Abstract
The utility model relates to a boring tool holder with a measuring device, which is composed of a holder body taper shank, a boring tool holder of the tool holder slide block and an electronic digital display device which is composed of a displacement sensing marking rule and an electronic digital display which is sheathed on the displacement sensing marking rule. The displacement sensing marking rule and the digital display are respectively fixedly connected with the holder body taper shank and the tool holder slide block, the tool holder corresponding to the holder body taper shank slides for a displacement which is transferred to the digital display to display by the displacement sensing marking rule. The utility model has simple structure, precise measuring ranges, obvious and intuitionistic display and convenient use and is especially suitable for the processing use of various high precision borings.
Description
The utility model relates to a kind of machining machinery.What be particularly related to is a kind of boring tool holder that has measurement mechanism.
Existing common boring tool holder, the depth of cut of its boring cutter are to be shown by the dial that is arranged on the feed screw mandrel end face.Its precision is subjected to engaged transmission gap between pitch, feed screw mandrel and the knife rest slide block of feed screw mandrel and all multifactor impacts such as manufacturing assembly precision between driving member, the reading on the dial and the actual displacement of knife rest slide block are not inconsistent, cause machining accuracy not high, even workpiece is scrapped.For overcoming this deficiency, Chinese patent CN2048796U discloses a kind of " Boring head with meter ", by the measurement mechanism of being made up of guide shaft, fixture block, amesdial is installed on traditional boring head taper shank, utilizing amesdial gauge head and boring head knife rest slide block outer end to become vertical contacts or contacts with cutter head, determine the displacement of knife rest slide block by the amesdial reading, adjust the dimensional accuracy of bore hole.This is that the weak point of the boring tool holder of measuring instrument is to cause the amesdial pointer to beat easily under the effect of the rotary centrifugal force when work and make pointer produce the error of indication under the effect of cutting impulsive force easily with the amesdial; Simultaneously, the use stroke of amesdial is very little, and the scope of application is restricted, and reading is obviously not directly perceived yet.
The purpose of this utility model is the above-mentioned deficiency that overcomes prior art; Provide that a kind of precision height, range are big, easy operating control and the reading explicit boring tool holder of electron number intuitively.
The explicit boring tool holder of electron number of realizing the purpose of this utility model comprises support body taper shank and knife rest slide block, the support body taper shank has dovetail groove, the knife rest slide block is located in the dovetail groove of support body taper shank and can slides along dovetail groove, of the present utility modelly be characterised in that described boring tool holder also is provided with an electronic digital display apparatus, described electronic digital display apparatus indicates chi by displacement sensing and is sleeved on the device for digit-displaying that this displacement sensing indicates on chi and constitutes, described device for digit-displaying and displacement sensing indicate chi respectively with the support body taper shank and the knife rest slide block Joint of boring tool holder.Both: device for digit-displaying can be fixed on the support body taper shank, displacement sensing indicates chi and be fixed on the knife rest slide block, when the knife rest slide block being moved when adjusting the boring cutter depth of cut, the displacement sensing that is fixed in the electronic digital display device on the knife rest slide block indicates the also same thereupon moved further of chi, and its distance that moves then is sleeved on the device for digit-displaying that indicates on the chi and receives and show on its digital display screen.Also can be conversely the displacement sensing of electronic digital display apparatus be indicated that chi is fixed on the support body taper shank, device for digit-displaying is fixed on the knife rest slide block, with moved further its displacement is shown along with the mobile drive device for digit-displaying of knife rest slide block indicates on the chi at displacement sensing.
The utility model compared with prior art, have structure more simple, use, control is more convenient and range accurately, show advantage obviously directly perceived, accurate and reliable.Press the zero setting button of display, can carry out the absolute of mobile numerical value or show that relatively realization carries out absolute to the processing aperture or increment size shows, can be convenient to process operation greatly.
Below in conjunction with drawings and Examples the utility model is described further.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the vertical view of Fig. 1
Fig. 3 is the left view of Fig. 1
Fig. 4 is the right view of Fig. 1
Shown in Fig. 1～4, what present embodiment provided is that a kind of displacement sensing sign chi is fixed in the version on the knife rest slide block.Its formation comprises boring tool holder support body taper shank 1, be equipped with knife rest slide block 2 in the dovetail groove of support body taper shank 1, be arranged on the feed screw mandrel 3 in the internal thread hole of knife rest slide block 2, above-mentioned part all can be continued to use existing common boring tool holder, electronic digital display device 8 is fixed on the support body taper shank 1, and the displacement sensing sign chi 7 that interts in electronic digital display device 8 can be fixed on the knife rest slide block 2 by support 6 and coupling block 9.Rotate feed screw mandrel 3 during use, 2 of knife rest slide blocks that are socketed on this screw mandrel slide in the dovetail groove of support body taper shank thereupon, the displacement sensing that is fixed in the electronic digital display apparatus on the knife rest slide block 2 indicates chi 7 also along with the mobile and same moved further of knife rest slide block, and its distance that moves is then received by the electronic digital display device and illustrates on its display screen 10.
Claims (3)
1, the explicit boring tool holder of electron number, comprise support body taper shank and knife rest slide block, the support body taper shank has dovetail groove, the knife rest slide block is located in the dovetail groove of support body taper shank and can slides along dovetail groove, it is characterized in that described boring tool holder also is provided with an electronic digital display apparatus, described electronic digital display apparatus indicates chi by displacement sensing and is sleeved on the device for digit-displaying that displacement sensing indicates on the chi and constitutes, described device for digit-displaying and displacement sensing indicate chi respectively with the support body taper shank and the knife rest slide block Joint of boring tool holder.
2, boring tool holder as claimed in claim 1 is characterized in that the displacement sensing sign chi and the knife rest slide block of described electronic digital display apparatus is affixed, and device for digit-displaying and support body taper shank are affixed.
