DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1 As shown, a preferred embodiment of the utility model proposes an XYZ support and adjustment device for a thread rolling machine, which is used to be installed in the thread rolling machine, and has spindle components on both sides. When the product to be processed is placed on the support and adjustment device, the two spindle components will approach the product to be processed and perform thread rolling on it.

[0029] refer to Figure 1-Figure 3 The support and adjustment device mainly includes a base plate 1, a lifting base 14, a support plate 2, a wedge block 15, a driving mechanism and other components, wherein a slide rail 4 is provided at the bottom of the base plate 1, and the slide rail 4 slides along the X-axis direction of the thread rolling machine, and the sliding direction is consistent with the axial direction of the spindle component. There are grooves 101 on the upper part and the bottom surface of the base plate 1, and the slide rail 4 is installed in the groove 101 at the bottom of the base plate 1, and baffles 8 are provided at both ends of the upper part of the base plate 1, and limit plates 9 are provided on both sides of the upper part of the base plate 1. The baffles 8 and the limit plates 9 are fixed to the base plate 1 by bolts. The middle area at the bottom of the baffle 8 bulges downward, and the bulge is embedded in the groove 101 on the upper part of the base plate 1, so as to limit the baffle 8 and prevent the baffle 8 from moving left and right.

[0030] The two baffles 8 and the two limiting plates 9 cooperate to enclose a rectangular cavity in the middle, and the lifting base 14 and the wedge block 15 are both located in the cavity, and the cavity limits the lifting base 14 and the wedge block 15.

[0031] refer to Figure 4 The bottom of the lifting base 14 has a slide groove 141, and the depth of the slide groove 141 gradually becomes shallower along the sliding direction of the bottom plate 1, so that the shape of the slide groove 141 is wedge-shaped, which is matched with the wedge block 15. The top surface of the slide groove 141 is an inclined surface, and the upper surface of the wedge block 15 is also an inclined surface. Since the lifting base 14 is limited in front, back, left and right, when the wedge block 15 slides along the slide groove 141, it will drive the lifting base 14 to move up and down, thereby realizing the adjustment of the height of the product to be processed.

[0032] Two parallel guide bars 142 are formed on the inclined surface at the bottom of the slide groove 141, and the guide bars 142 extend obliquely downward along the inclined surface. At the same time, there are two guide grooves on the inclined surface of the wedge block 15 that match the guide bars 142. When the wedge block 15 slides, the guide bars 142 can slide along the guide grooves to play a guiding role, ensuring that the wedge block 15 will not move left and right, but can only slide along the slide groove 141. The bottom of the wedge block 15 will be embedded in the groove 101 on the upper part of the bottom plate 1, and the groove 101 can play a guiding role in the movement of the wedge block 15.

[0033] refer to Figure 1 A fixing seat 5 is provided at one end of the bottom plate 1 for mounting a driving mechanism. In this embodiment, the driving mechanism is a cylinder 6, because the driving force of the cylinder 6 is large and can drive the wedge block 15 to move. In other technical solutions, a driving component such as a cylinder can also be used.

[0034] The oil cylinder 6 is fixed horizontally on the fixing base 5, and the output end of the oil cylinder 6 passes through the baffle 8 and is fixedly connected to the wedge block 15. The expansion and contraction of the output end of the oil cylinder 6 drives the wedge block 15 to move, thereby driving the lifting base 14 to move up and down.

[0035] refer to Figure 2 A fixing plate 7 is vertically fixed at one end of the slide rail 4 away from the driving mechanism. A horizontally placed limiting rod 13 is arranged on the fixing plate 7. The limiting rod 13 will pass through the baffle plate 8 and be inserted into the avoidance groove 143. When the lifting base 14 moves upward, the position of the limiting rod 13 is fixed, and the limiting rod 13 will be exposed downward from the avoidance groove 143. At this time, if the wedge block 15 continues to move, the limiting rod 13 will block the wedge block 15, preventing the wedge block 15 from continuing to move, and limiting the movement of the wedge block 15. The horizontal position of the limiting rod 13 on the fixing plate 7 is adjustable, so the length of the limiting rod 13 extending into the avoidance groove 143 can be adjusted, thereby adjusting the position of the wedge block 15.

[0036] refer to Figure 5 The support plate 2 is located on the top of the lifting base 14 and can slide along the lifting base 14, and the sliding direction is perpendicular to the sliding direction of the bottom plate 1 (i.e., the Y-axis direction of the thread rolling machine). The two sides of the support plate 2 are protruded outward to form a pressing part 201, and the upper surface of the pressing part 201 is an inclined surface. At the same time, a pressing plate 10 is provided on each side of the support plate 2, and a plurality of mounting holes are opened on the pressing plate 10. A pressing bolt is provided in each mounting hole, and the pressing bolt passes through the mounting hole and is threadedly connected to the lifting base 14.

[0037] When the position of the support plate 2 is adjusted, the pressing bolts are rotated to drive the pressing plate 10 downward, and the pressing plate 10 applies downward pressure to the pressing parts 201 on both sides of the support plate 2, thereby pressing the two sides of the support plate 2 to prevent the support plate 2 from moving. Since the upper surface of the pressing part 201 is an inclined surface, the two pressing plates 10 can play a role in centering the support plate 2 when pressing downward, so that the support plate 2 will not deviate left or right.

[0038] A mounting groove 202 is provided on the upper part of the support plate 2, and a mounting plate 11 is installed in the mounting groove 202, and the mounting plate 11 is fixed in the mounting groove 202 by bolts. The mounting plate 11 is used to install the adjustment support seat 3, and the top of the adjustment support seat 3 is upwardly protruded to form a mounting portion with one side as a vertical surface, and the vertical surface of the mounting portion and the horizontal surface of the top of the adjustment support seat 3 together constitute a right-angled platform for installing and fixing other auxiliary positioning components for positioning the product to be processed. A plurality of through mounting holes are provided on the mounting portion, which are used to fix the auxiliary positioning components by bolts. The plurality of mounting holes are linearly and evenly spaced, so that the position of the auxiliary positioning components can be adjusted. At the same time, limit members 12 are provided on both sides of the adjustment support seat 3, and the limit members 12 are fixed to the support plate 2 by bolts, and the two limit members 12 can limit the adjustment support seat 3.

[0039] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the utility model. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the utility model and fall within the protection scope of the utility model.
