The patent is a clamping frock of adjustable height that well box used when boring the pinhole above the big terminal surface in the vertical machining center.
As shown in fig. 1,2, 3 and 4:
Wherein the middle box body 1 is placed on a machine tool workbench 2 for processing.
The T-shaped bolts 5 penetrate through the T-shaped grooves 21 on the machine tool workbench 2, the T-shaped bolts 5 penetrate through the through holes 31 formed in the tool supports 3, and one tool support 3 is provided with two T-shaped bolts 5, so that the tool supports 3 are positioned on the machine tool workbench 2. Each T-shaped bolt 5 is screwed into two mutually propped round nuts 4, and the round nuts 4 below are tightly pressed on the tool support 3, so that the tool support 3 is fixedly arranged on the machine tool workbench 2, and the two round nuts 4 play a role in preventing falling.
A total of 4 support components formed by tool supports 3, round nuts 4, T-shaped bolts 5 and semicircular head tool bolts 6 are arranged, 1 support component is arranged in the upper direction, the lower direction, the left direction and the right direction respectively, and the circumference of the support components is uniformly arranged on a machine tool workbench 2.
Screw holes 32 with certain specification depth are processed in advance on the upright post end faces of the tool support 3, and the semicircular head tool bolts 6 are screwed into the screw holes 32 and are connected with the upright post end faces of the tool support 3 in a threaded fixing mode.
The head of the half-head tooling bolt 6 is in a half-head form and is propped against the large end face below the middle box body 1, the half-head tooling bolt is contacted with the large end face below the middle box body 1 in a point contact mode, the end face of the middle box body 1 in a workpiece needs to be corrected before machining, if the perpendicularity of the large end face to be machined of the middle box body 1 does not meet the requirement, the depth of a torsion threaded hole 32 of the tooling bolt 6 is adjusted through opening spanner plate movement to control the height of the half-head tooling bolt 6 until the gauge of the workpiece meets the machining requirement, and the posture of the adjusted middle box body 1 supports the middle box body 1 and then is machined by a vertical lathe.
Thus, the height of the half-head tooling bolt 6 is controlled by adjusting the screwing depth of the half-head tooling bolt 6, so that the optimal contact point between the half-head tooling bolt 6 and the large end face of the middle workpiece box body 1 can be controlled, the end face of the middle workpiece box body 1 needs to be corrected before machining, and if the perpendicularity of the large end face to be machined of the middle box body 1 does not meet the requirement, the half-head tooling bolt 6 contacts with the lower end face (gear ring joint face) of the middle box body 1 in the upper, lower, left and right directions of the middle box body 1, and the half-head tooling bolt 6 can be properly pulled to be adjusted until the correction table of the workpiece meets the machining requirement.
In this form, the tool support 3 may be fixed after being moved over the machine table 2 so that the tool bolts 6 support the intermediate housing 1 in the most appropriate stable position.
The tool cushion block 13, the jack assembly 14, the tool pressing plate 15, the round nuts 16, the T-shaped bolts 17 and the semicircular-head tool bolts 141 form a pressing assembly, 4 pressing assemblies are needed, the pressing assemblies are staggered with the supporting assemblies formed by the tool support 3, the round nuts 4, the T-shaped bolts 5 and the semicircular-head tool bolts 6, and the pressing assemblies are staggered and arranged in a staggered manner and uniformly distributed on the machine tool workbench 2 in circumference.
The tool cushion block 13 is placed on the machine tool workbench 1, the jack assembly 14 is placed on the tool cushion block 13, a screw hole is formed in the top of the jack assembly 14, the head of the semicircular head tool bolt 141 is in a semicircular head mode, the semicircular head tool bolt 141 is screwed into the screw hole, one side of the tool pressing plate 15 is placed on the semicircular head tool bolt 141, the other side of the tool pressing plate 15 is placed on the back face (the back face of the gear ring joint face) of the large end face below the box body 1 in the workpiece, a waist-shaped hole 151 with a certain size range is formed in the center of the tool pressing plate 15, the head of the T-shaped bolt 17 is placed in a T-shaped groove 21' on the machine tool workbench 2, the other side of the T-shaped bolt 17 penetrates through the waist-shaped hole 151 on the tool pressing plate 15, two mutually propped round nuts 16 are screwed onto the T-shaped bolt 17, and after the round nuts 16 are tightly contacted with the tool pressing plate 15, the other side of the tool pressing plate 15 is tightly pressed and fixed.
The existing tooling used for the fine boring procedure of the middle box body on the vertical machining center supports the large end face below the middle box body by three to four equal-height blocks with fixed heights. Because casting and processing errors exist in the parts, after one equal-height block contacts the end face, gaps possibly exist between the upper end faces of the other equal-height blocks and the large end face below the middle box body, and at the moment, proper height is adjusted by raising the heights of the equal-height blocks on one side, so that the efficiency is too low. The height of the bolt is controlled by manually plate-moving the semicircular head tooling bolt positioned on the tooling support through the open spanner, so that the distance from the large end face to be machined of the middle box body to the end face of the main shaft of the machine tool can be adjusted, and the correction requirement before machining of a workpiece is met. Therefore, the efficiency of workpiece correction by clamping the parts is effectively improved, and the cost of additionally manufacturing tools due to the fact that the height of the equal-height iron is not matched is reduced.
The tool provided by the utility model has the advantages that:
The structure is simple, and the processing and the manufacturing are easy;
the universality is stronger, and the tooling cost is saved;
the operation can be carried out by a single person, so that the labor cost is reduced;
the supporting height of the middle box body is adjusted at any time by correcting the workpiece, the requirement is not met, only the half-round head tooling bolts on the tooling upright posts are required to be adjusted, and the efficiency is higher.
