[0031] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figure 1 , Figure 2 and Figure 3, is a schematic diagram of the structure of the foot roller frame 1 which is the processing object of the present invention. The foot roller frame 1 is welded by a panel 1-5 and a positioning block 1-1, a positioning block 2-2, a positioning block 3-1-3, and a positioning block 4-1-4. Four hole systems, namely, hole system 1-2, hole system 2-3, hole system 3-4, and hole system 4-5, need to be processed on the four positioning blocks; hole system 1-2 is composed of small hole 1-1 and blind hole 1-3, and a part of the small hole 1-1 is half hole 1-2, and the diameter of the small hole 1-1 is smaller than the diameter of the blind hole 1-3; hole system 2-3 is composed of small hole 2-1 and blind hole 2-3, and a part of the small hole 2-1 is half hole 2-2, and the diameter of the small hole 1-1 is smaller than the diameter of the blind hole 1-3. The diameter of hole 3-1 is smaller than the diameter of blind hole 3-3; hole system 3-4 is composed of small hole 3-1 and blind hole 3-3, part of which is half hole 3-2, and the diameter of small hole 3-1 is smaller than the diameter of blind hole 3-3; hole system 4-5 is composed of small hole 4-1 and blind hole 4-3, part of which is half hole 4-2, and the diameter of small hole 4-1 is smaller than the diameter of blind hole 4-3. Four hole systems are coplanar, and on plane 6, the angle between plane 6 and panel 1-5 is A (see Figure 1 There are two middle holes 7 and four outer holes 8 on the panel 1-5. The tolerance of the two middle holes 7 is H7 during processing, which is used as the positioning reference during the subsequent boring machine processing. The four outer holes 8 are used for fixing during the boring machine processing.

[0033] The present invention discloses a processing tool for the inclined hole system of a foot roller frame, comprising a boring die 9 and a reamer 14 with a front guide rod, which are matched and cooperated to complete the processing of the inclined hole system of the foot roller frame 1.

[0034] Reference Figure 4 , Figure 5 , Figure 6 and Figure 7 The boring die 9 includes a face plate 9-1 and a bottom plate 9-2, and an angle B (see Figure 5 ) should be equal to the angle A on the foot roller frame 1 (see Figure 1 );

[0035] Four inclined hole processing plate groups are processed on the panel 9-1, and the four inclined hole processing plate groups correspond to the hole series 1 2, the hole series 2 3, the hole series 3 4, and the hole series 4 5; the four inclined hole processing plate groups are parallel to the four sides of the panel 9-1 respectively;

[0036] Each inclined hole processing plate group includes an alignment plate welded at the edge of the panel 9-1, an alignment hole 10-1 is processed on the alignment plate, and a support plate and a drilling template are also welded side by side on the panel 9-1;

[0037] The support plate is provided with a support hole 10-2, the drilling template is provided with a drilling template hole 10-4, and the alignment hole 10-1, the support hole 10-2 and the drilling template hole 10-4 are located on the same axis;

[0038] A supporting copper sleeve 10-3 is also horizontally arranged in the supporting hole 10-2, and a drilling sleeve 10-5 is also horizontally arranged in the drilling template hole 10-4. The supporting copper sleeve 10-3 and the drilling sleeve 10-5 are located on the same axis;

[0039] The center of the alignment hole 10-1 is concentric with the hole system 2, the support hole 10-2 is set at 5 to 10 mm from the side of the half hole 2-2 and is concentric with the hole system 2, the support hole 10-2 is provided with a support copper sleeve 10-3 for supporting the guide rod reamer when in use, the drilling jig hole 10-4 is set 5 to 10 mm in front of the blind hole 2-3 and is concentric with the hole system 2, and a quenched drill sleeve 10-5 is set in the drilling jig hole 10-4 for guiding the drill bit and reamer when drilling and reaming the blind hole 2-3;

[0040] A positioning hole 11 and a long hole 12 are processed at the corresponding positions of the four hole systems on the panel 9-1, and the positioning hole 11 and the long hole 12 are located on the same axis; the diameter of the positioning hole 11 is the same as the diameter of the middle hole 7, and the tolerance is H7. The width of the long hole 12 is the same as the diameter of the middle hole 7, and the tolerance is also H7, which is used for positioning during use; according to the relative positions of the four outer holes 8 and the four hole systems on the foot roller frame 1, four engaging screw holes 13 are processed at the corresponding positions of the four hole systems on the panel 9-1, and the specifications of the four engaging screw holes 13 are matched with the diameters of the four outer holes 8, and are used for engaging with bolts during use; the four engaging screw holes 13, the positioning hole 11 and the long hole 12 are distributed in a rectangular shape on the panel 9-1.

[0041] The reamer 14 with a front guide rod includes a tapered shank reamer body, and a front guide rod 15 is provided at the front propulsion end of the tapered shank reamer body. The front guide rod 15 can be clearance-matched with the supporting copper sleeve 10-3, and the small clearance of the diameter is H7 / g6, which can ensure both normal rotation and processing accuracy. The length of the front guide rod 15 should meet the requirement that when the cutting part of the reamer starts to process the small hole 2-1, the front guide rod 15 has entered the hole of the supporting copper sleeve to start guiding, so that the centering can be ensured when reaming the small hole 2-1, especially when reaming a half hole 2-2, the phenomenon of tool letting go is avoided because the reamer only cuts semicircularly, which fails to meet the use requirements of the product. The guiding effect of the front guide rod 15 and the supporting copper sleeve hole on the reamer can greatly eliminate the phenomenon of tool letting go when reaming the half hole 2-2.

[0042] The present invention provides a processing method for the inclined hole system of a foot roller frame, which is implemented by using the above-mentioned tooling according to the following steps:

[0043] Step 1. Reference Fig. 9 , Fig.10 and Fig.11, hoist the foot roller frame 1 with two middle holes 7 and four outer holes 8 processed in advance onto the boring die 9, align the two middle holes 7 on the foot roller frame 1 with a positioning hole 11 and a long hole 12 on the boring die 9 respectively and insert two pins 16, the tolerance of the pins 16 and the holes is H7 / g6; use the four outer holes 8 on the foot roller frame 1 and the four screw holes 13 on the boring die 9 to bolt the foot roller frame 1 and the boring die 9 together. Due to the angle B (see Figure 5 ) and angle A (see Figure 1 ) angle is the same, so the plane 6 where the hole system to be processed is located and the lower bottom surface of the boring die 9 (i.e. Fig.10 The bottom of the boring die 9 is parallel to the bottom surface of the boring die 9, that is, the axis of the hole system to be processed is parallel to the bottom surface of the boring die 9 (that is, Fig.10 and each hole system is concentric with the corresponding alignment holes, support holes, and jig holes.

[0044] Step 2, the boring die 9 and the foot roller frame 1 are aligned according to the alignment reference and clamped on the working table of the boring machine;

[0045] Step 3: Rotate the workbench so that the hole is aligned with the 2-axis (i.e. Fig.10 The right end face is facing the boring machine spindle, and the alignment is made according to the circle of the alignment hole 10-1, so that the center of the boring machine spindle is concentric with the alignment hole 10-1. Since the axis of the hole system 2 is concentric with the alignment hole 10-1, the boring machine spindle is concentric with the axis of the hole system 2 to be processed.

[0046] Step 4: Install the drill bit on the boring machine spindle through the drill rod, and first drill the small hole 2-1 and the half hole 2-2 as pre-holes before reaming.

[0047] Step 5: Reference Fig.12 The boring machine spindle is equipped with a reamer 14 with a front guide rod through a drill rod 17 to ream a small hole 2-1 and a half hole 2-2. During reaming, the reamer is guided by the front guide rod 15 and the support hole 10-2, which can greatly eliminate the phenomenon of the tool letting go when reaming a half hole 2-2.

[0048] Step 6: Reference Fig.13 The spindle of the boring machine is equipped with a slender drill rod 18, which passes through the alignment hole 10-1, the processed small hole 2-1 and the half hole 2-2, and the support hole 10-2 in sequence, and then the drill bit and the reamer are installed in sequence. The drill bit and the reamer are guided by the drilling jig hole 10-4, and the blind hole 2-3 is drilled and reamed to meet the requirements, and the hole system 2 is processed.

[0049] According to this method, the processing of the remaining hole systems is completed in sequence by rotating the worktable.
