Description

Technical Field

[0001] The utility model relates to the technical field of screw rod straightening, in particular to a straightening machine for an electric guide rail screw rod. Background Art

[0002] The electric guide screw rod undergoes heat treatment, that is, it will bend and deform after high-temperature heating. The cutting stress during rough and fine machining will also cause the screw rod to bend and deform. To eliminate the bending deformation, it must be straightened by external pressure to ensure the accuracy requirements of fine machining.

[0003] A straightening machine is usually used to eliminate bending deformation of the screw rod, but existing straightening machines mostly support the two ends of the screw rod through rollers. When the middle part of the screw rod is subjected to force, the middle part bends, and the two ends will have a certain degree of warping. At the same time, the two ends of the screw rod have a tendency to shrink toward the middle, which will cause the two ends of the screw rod to slide relative to each other along the axis of the roller and the outer wall of the roller, generating friction. At the same time, the two ends of the screw rod are warped, which increases the friction between the screw rod and the roller, and easily causes the screw rod to wear.

[0004] In order to solve the above problems, we proposed a straightening machine for electric guide rail screw. Utility Model Content

[0007] In the above-mentioned straightening machine for electric guide rail screw, the pressure mechanism includes a mounting sleeve fixedly arranged at the upper end of the support frame, a press is fixedly arranged in the mounting sleeve, a pressure block is fixedly connected to the driving end of the press, and the pressure block is vertically aligned with the slide rail.

[0008] In the above-mentioned straightening machine for electric guide rail screw, support legs are provided at both left and right ends of the support rod, and two positioning plates are symmetrically provided at the bottom ends of the support legs, and positioning holes are provided on the positioning plates.

[0009] In the above-mentioned electric guide rail screw straightening machine, a fastening mechanism is arranged on the extension plate located on the front side of the support rod, and the fastening mechanism includes a threaded hole opened on the extension plate, a stud is screwed into the threaded hole, and the outer end of the stud is fixedly connected to a handle located on the outside of the extension plate.

[0012] Compared with the existing technology, the advantages of this electric guide rail screw straightening machine are:

[0013] The two ends of the screw rod are placed on two support plates respectively, and then the screw rod is squeezed and straightened by a press.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 4 A straightening machine for an electric guide rail screw comprises a support rod 1, which is arranged horizontally. A horizontal slide rail 2 having the same length as the support rod 1 is fixedly connected to the upper side wall of the support rod 1. Two support mechanisms are slidably arranged on the slide rail 2. The support mechanism comprises a sliding sleeve 3 which is slidably arranged on the slide rail 2. Both ends of the sliding sleeve 3 are fixedly connected to extension plates 4 extending downward. The two extension plates 4 are located at the front and rear sides of the support rod 1. A connecting plate 5 is fixedly arranged on the upper side wall of the sliding sleeve 3. Both front and rear ends of the connecting plate 5 are fixedly connected to vertically upward fixing plates 6. The outer walls of the fixed plates 6 are each provided with a slide groove 7, which is in the shape of a horizontal strip. The slide groove 7 runs through the front and rear outer walls of the fixed plates 6, and the inner walls of the slide groove 7 are smoothly arranged. A support plate 8 is arranged between the two fixed plates 6, and the support plate 8 is in a U-shape. An anti-slip pad is arranged on the U-shaped inner wall of the support plate 8. The support plate 8 is used to place the end of the screw rod to play a supporting role. Two support shafts 9 are symmetrically fixed to the outer wall of the support plate 8 at the front and back. The support shafts 9 are slidably inserted in the corresponding slide groove 7, and the support plate 8 can rotate and slide along the slide groove 7 through the support shaft 9.

[0021] The rear side wall of the support rod 1 is fixedly connected with a vertically upward support frame 10, and a pressure mechanism is arranged on the support frame 10. The pressure mechanism includes a mounting sleeve 11 fixedly arranged at the upper end of the support frame 10, and a press machine 12 is fixedly arranged in the mounting sleeve 11. The press machine 12 is vertically arranged and the driving end is vertically downward. The driving end of the press machine 12 is fixedly connected with a pressure block, and the pressure block is vertically aligned with the slide rail 2 for extruding and straightening the screw rod. Support legs 13 are arranged at the left and right ends of the support rod 1, and two positioning plates 14 are symmetrically arranged at the bottom end of the support leg 13. Positioning holes are opened on the positioning plates 14, and the positioning holes can be used to fix the positioning plates 14 to the ground, thereby improving the stability of the support rod 1.

[0022] A fastening mechanism is provided on the extension plate 4 located on the front side of the support rod 1, and the fastening mechanism includes a threaded hole opened on the extension plate 4, a stud 15 is screwed into the threaded hole, and the outer end of the stud 15 is fixedly connected to a handle 16 located on the outer side of the extension plate 4. After tightening the handle 16, the inner end of the stud 15 is squeezed on the support rod 1, so that the extension plate 4 is fixed, and then the sliding sleeve 3 is fixed. When the handle 16 is loosened, the two fastening mechanisms can be slidably adjusted so that the support plates 8 on the two fastening mechanisms respectively correspond to the two ends of the screw rod to be straightened.

[0023] The two ends of the screw rod are respectively placed on two support plates 8, and then the screw rod is squeezed and straightened by a press 12. When the two ends of the screw rod are tilted up by force, the support shaft 9 on the support plate 8 rotates in the slide groove 7 on the fixed plate 6 to keep the support plate 8 and the screw rod in contact. At the same time, when the two ends of the screw rod shrink toward the middle, the support shaft 9 slides in the slide groove 7, and the support plate 8 will also move with the end of the screw rod, avoiding relative sliding between the screw rod and the support plate 8, thereby avoiding wear of the screw rod.
