Description

Technical Field

[0001] The utility model relates to the technical field of table drilling machine accessories, in particular to a material limiting mechanism for a table drilling machine. Background Art

[0002] A drilling machine can drill holes in workpieces. A drilling machine generally includes a base, a drilling machine body that is lifted and lowered with the base, a motor and a drill bit driven by the motor, a driver (such as a cylinder) that drives the drilling machine body up and down, and a support plate between the drilling machine body and the base. When processing the accessories of the reamer (such as opening holes for fixings), a desktop drilling machine is required.

[0003] The applicant believes that:

[0004] When a bench drill is drilling a material below, it is generally necessary to perform an initial limit on the material to ensure that the material will not shift during drilling. The existing bench drill limiter has a drilling hole itself. The material is held against the inside of the limiter with a finger, and then the bench drill is rotated downward through the preset drilling hole to quickly drill the material. However, when this limiter is used, the staff is required to manually hold the material against the inner wall of the limiter before drilling can be performed. Therefore, the user's hand will be under the equipment, increasing the risk of operation. Utility Model Content

[0005] The utility model aims to provide a material limiting mechanism for a desktop drilling machine to solve the problem in the background art that drilling can only be performed when the material is attached to the inner wall of the limiter, so the user's hands will be under the equipment, increasing the risk of operation.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A material limiting mechanism for a desktop drilling machine comprises an outer bracket, a positioning block and a driving component, wherein a positioning block is installed in the middle of the outer bracket, the driving component is arranged below the positioning block, and a limiting plate is arranged above the outer portion of the positioning block;

[0008] The driving component includes a driving wheel, a driving rod, a driving block and a connecting rod. The driving wheel is fixedly connected to the driving rod on one side close to the outer bracket. The driving block is sleeved on the outer wall of the driving rod. The connecting rod is fixedly connected to the outer wall above the driving block.

[0009] Furthermore, a mounting column is welded to the outer wall of the limiting plate.

[0010] Furthermore, sliding grooves are provided at corresponding positions of the outer bracket and the connecting rod.

[0011] Furthermore, two mounting slots are provided at positions corresponding to the outer bracket and the mounting column.

[0012] Furthermore, a material block is placed inside the outer bracket.

[0013] Furthermore, a fixing nut is installed on the outer wall of the mounting column.

[0014] Furthermore, the connecting rod is fixedly connected to the positioning block.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] 1. The utility model adds a positioning block on the basis of the material limiting mechanism. The positioning block is moved by a driving component, so the outer bracket and the positioning block can complete the overall limiting work of the material. The staff does not need to manually hold the material on one side, thereby effectively improving the safety of the mechanism itself.

[0017] 2. The outer wall of the outer bracket is provided with two sets of installation slots with different heights, so the limit plate can be installed at different heights, and thus is suitable for different types of material blocks. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0025] like Figure 1-4As shown, the present invention provides a material limiting mechanism for a table-type drilling machine, including an outer bracket 1, a positioning block 8 and a driving component 10. A positioning block 8 is installed in the middle of the outer bracket 1, and the driving component 10 is arranged below the positioning block 8. A limiting plate 2 is arranged above the outer portion of the positioning block 8. The purpose is that the present invention adds a positioning block 8 on the basis of the material limiting mechanism. The positioning block 8 is moved by the driving component 10, so the outer bracket 1 and the positioning block 8 can complete the overall limiting work of the material, and the staff does not need to manually hold the material on one side. When the rotary head of the bench drill moves downward, the staff's hand is no longer under the equipment, thereby effectively improving the safety of the mechanism itself;

[0026] like Figure 4 As shown, the driving component 10 includes a driving wheel 1001, a driving rod 1002, a driving block 1003 and a connecting rod 1004. The driving wheel 1001 is fixedly connected to the driving rod 1002 on one side close to the outer bracket 1. The driving block 1003 is sleeved on the outer wall of the driving rod 1002. The outer wall above the driving block 1003 is fixedly connected to the connecting rod 1004.

[0027] It should be noted that the driving rod 1002 is a screw structure, and the driving rod 1002 and the driving block 1003 are threadedly connected;

[0028] The specific implementation is as follows:

[0029] After the driving wheel 1001 is manually rotated, the driving rod 1002 rotates inside the bottom side of the outer bracket 1, and the driving block 1003 drives the upper positioning block 8 to move and work simultaneously through the connecting rod 1004.

[0030] As an implementation mode, a mounting column 4 is welded to the outer wall of the limiting plate 2, and the mounting column 4 itself can be used to assist the installation work.

[0031] As an implementation mode, a sliding groove 9 is provided at a position corresponding to the outer bracket 1 and the connecting rod 1004 , and an outer wall of the driving rod 1002 fits with an inner wall of the sliding groove 9 .

[0032] As an implementation manner, two mounting slots 7 are provided at positions corresponding to the outer bracket 1 and the mounting posts 4 , and the mounting slots 7 can be used for inserting the mounting posts 4 .

[0033] As an implementation manner, a material block 6 is placed inside the outer bracket 1, and the material block 6 is fixed in position by a preset drill hole 3 for drilling.

[0034] As an implementation manner, a fixing nut 5 is installed on the outer wall of the mounting column 4. The fixing nut 5 is installed on the outer wall of the mounting column 4 through a threaded structure, and can be used for fixing.

[0035] As an implementation mode, the connecting rod 1004 is fixedly connected to the positioning block 8 , and the sliding groove 9 limits the connecting rod 1004 , so that the connecting rod 1004 can move horizontally along the sliding groove 9 .

[0036] Working principle:

[0037] When the material limiting mechanism of the desktop drilling machine is in use, the limiting plate 2 is first installed in the mounting slot 7 of the outer bracket 1 through the mounting column 4, and then the fixing nut 5 is used to install itself, and then the material block 6 is placed inside the outer bracket 1. After the driving wheel 1001 is manually turned, the driving rod 1002 rotates inside the bottom side of the outer bracket 1, and the driving block 1003 will drive the upper positioning block 8 to move and work simultaneously through the connecting rod 1004, thereby limiting the material block 6, and finally starting the bench drill, and the drill bit drills downward through the drilling hole 3 to drill the material block 6.

[0038] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
