Description

雙滑座量測台Double sliding seat measuring station

本發明與工件量測裝置有關，尤指一種以雙滑座共同固定工件的量測裝置。The present invention is related to a workpiece measuring device, in particular to a measuring device in which a workpiece is jointly fixed by a double sliding seat.

習知用於量測工件直徑、同軸度及偏心度的量測儀器如我國新型專利公告M372463號所揭露者，其具有一底座，底座上設有一滑軌以供設置兩個滑座，其中各滑座上分別伸出一頂心桿，俾藉由操作兩滑座相向靠近，並利用兩頂心桿夾掣待量測的工件，即可開始量測作業。The conventional measuring instrument used to measure the diameter, coaxiality and eccentricity of the workpiece is disclosed in my country's new patent announcement No. M372463. It has a base on which a slide rail is provided for setting two slides, each of which A mandrel rod is respectively extended from the sliding seat, so that by operating the two sliding seats close to each other, and using the two mandrel bars to clamp the workpiece to be measured, the measurement operation can be started.

上述習知裝置所適用的工件樣本必須是兩端都設有頂心孔的樣本，才能被兩滑座的頂心桿嵌入而獲得穩固夾持。然而有些工件樣本只有一端具有頂心孔，或兩端都沒有頂心孔，則上述習知裝置無法將其穩固夾持，因而無法執行測量作業。The workpiece sample to which the above-mentioned conventional device is applicable must be a sample with core holes at both ends, in order to be embedded by the core rods of the two sliding seats and be firmly clamped. However, some workpiece samples only have a center hole at one end, or do not have a center hole at both ends, the above-mentioned conventional device cannot hold it firmly, and thus cannot perform measurement operations.

又上述習知裝置係用於精密測量，例如兩滑座上頂心桿的同軸度若不足，即二者不同軸，則會導致所夾持的工件樣本歪斜；又例如底座的水平度若不足，即底座翹曲，則置於該底座上的滑座及工件樣本亦連帶形成歪斜，將不能測得正確結果，因此各構件必須達到極高的精度要求。Moreover, the above-mentioned conventional device is used for precision measurement. For example, if the coaxiality of the mandrel on the two sliding seats is insufficient, that is, the two are different in axis, the sample of the clamped workpiece will be skewed; another example is the level of the base , That is, the base is warped, the sliding seat and the workpiece sample placed on the base will also be skewed, and the correct result will not be measured. Therefore, each component must meet extremely high accuracy requirements.

再者，上述習知裝置在操作上是用手推動兩滑座到適當位置，再旋動固定螺絲將滑座固定在底座上，非常不便利且不能精準地移動滑座。Furthermore, the above-mentioned conventional device is operated by pushing the two sliding seats to the proper positions by hand, and then rotating the fixing screws to fix the sliding seats on the base, which is very inconvenient and cannot accurately move the sliding seats.

有鑑於此，如何改進上述問題即為本發明所欲解決之首要課題。In view of this, how to improve the above-mentioned problem is the primary problem to be solved by the present invention.

承上，該基座２具有一朝兩側伸出的上頂部２１，其界定為一可供兩滑座４滑移的第一滑軌２２。上述該滑座４之底端伸出一對足部４１，並跨設於該基座２之上頂部２１，再於兩足部４１上鎖固伸至該上頂部２１下方之底板４２，據此令該滑座４僅得沿該第一滑軌２２滑動，而不能以其他方向離開該基座２。On the other hand, the base 2 has an upper top 21 extending toward both sides, which is defined as a first sliding rail 22 for the two sliding seats 4 to slide. The bottom end of the sliding seat 4 protrudes from a pair of feet 41 and straddles the top 21 of the base 2. The two feet 41 are fixed to the bottom plate 42 extending below the upper top 21. As a result, the sliding seat 4 can only slide along the first sliding rail 22 and cannot leave the base 2 in other directions.

該基座２上設有兩個連接該滑座４的驅動裝置５，用以驅動該滑座４於該第一滑軌２２上滑移。於本實施例中，該基座２之頂面凹設有一容室２３，且於該基座２兩端設置一穿孔２４，各驅動裝置５包括有一螺桿５１及一手輪５２，兩螺桿５１分別自兩穿孔２４伸進該容室２３，且與該第一滑軌２２同向延伸；兩螺桿５１伸出穿孔２４的一端則與該手輪５２連接。另一方面，兩滑座４之底部分別具有一螺接部４３，並分別與一個螺桿５１對應螺接。藉由上述結構，如第３圖所示，操作人員可轉動該手輪５２以帶動對應的螺桿５１轉動，再進而透過螺旋作用帶動對應的滑座４沿該第一滑軌移動。The base 2 is provided with two driving devices 5 connected to the sliding seat 4 for driving the sliding seat 4 to slide on the first sliding rail 22. In this embodiment, the top surface of the base 2 is recessed with a chamber 23, and a perforation 24 is provided at both ends of the base 2. Each driving device 5 includes a screw 51 and a hand wheel 52. The two screws 51 are respectively The two perforations 24 extend into the chamber 23 and extend in the same direction as the first slide rail 22; the end of the two screws 51 extending out of the perforation 24 is connected to the hand wheel 52. On the other hand, the bottoms of the two sliding seats 4 are respectively provided with a screw connection part 43, which is respectively screwed with a screw 51. With the above structure, as shown in Figure 3, the operator can turn the hand wheel 52 to drive the corresponding screw 51 to rotate, and then drive the corresponding slide 4 to move along the first slide rail through the spiral action.

兩滑座４相向之一側分別設有一固定孔４４，並嵌設有一頂心桿４５，俾供卡掣於待測工件６的頂心孔６１中，並操作兩滑座４相向滑移以達迫緊工件６之固定效果。上述兩滑座４之固定孔４４係位於同一軸向上，使所嵌設的兩頂心桿４５亦位於同一軸向上。該固定孔４４的成形方法係如第４圖所示地先將兩滑座４靠攏，再於同一工序中一併切削兩滑座４，據此同時製成兩滑座４的固定孔４４，以確保兩固定孔４４的同軸度。The opposite sides of the two sliding seats 4 are respectively provided with a fixing hole 44, and a mandrel 45 is embedded in it, so as to be clamped in the mandrel hole 61 of the workpiece 6 to be tested, and the two sliding seats 4 are operated to slide in opposite directions. Achieve the fixed effect of pressing the work piece 6. The fixing holes 44 of the two sliding seats 4 are located in the same axial direction, so that the two embedded mandrels 45 are also located in the same axial direction. The method of forming the fixing hole 44 is as shown in Figure 4 by first bringing the two sliding seats 4 close together, and then cutting the two sliding seats 4 together in the same process, and thereby forming the fixing holes 44 of the two sliding seats 4 at the same time. To ensure the coaxiality of the two fixing holes 44.

此外，兩滑座４之頂面分別設有一夾角為90度的Ｖ形溝槽４６，兩Ｖ形溝槽４６係位於同一軸向上，其成形方法亦同前述的固定孔４４而可確保其同軸度。In addition, the top surfaces of the two sliding seats 4 are respectively provided with a V-shaped groove 46 with an included angle of 90 degrees.
