Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a drill press fixture holder. Background Technology
[0002] As the name suggests, a drilling machine fixture is a fixed tool used to process workpieces on a drilling machine. Its main function is to ensure the stability and accuracy of the workpiece during the processing. The workpiece is positioned in the fixture by using positioning elements instead of support points. However, both the positioning elements and the positioning reference of the workpiece have errors during manufacturing, which will affect the accuracy of the workpiece positioning.
[0003] In actual use, the following shortcomings were found in the existing drill press fixture holders:
[0004] Existing drilling machine fixtures apply downward pressure to press and clamp the workpiece through the clamping device. Sometimes, due to incorrect action sequence of the actuators, the ejection of the fixture auxiliary support precedes the clamping action of the pressure plate cylinder when the workpiece is clamped, causing the workpiece to bend and deform after clamping, affecting the flatness of the workpiece.
[0005] Existing drilling machine fixtures apply downward pressure to press and clamp the workpiece using a clamping device. However, due to the low friction between the fixture and the bottom of the workpiece, the workpiece may vibrate or deviate during processing. The workpiece is prone to shifting during processing, affecting the processing accuracy and thus the processing effect and quality.
[0006] Therefore, this application provides a drill press fixture to meet the requirements. Utility Model Content
[0007] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a drill press fixture holder.
[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0009] A drilling machine clamping base includes: a base, a base, a column, a frame, an adjusting rod, a handle, a screw, a clamping plate, a connecting rod, a fixing plate, a guide post, a guide bushing, a guide seat, a spring telescopic sleeve, a support column, and a rubber gasket. The base has bases on its upper left and right sides. The frame is mounted on the upper end of the base via the column. An adjusting rod is mounted on the top of the frame. A handle is mounted on the upper end of the adjusting rod. A screw, which is pulsatorically connected to the adjusting rod, is mounted on the lower inner side of the frame. A clamping plate is mounted on the bottom of the screw. A connecting rod is mounted on the upper end of the clamping plate. A fixing plate is mounted on the other end of the connecting rod. A guide post is mounted on the side of the fixing plate. A guide bushing is mounted on the bottom of the guide post. A guide seat is mounted on the side of the base. A buffer groove is provided inside the base. A spring telescopic sleeve is installed inside the buffer groove. A support column is mounted on the inner side of the spring telescopic sleeve. A rubber gasket is mounted on the top of the support column.
[0010] Preferably, connecting rods are vertically installed on the left and right sides of the upper end of the clamping plate, and the fixing plate is installed at the upper end of the clamping plate through the connecting rods.
[0011] Preferably, the fixing plate is parallel to the clamping plate, and the fixing plate extends laterally to the outer end of the side of the clamping plate.
[0012] Preferably, there are two sets of guide posts and guide bushings, and the two sets of guide posts and guide bushings are located at the lower ends of the sides on the left and right sides of the fixing plate.
[0013] Preferably, the guide post and guide bushing extend vertically downward to the lower end of the side of the clamping plate, the guide post and guide bushing are arranged opposite to the guide seat, and the guide post and guide bushing are fitted with the guide seat.
[0014] Preferably, the buffer groove is provided in four sets, and the four sets of buffer grooves are located at the four ends of the machine base, and the four sets of buffer grooves are located below the clamping plate.
[0015] Preferably, the spring telescopic sleeve and the support column are arranged vertically, and the support column extends vertically from the inside of the spring telescopic sleeve to the outer end of the spring telescopic sleeve.
[0016] Preferably, the rubber pad is circular, and the support column and the rubber pad extend outward from the buffer groove to the surface of the base.
[0017] Compared with the prior art, this utility model has at least the following beneficial effects:
[0018] 1. When the adjusting screw drives the clamping plate to move downward to clamp the workpiece on the machine base, the guide posts and guide bushings on the left and right sides of the upper fixing plate of the clamping plate can be inserted into the guide seat before the clamping plate contacts the workpiece. This guides the clamping force and buffers it, preventing the clamping support from pushing out before the clamping action of the pressure plate when the workpiece is clamped, thus effectively reducing the bending and deformation of the workpiece after clamping.
[0019] 2. When the workpiece is placed on the machine base, it is pressed into the buffer groove by the support column and rubber pad. The telescopic spring in the spring telescopic sleeve pushes the support column upward, applying pressure to the workpiece from below. The rubber pad is attached to the bottom of the workpiece, which can increase the friction between the workpiece and the rubber pad, reduce the vibration or deviation generated during the processing, and thus affect the processing effect and quality.

Detailed Implementation
[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The drill press clamp holder shown in this embodiment of the present invention includes: a base 1, a base 2, a column 3, a frame 4, an adjusting rod 5, a handle 6, a screw 7, a clamping plate 8, a connecting rod 9, a fixing plate 10, a guide column 11, a guide bushing 12, a guide seat 13, a spring telescopic sleeve 14, a support column 15, and a rubber gasket 16. The base 2 is provided on the left and right sides of the upper end of the base 1. The frame 4 is mounted on the upper end of the base 2 via the column 3. The adjusting rod 5 is mounted on the top of the frame 4, and a handle 6 is mounted on the upper end of the adjusting rod 5. A handle 6 is mounted on the lower inner side of the frame 4. The machine base 2 is equipped with a screw 7 that is connected to the adjusting rod 5 in a transmission manner. A clamping plate 8 is installed at the bottom of the screw 7. A connecting rod 9 is installed at the upper end of the clamping plate 8. A fixing plate 10 is installed at the other end of the connecting rod 9. A guide post 11 is installed on the side of the fixing plate 10. A guide bushing 12 is installed at the bottom of the guide post 11. A guide seat 13 is installed on the side of the base 2. A buffer groove 101 is provided inside the machine base 1. A spring telescopic sleeve 14 is installed inside the buffer groove 101. A support column 15 is installed on the inner side of the spring telescopic sleeve 14. A rubber gasket 16 is installed on the top of the support column 15.
[0029] In this embodiment, connecting rods 9 are vertically installed on the left and right sides of the upper end of the clamping plate 8, and the fixing plate 10 is installed at the upper end of the clamping plate 8 through the connecting rods 9. When the clamping plate 8 is moved downward by adjusting the screw 7 through the adjusting rod 5 to clamp the workpiece on the machine base 1, the guide posts 11 and guide bushings 12 on the left and right sides of the fixing plate 10 at the upper end of the clamping plate 8 can be inserted into the guide seat 13 before the clamping plate 8 contacts the workpiece.
[0030] In this embodiment, the fixing plate 10 is parallel to the clamping plate 8, and the fixing plate 10 extends laterally to the outer end of the side of the clamping plate 8, so that the clamping force applied by the fixing plate 10 and the clamping plate 8 remains parallel.
[0031] In this embodiment, two sets of guide posts 11 and guide bushings 12 are provided, and the two sets of guide posts 11 and guide bushings 12 are located at the lower ends of the sides on the left and right sides of the fixing plate 10.
[0032] In this embodiment, the guide post 11 and the guide bushing 12 extend vertically downward to the lower end of the side of the clamping plate 8. The guide post 11 and the guide bushing 12 are arranged opposite to the guide seat 13, and the guide post 11 and the guide bushing 12 are fitted with the guide seat 13. They can be inserted into the guide seat 13 before the clamping plate 8 contacts the workpiece, so as to guide the clamping force and buffer the clamping force.
