Description

Technical Field

[0001] This utility model relates to the field of drilling tooling technology, and more specifically, to a pressure bar drilling tooling. Background Technology

[0002] Various types of fixtures are widely used in the processes of various industries of mechanical manufacturing to fix the workpiece in the correct position for machining. Therefore, a large number of fixtures are required in each process of machining. The use of fixtures can make full use of the potential of existing equipment, enable workers to master the machining of complex or precision parts, and greatly improve production efficiency and product quality.

[0003] Among fixtures, drilling fixtures are the most widely used. When using a drilling fixture, the workpiece must first be positioned in the fixture, and then drilling equipment such as a drilling machine is used to process the required holes on the workpiece. However, some existing drilling fixtures generally have the problems of overly complicated workpiece positioning, cumbersome installation and disassembly steps, and poor positioning effect. Therefore, we provide a pressure bar drilling fixture. Utility Model Content

[0004] The purpose of this utility model is to provide a pressure bar drilling fixture to solve the problems mentioned in the background art above:

[0005] Currently available drilling fixtures generally suffer from problems such as overly complex workpiece positioning, cumbersome installation and disassembly procedures, and poor positioning performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A drilling fixture includes a lower positioning seat and an upper positioning seat. The lower and upper positioning seats are used to position the workpiece for subsequent drilling. The upper surface of the lower positioning seat has a first transverse positioning groove and a first longitudinal positioning groove, which communicate with the first transverse positioning groove. The interior of the lower positioning seat has a first through hole, which communicates with the first longitudinal positioning groove. The lower surface of the upper positioning seat has a second transverse positioning groove and a second longitudinal positioning groove, which communicate with the second transverse positioning groove. The interior of the upper positioning seat has a second through hole, which communicates with the second longitudinal positioning groove. The second through hole and the first through hole are used for the drill bit to pass through.

[0008] Preferably, there are two first longitudinal positioning slots, which are symmetrically distributed and arranged in a U-shape with the first transverse positioning slot. The workpiece can be placed into the first longitudinal positioning slot and the first transverse positioning slot on the lower positioning seat.

[0009] Preferably, the first transverse positioning groove and the second transverse positioning groove have the same size, and the first longitudinal positioning groove and the second longitudinal positioning groove have the same size. After the lower positioning seat and the upper positioning seat are assembled together, the workpiece can be positioned through the first transverse positioning groove, the second transverse positioning groove, the first longitudinal positioning groove and the second longitudinal positioning groove.

[0010] Preferably, the lower positioning seat has four first mounting holes inside. The four first mounting holes are symmetrically distributed, and the four first mounting holes are arranged in pairs. They are symmetrically distributed at both ends of the lower positioning seat near the inner side. The lower positioning seat can be fixed to the worktable of the drilling machine by means of bolts through the first mounting holes.

[0011] Preferably, the upper positioning seat has two second mounting holes inside, which are symmetrically distributed. The second transverse positioning groove and the second longitudinal positioning groove are located on one side of the upper positioning seat, while the two second mounting holes are located on the other side of the upper positioning seat.

[0012] Preferably, the second mounting hole is an elongated structure. The upper positioning seat can be installed on the lifting slide of the drilling machine through the second mounting hole and the bolt. The lifting slide of the drilling machine can drive the drill bit and the upper positioning seat to move up and down. The upper positioning seat will contact the workpiece first and cooperate with the lower positioning seat to position the workpiece. The elongated structure of the second mounting hole facilitates the adjustment of the position of the upper positioning seat, so that the first through hole and the second through hole can be ensured to be on the same straight line.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The lower positioning seat is fixed to the worktable of the drilling machine, and then the upper positioning seat is fixed to the lifting slide of the drilling machine. Since the second mounting hole is a long strip structure, the position of the upper positioning seat can be adjusted so that the second through hole and the first through hole are on the same straight line. Then, the workpiece to be drilled is placed in the first transverse positioning groove and the first longitudinal positioning groove. The lifting slide of the drilling machine is controlled to move downward so that the upper positioning seat and the lower positioning seat fit together, thereby positioning the workpiece. As the lifting slide of the drilling machine continues to move downward, the drill bit will first pass through the second through hole and then drill the workpiece. Finally, the drill bit passes through the first through hole to complete the drilling of the workpiece. The overall structure of the fixture is simple, easy to install, has a good positioning effect, and is highly practical. Attached Figure Description

[0020] Please see Figures 1 to 3 A drilling fixture for pressure bars includes a lower positioning seat 1 and an upper positioning seat 2. The lower positioning seat 1 and the upper positioning seat 2 are used to position the workpiece to facilitate subsequent drilling. The upper surface of the lower positioning seat 1 has a first transverse positioning groove 3 and a first longitudinal positioning groove 4, which are connected to the first transverse positioning groove 3. The interior of the lower positioning seat 1 has a first through hole 5, which is connected to the first longitudinal positioning groove 4. The lower surface of the upper positioning seat 2 has a second transverse positioning groove 6 and a second longitudinal positioning groove 7, which are connected to the second transverse positioning groove 6. The interior of the upper positioning seat 2 has a second through hole 8, which is connected to the second longitudinal positioning groove 7. The second through hole 8 and the first through hole 5 are used for the drill bit to pass through. The drill bit will first pass through the second through hole 8, then drill the workpiece, and finally pass through the first through hole 5.

[0021] Furthermore, there are two first longitudinal positioning grooves 4, which are symmetrically distributed. The two first longitudinal positioning grooves 4 and the first transverse positioning groove 3 are arranged in a U-shape. Before drilling the workpiece, the workpiece can be placed in the first longitudinal positioning groove 4 and the first transverse positioning groove 3 on the lower positioning seat 1.

[0022] Furthermore, the first transverse positioning groove 3 and the second transverse positioning groove 6 have the same dimensions, and the first longitudinal positioning groove 4 and the second longitudinal positioning groove 7 have the same dimensions. After the lower positioning seat 1 and the upper positioning seat 2 are assembled together, the workpiece can be positioned through the first transverse positioning groove 3, the second transverse positioning groove 6, the first longitudinal positioning groove 4 and the second longitudinal positioning groove 7. The first transverse positioning groove 3, the second transverse positioning groove 6, the first longitudinal positioning groove 4 and the second longitudinal positioning groove 7 are adapted to the workpiece.

[0023] Furthermore, the lower positioning seat 1 has four first mounting holes 9 inside. The four first mounting holes 9 are symmetrically distributed, and the four first mounting holes 9 are arranged in pairs. They are symmetrically distributed at both ends of the lower positioning seat 1 near the inner side. The lower positioning seat 1 can be fixed to the worktable of the drilling machine by means of the first mounting holes 9 and bolts.

[0024] Furthermore, the upper positioning seat 2 has two second mounting holes 10 inside. The two second mounting holes 10 are symmetrically distributed. The second transverse positioning groove 6 and the second longitudinal positioning groove 7 are located on one side of the upper positioning seat 2, while the two second mounting holes 10 are located on the other side of the upper positioning seat 2.

[0025] Furthermore, the second mounting hole 10 has an elongated shape. Through the second mounting hole 10 and the bolts, the upper positioning seat 2 can be installed on the lifting slide of the drilling machine. The lifting slide of the drilling machine can drive the drill bit and the upper positioning seat 2 to move up and down. The upper positioning seat 2 will first contact the workpiece and cooperate with the lower positioning seat 1 to position the workpiece. The elongated shape of the second mounting hole 10 facilitates the adjustment of the position of the upper positioning seat 2, so that the first through hole 5 and the second through hole 8 can be ensured to be on the same straight line and there will be no misalignment.

[0026] The steps of using this utility model are as follows: When using this pressure bar drilling fixture, the lower positioning seat 1 is fixed to the worktable of the drilling machine through the first mounting hole 9 and bolts. Then, the upper positioning seat 2 is fixed to the lifting slide of the drilling machine through the second mounting hole 10 and bolts. Since the second mounting hole 10 is a long strip structure, the position of the upper positioning seat 2 can be adjusted so that the second through hole 8 and the first through hole 5 are on the same straight line. Then, the workpiece to be drilled is placed in the first transverse positioning groove 3 and the first longitudinal positioning groove 4. The lifting slide of the drilling machine is controlled to move downward so that the upper positioning seat 2 and the lower positioning seat 1 are in contact. At this time, under the combined action of the first transverse positioning groove 3, the second transverse positioning groove 6, the first longitudinal positioning groove 4 and the second longitudinal positioning groove 7, the workpiece can be positioned. As the lifting slide of the drilling machine continues to move downward, the drill bit will first pass through the second through hole 8 and then drill the workpiece. Finally, the drill bit passes through the first through hole 5 to complete the drilling of the workpiece. The fixture has a simple overall structure, is easy to install, has a good positioning effect, and is highly practical.
