The specific meaning of the above terms in the embodiments of the present invention can be understood by those skilled in the art according to specific situations.
With reference to fig. 1 and 3, an embodiment of the present invention provides a chuck centering tool clamp, including: a centering device 1 and a chuck tool 4; the chuck tool 4 is used for clamping and fixing a workpiece 5 to be processed; the chuck tool 4 is arranged above the centering device 1, and when the drilling machine 3 drills the workpiece 5 to be machined, the centering device 1 can balance the stress of the chuck tool 4, so that the machining center deviation of the end face of the workpiece 5 to be machined is prevented.
The embodiment of the utility model provides a through having adopted centring means 1 and chuck frock 4, set up centring means 1 in chuck frock 4 below, when drilling machine 3 fixed waiting to process work piece 5 on chuck frock 4 and process, chuck frock 4 can the atress uneven, lead to waiting to process work piece 5 off-centre, at this moment, centring means 1 balances the atress of chuck frock 4, the easy off-centre problem of waiting to process work piece 5 in the course of working has effectively been solved, and then realized waiting to process work piece 5 at the accurate location of work piece machining center in the course of working such as drilling or awl silk.
During the actual operation process, place centring means 1 on the operation panel to fixing centring means 1 both sides, specifically pressing from both sides at centring means 1 through the iron plate and pressing from both sides tightly, fixing the iron plate on the operation panel through the bolt, guarantee that centring means 1 can not remove in the course of working.
The method comprises the steps of fixedly installing a chuck tool 4 above a centering device 1, clamping a workpiece 5 to be processed on the chuck tool 4, aligning the drilling center of the workpiece 5 to be processed with a screw tap 2 or a drill cutter installed on a drilling machine 3, and then performing drilling or taper thread operation.
In one possible implementation, as shown in fig. 1, the chuck tooling 4 includes: a pallet 41, a chuck 42, and jaws 43; the supporting plate 41 is arranged above the centering device 1; the chuck 42 is provided on the pallet 41, the jaws 43 are provided on the chuck 42, and the jaws 43 clamp and fix the workpiece 5 to be machined.
Specifically, will treat that processing work piece 5 presss from both sides tight fixedly through jack catch 43, and jack catch 43 adjusts through chuck 42, realizes treating the tight and initial positioning of clamp of processing work piece 5, is fixed in on layer board 41 with chuck 42 to guarantee that chuck 4 can be steady place on the operation panel or be convenient for fix chuck frock 4 and positioner 1.
In one possible implementation, as shown in fig. 1, the centering device 1 comprises: a base plate 11, an elastic member 12, and a bolt 13; the supporting plate 41 is fixedly arranged above the bottom plate 11 through a bolt 13, and a preset space is arranged between the supporting plate 41 and the bottom plate 11 at an interval; the elastic member 12 is disposed in a preset space between the bottom plate 11 and the supporting plate 41, and two ends of the elastic member 12 are respectively in contact with the bottom plate 11 and the supporting plate 41; when the stress on the chuck tooling 4 is unbalanced, the elastic piece 12 can be compressed and deformed along the direction from the supporting plate 41 to the bottom plate 11 and can be automatically reset.
Specifically, when the stress on the supporting plate 41 is unbalanced, the elastic member 12 located below the supporting plate 41 is compressed and generates a reaction force, and the reaction force provides a supporting force for the supporting plate 41 to ensure that the stress on the supporting plate 41 is balanced.
In the scheme, the bottom plate 11 and the supporting plate 41 are respectively provided with screw holes, the bottom plate 11 and the supporting plate 41 are connected and fixed through the bolts 13, the bolts 13 between the bottom plate 11 and the supporting plate 41 are reserved with a certain height, and the elastic part 12 is arranged in the reserved space. During operation, the bolt 13 penetrates through the screw hole on the supporting plate 41, then the elastic element 12 is placed in the reserved space, the elastic element 12 is ensured to be in contact with the bottom surface of the supporting plate 41 and the top surface of the bottom plate 11, and then the bolt 13 is fixed on the screw hole of the bottom plate 11. It should be noted that the number and location of the resilient members 12 must be such as to balance the unbalanced forces experienced in the center of the chuck tooling 4. With the arrangement, the supporting plate 41 can be guaranteed to be under the condition of unbalanced force, the force formed by compressing the elastic piece 12 balances the unbalanced force applied to the supporting plate 41, so that the supporting plate 41 is kept horizontal, the workpiece 5 to be machined fixed on the chuck 42 is further guaranteed not to deviate in the drilling center in the machining process, and the finished product rate of workpiece machining is improved.
In a possible implementation, the elastic element 12 is one and is arranged in the central position of the supporting plate 41, which is not shown in the figures.
Because the drilling center of the workpiece 5 to be processed is located at the center of the supporting plate 41, in the scheme, the elastic part 12 is arranged at the center of the supporting plate 41, when the center of the supporting plate 41 is stressed to have deviation, the stability of the drilling center during drilling can be ensured through the adjustment of the elastic part 12, and the installation is facilitated because the number of the elastic parts 12 is small.
In one possible implementation, as shown in fig. 2, the elastic member 12 is a compression spring, and the compression spring is sleeved on the bolt 13 between the bottom plate 11 and the supporting plate 41.
The elastic member 12 may be a compression spring, which generates a force opposite to the compression force when receiving the compression force, and thus may be used as a member for generating a balance force. On locating the bolt between bottom plate 11 and layer board 41 with compression spring cover, lead compression spring through bolt 13, make compression spring only can follow bolt 13's axial motion to can guarantee compression spring's stability, and then guarantee the stability of the reaction force that compression spring provided.
In one possible implementation, as shown in fig. 2, four bolts 13 are provided and are respectively provided at two symmetrical corners of the supporting plate 41.
In this embodiment, specifically, the supporting plate 41 and the bottom plate 11 have the same shape, and are both circular or square, and four bolts 13 are provided. When the supporting plate 41 and the bottom plate 11 are both square, the bolts 13 are arranged at four corners of the square; when the support plate 41 and the bottom plate 11 are both circular, the bolts 13 are arranged at two ends of two perpendicular diameters of the circular shape, and it is required to ensure that a connecting line between every two opposite bolts 13 is perpendicular. Therefore, according to the stress characteristic, the chuck tool 4 can be ensured to have another opposite force to balance the chuck tool when the chuck tool is subjected to overlarge force in any direction.
The embodiments in the present specification are described in a progressive manner, and the same or similar parts among the embodiments may be referred to each other, and each embodiment focuses on the differences from the other embodiments.
The above embodiments are only used to illustrate the technical solutions of the present application, and not to limit the present application; although the present application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications or substitutions do not depart from the spirit and scope of the present disclosure.
