast. When the movable mouth gold abuts against the workpiece, when the operator rotates the sub-screw, the clutch ball will be disengaged from the outer cylinder, so that the sub-screw can advance through the thread action, pushing the tapered screw at the front end of the sub-screw, pushing and pulling The sides of the pin have a beveled surface that can act on the double needle roller, so that the mother screw can be pushed forward (in this case, the female screw does not rotate), and the nut seat and the movable port gold can be generated to generate more thrust, and the workpiece can be stably Clamped in the fixed mouth gold and Activity between the gold.
然而，上述的雙滾針倍力虎鉗仍有許多問題有待克服，其中，該子螺桿的前端面係直接接觸於推拔銷的後端面，因此子螺桿在轉動前進時，其前端面將與推拔銷的後端面產生很大的磨擦力，導致子螺桿運轉不夠滑順。再者，當該子螺桿倍力推動推拔銷時，將同時發生軸向的反作用力，導致與子螺桿相螺合的後螺桿套的階級面會與虎鉗的後端座相互磨擦，同樣導致子螺桿運轉不夠滑順，操作者必須更加費力去轉動子螺桿。 However, the above-mentioned double-needle double-force vise still has many problems to be overcome, wherein the front end surface of the sub-screw is directly in contact with the rear end surface of the push-pull pin, so that the front end face of the sub-screw will advance with the rotation forward. The rear end face of the push pin produces a large frictional force, causing the sub-screw to operate insufficiently smoothly. Furthermore, when the sub-screw force pushes the push pin, the axial reaction force will occur at the same time, so that the step surface of the rear screw sleeve screwed with the sub-screw will rub against the rear end seat of the vise. As a result, the sub-screw does not run smoothly, and the operator has to work harder to rotate the sub-screw.

Therefore, the sleeve 21 can re-transmit the connecting structure of the polygonal hole 212 and the polygonal column 151 to drive the female screw 15 to rotate, that is, the female screw 15 is used. The thread component force pushes the nut seat 14 and the movable port gold 13 forward. As shown in the seventh figure, until the clamping faces of the movable port gold 13 and the fixed port gold 12 abut against the workpiece 20, only the female screw 15 is used in this stroke. The force of the force of the thread advances. In particular, the first thrust bearing 162 and the third thrust bearing 163 can be passed through at this time to reduce the inverse of the nut sleeve 32. The force, so it achieves the effect of smooth and labor-saving rotation.
其後如第八圖所示，當活動口金13及固定口金12的夾持面都抵靠到工件20後，使用者再轉動工具10時，將使離合鋼珠343脫離離合環31的第一定位孔311，然後藉由子螺桿34與螺母套32的螺合結構，使得子螺桿34開始轉動及前進，進而透過第二止推軸承35及滑動盤36向前頂推頂桿26，頂桿26的錐部261的兩錐面262將推擠兩滾針25，使兩滾針25作用於後頂環24的斜面243，進而推動前頂環22及母螺桿15倍力前進，若此，將使母螺桿15、螺母座14及活動口金13直接向工件20產生更大的推力(夾力)，達到倍力夾持工件20的功能。特別是，上述子螺桿34開始轉動前進時，本發明將能透過第二止推軸承35及滑動盤36的設計，降低頂桿26與子螺桿34之間的磨擦力，達到轉動滑順省力的功效。 Thereafter, as shown in the eighth figure, when the clamping faces of the movable port gold 13 and the fixed port gold 12 abut against the workpiece 20, when the user rotates the tool 10 again, the clutch ball 343 is disengaged from the first position of the clutch ring 31. The hole 311 is then rotated by the screwing structure of the sub-screw 34 and the nut sleeve 32, so that the sub-screw 34 starts to rotate and advance, and then pushes the jack 26 forward through the second thrust bearing 35 and the sliding disc 36. The two tapered surfaces 262 of the tapered portion 261 will push the two needle rollers 25, so that the two needle rollers 25 act on the inclined surface 243 of the rear top ring 24, thereby pushing the front top ring 22 and the female screw 15 to advance by a force, and thus, The female screw 15, the nut seat 14 and the movable port gold 13 directly generate a larger thrust (clamping force) to the workpiece 20, thereby achieving the function of clamping the workpiece 20 with a double force. In particular, when the sub-screw 34 starts to rotate forward, the present invention can transmit the friction between the jack 26 and the sub-screw 34 through the design of the second thrust bearing 35 and the sliding disc 36, thereby achieving smooth and labor-saving rotation. efficacy.
綜上所述，本發明雙滾針倍力虎鉗，已確具實用性與進步性，其技術手段之運用亦出於新穎無疑，且功效與設計目的誠然符合，已稱合理進步至明。為此，依法提出發明專利申請，惟懇請 鈞局惠予詳審，並賜准專利為禱，至感德便。 In summary, the double needle roller double force vise of the present invention has been practical and progressive, and the application of the technical means is also novel and undoubted, and the efficacy and design purpose are in line with the fact that it has been reasonably improved. To this end, the invention patent application was filed according to law, but the bureau was requested to give a detailed examination, and the patent was granted as a prayer.
