Description

Technical Field

[0001] This utility model belongs to the field of forklift drilling technology, and in particular relates to a forklift forklift drilling device with a positioning structure. Background Technology

[0002] The forklift carriage, also known as the attachment carriage, is a frame-shaped structure that bears longitudinal and lateral loads and is used to mount forks, guides, or other attachments. It consists of upper and lower crossbeams, a backrest, and a guide wheel frame. The forklift mainly consists of a forklift carriage with fork arms and a lifting mechanism that drives the forklift carriage to rise and fall.

[0003] The forklift carriage needs to be assembled with multiple components such as forks, rollers, and chains in the entire forklift system. Drilling provides precise installation positions for these components. To fix the position of the forklift carriage during drilling, a forklift carriage drilling device with a positioning structure has been designed. This device mainly uses a threaded rod and a pressure plate to press and fix the forklift carriage. At the same time, the support tube and positioning structure can flexibly adjust the initial height of the pressure plate to make flexible adjustments for different specifications of forklift carriages. This fixes the position of the forklift carriage during drilling, preventing the forklift carriage from shaking during drilling and causing errors in the drilling position. Utility Model Content

Detailed Implementation

[0023] In the following description, embodiments of the forklift fork drilling device with positioning structure of the present invention will be described with reference to the accompanying drawings.

[0024] Example 1:

[0025] Figure 1-5 This invention illustrates a forklift fork drilling device with a positioning structure according to an embodiment of the present invention. It includes: two L-shaped support legs 2 fixedly connected to the left and right sides of the bottom of a drilling lathe 1 by bolts; support rods 3 fixedly connected to the tops of both L-shaped support legs 2 by bolts; support plates 4 welded to the tops of the support rods 3; support tubes 5 slidably connected to the surface of the support rods 3; multiple positioning holes 6 opened on the surface of the support tubes 5; threaded holes opened on the surface of the support rods 3; bolts 7 threadedly connected to the threaded holes and positioning holes 6; U-shaped plates 8 welded to the front and rear sides of the inner cavity of the support tubes 5; a positioning structure 9 provided in the inner cavity of the support tubes 5; and a transverse plate 10 fixedly connected to the tops of the two support tubes 5 by bolts. A screw tube is installed on the surface, and a threaded rod 11 is threadedly connected to the inner cavity of the screw tube. A pressing plate 12 is rotatably connected to the bottom end of the threaded rod 11. The positioning structure 9 includes a semi-circular hole 91 opened in the inner cavity of the U-shaped plate 8. Positioning tubes 92 are welded to both the front and rear sides of the support plate 4. The two positioning tubes 92 are evenly close to the top of the support plate 4. A ring 93 is slidably connected to the inner cavity of the positioning tube 92. A spring 94 is welded between the ring 93 and the inner cavity of the positioning tube 92. Two guide rods 13 are welded to the top of the pressing plate 12. By setting the guide rods 13, the pressing plate 12 can obtain a vertical guiding force during the sliding process, so that the pressing plate 12 can keep sliding downward in a straight line and avoid the pressing plate 12 from rotating.

[0026] Example 2:

[0027] Figure 1-5This invention illustrates a forklift fork drilling device with a positioning structure according to an embodiment of the present invention. It includes: two L-shaped support legs 2 fixedly connected to the left and right sides of the bottom of a drilling lathe 1 by bolts; support rods 3 fixedly connected to the top of each of the two L-shaped support legs 2 by bolts; support plates 4 welded to the top of the support rods 3; support tubes 5 slidably connected to the surface of the support rods 3; multiple positioning holes 6 opened on the surface of the support tubes 5; threaded holes opened on the surface of the support rods 3; bolts 7 threadedly connected to the threaded holes and positioning holes 6; U-shaped plates 8 welded to the front and rear sides of the inner cavity of the support tubes 5; a positioning structure 9 provided in the inner cavity of the support tubes 5; and the two support tubes 5... A horizontal plate 10 is bolted to the top. A threaded tube is installed on the surface of the horizontal plate 10. A threaded rod 11 is threaded to the inner cavity of the threaded tube. A pressure plate 12 is rotatably connected to the bottom end of the threaded rod 11. A ball bearing 95 is rotatably connected to the inner cavity of the ring 93. The surface of the ball bearing 95 is rolled to the inner cavity of the semi-circular hole 91. Two circular holes are opened at the top of the horizontal plate 10. A guide rod 13 is slidably connected to the inner cavity of the circular holes. A rotating wheel 14 is welded to the top of the threaded rod 11. The rotating wheel 14 provides a point of leverage for the operator during the rotation of the threaded rod 11, making it easier for the operator to rotate the threaded rod 11.

[0028] Working principle: When using this utility model, the user pulls or pushes the support tube 5 to slide on the surface of the support rod 3, which in turn causes the inner cavity of the U-shaped plate 8 to slide on the surface of the ball bearing 95. At this time, under the positioning of the support plate 4 and the support of the positioning tube 92, the surface of the ball bearing 95 will roll in the inner cavity of the U-shaped plate 8. Then, under the rebound action of the spring 94, the ball bearing 95 rolls into the inner cavity of the semi-circular hole 91, thereby positioning the position of the support tube 5. This allows the position of the positioning hole 6 to be more quickly aligned with the position of the screw hole. Subsequently, the rotating wheel 14 drives the threaded rod 11 to rotate, which in turn presses the pressing plate 12 downward, thereby pressing and fixing the fork frame. This fixes the position of the fork frame during the drilling process, preventing the fork frame from shaking during drilling and causing errors in the drilling position.

[0029] In summary, this forklift fork drilling device with a positioning structure rotates the rotating wheel 14 to drive the threaded rod 11 to rotate, which in turn pushes the pressing plate 12 downward, thereby pressing and fixing the forklift. This achieves the purpose of fixing the position of the forklift during the drilling process, so as to avoid the forklift from shaking during the drilling process and causing errors in the drilling position.
