Description

Technical Field

[0001] This utility model relates to the field of angle head technology, specifically to a structure for an angle head positioning block sleeve. Background Technology

[0002] In CNC milling, some parts cannot be machined using existing equipment or are impossible to machine due to objective constraints (fixtures, pressure plates, or other limitations). In these cases, an angle head is used to change the direction of the tool axis, converting the tool axis from vertical to horizontal. The angle head needs to be fixed to the machine tool spindle by a locating block to achieve its function. The locating block is fixed to the spindle with bolts, while the angle head is installed in the spindle and its rotation is restricted by a locating pin that engages with the locating block.

[0003] Currently, most positioning blocks used in the market are slotted or round hole shaped, but this requires high accuracy in the installation position of the positioning block, which limits the range of machine tools that the positioning block is applicable to. In addition, there is wear between the positioning block and the positioning block, which leads to the need to replace the positioning block regularly. Therefore, we need to propose a structure for the angle head positioning block insert. Utility Model Content

[0004] The purpose of this utility model is to provide a structure for an angle head positioning block sleeve. By setting a nested positioning block, a positioning sleeve is embedded in the positioning block. The sleeve is interference-fitted with the positioning pin, which facilitates the quick installation of the positioning pin and reduces wear between the positioning pin and the positioning block. This avoids damage and replacement of the positioning block and reduces the replacement cycle of the positioning block, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a structure for an angle head positioning block insert, comprising:

[0006] The positioning block and the positioning pin inserted into the positioning block are provided. The lower surface of the positioning block has an installation hole for the positioning pin to be inserted, and a positioning sleeve is embedded in the installation hole. The upper end of the positioning sleeve has a screw hole, and a first screw that is threadedly connected to the screw hole is inserted into the upper surface of the positioning block.

[0007] Preferably, the inner diameter of the positioning sleeve is smaller than the upper outer diameter of the positioning pin, and the outer diameter of the positioning sleeve is smaller than the outer diameter of the mounting hole.

[0008] Preferably, it also includes a machine tool spindle, a half sleeve is installed on the lower outer side of the machine tool spindle, the lower surface of the half sleeve has multiple sets of bottom holes, the upper surface of the positioning block is integrally formed with an extension seat that fits with the half sleeve, and two sets of second screws that are bolted to the half sleeve are inserted into the extension seat.

[0009] Preferably, a tool holder is installed at the lower end of the machine tool spindle, an angle head body is installed at the lower end of the tool holder, and a rotating ring is provided at the upper end of the angle head body and the lower end of the tool holder.

[0010] Preferably, the lower end of the positioning pin is inserted with two sets of third screws, and the positioning pin is fixedly connected to the outside of the rotating ring by the two sets of third screws, and the inner cavity of the positioning pin is hollow.

[0011] Preferably, a floating inner rod is slidably disposed inside the positioning pin, and the floating inner rod is T-shaped, with one end of the floating inner rod inserted into the rotating ring.

[0012] Preferably, the upper surface of the positioning block is provided with two sets of vent holes, and both sets of vent holes are connected to the mounting holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model mainly utilizes the cooperation between the positioning block, mounting hole, positioning sleeve, and positioning pin. By inserting the positioning sleeve into the positioning block and using the interference fit between the positioning sleeve and the mounting hole, the installation stability of the positioning sleeve is ensured. At the same time, the interference fit between the positioning pin and the mounting sleeve ensures the stability of the positioning pin installed on the positioning block. Furthermore, the positioning sleeve is further tightened by the first screw, thereby preventing the positioning sleeve from loosening. This avoids direct wear of the positioning pin on the positioning block during long-term use. The service life of the positioning block can be extended simply by replacing the positioning sleeve, reducing the overall machining cost of the lathe. Moreover, the positioning sleeve is easy to replace, reducing the replacement cycle of the positioning block. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a structure for an angle head positioning block 5 with a sleeve, comprising:

[0023] The positioning block 5 and the positioning pin 10 inserted into the positioning block 5 are provided. The lower surface of the positioning block 5 has an installation hole 51 for the positioning pin 10 to be inserted, and a positioning sleeve 8 is embedded in the installation hole 51. The upper end of the positioning sleeve 8 has a screw hole. The upper surface of the positioning block 5 is fitted with a first screw 6 that is threadedly connected to the screw hole. It is worth noting that before the positioning sleeve 8 is installed into the installation hole 51, glue needs to be applied to the inner wall of the installation hole 51 to further improve the stability of the installation of the positioning sleeve 8.

[0024] The inner diameter of the positioning sleeve 8 is smaller than the upper outer diameter of the positioning pin 10, and the outer diameter of the positioning sleeve 8 is smaller than the outer diameter of the mounting hole 51.

[0025] Specifically, by using an interference fit to install the positioning sleeve 8 and the positioning pin 10, the stability of the positioning sleeve 8 installed on the positioning block 5 can be ensured, and the stability of the positioning pin 10 inserted into the positioning sleeve 8 can also be ensured.

[0026] It also includes a machine tool spindle 1, a half sleeve 4 is installed on the lower outer side of the machine tool spindle 1, multiple sets of bottom holes are opened on the lower surface of the half sleeve 4, and an extension seat that fits with the half sleeve 4 is integrally formed on the upper surface of the positioning block 5, and two sets of second screws 7 that are bolted to the half sleeve 4 are inserted on the extension seat.

[0027] Secondly, the half sleeve 4 facilitates the quick fastening of the machine tool spindle 1 and the positioning block 5. The extension seat (not shown in the figure) and the second screw 7 on the positioning block 5 facilitate the installation and removal of the positioning block 5 on the half sleeve 4, further realizing a stable connection between the positioning block 5 and the machine tool spindle 1 and ensuring the positional stability of the positioning block 5 during operation. The multiple sets of bottom holes on the lower surface of the half sleeve 4 can flexibly adjust the installation position of the positioning block 5, enhancing the versatility of the structure.

[0028] A tool holder 2 is installed at the lower end of the machine tool spindle 1, and an angle head body 3 is installed at the lower end of the tool holder 2. A rotating ring 11 is provided at the upper end of the angle head body 3 and the lower end of the tool holder 2. The machine tool spindle 1, tool holder 2, and angle head body 3 are connected sequentially from top to bottom to form a complete angle head transmission chain, ensuring stable power transmission. The rotating ring 11 allows the angle head body 3 to rotate relative to the tool holder 2, providing a basis for angle adjustment of the angle head and meeting different machining angle requirements.

[0029] The lower end of the positioning pin 10 is inserted with two sets of third screws, and the positioning pin 10 is fixedly connected to the outside of the rotating ring 11 by the two sets of third screws. The inner cavity of the positioning pin 10 is hollow. The positioning pin 10 is fixed to the rotating ring 11 by the third screws (not shown in the figure), which makes the connection firm and easy to disassemble and maintain.

[0030] A floating inner rod 9 is slidably provided inside the positioning pin 10, and the floating inner rod 9 is T-shaped. One end of the floating inner rod 9 is inserted into the rotating ring 11. The floating inner rod 9 can play a buffering and guiding role in the connection between the positioning pin 10 and the rotating ring 11, compensate for assembly errors or small displacements during operation, avoid structural wear caused by rigid contact, and extend the service life of the component.

[0031] The upper surface of the positioning block 5 is provided with two sets of vent holes 12, and both sets of vent holes 12 are connected to the mounting hole 51. The connection between the two sets of vent holes 12 and the mounting hole 51 can balance the air pressure in the mounting hole 51, avoid the resistance caused by the air pressure difference when the positioning sleeve 8 is inserted or pulled out, and facilitate the disassembly of the positioning sleeve 8 by using the ejector pin when replacing the positioning sleeve 8, thereby improving the efficiency of replacing the positioning sleeve 8.

[0032] In use, by applying a layer of glue into the positioning hole of the positioning block 5, the positioning sleeve 8 is inserted into the mounting hole 51, and the first screw 6 is used to connect the positioning block 5 and the positioning sleeve 8 through the screw hole, thereby improving the stability of the positioning sleeve 8 fixed in the mounting hole 51 of the positioning block 5.

[0033] At this time, the positioning pin 10 is inserted into the opening of the positioning sleeve 8 and is interference-fitted with the positioning sleeve 8, thereby completing the installation of the angle head body 3. Since the positioning block 5 is made of moderate hardness and is easy to process, while the positioning pin 10 is made of a material harder than the positioning sleeve 8, the positioning sleeve 8 needs to be replaced after a period of time. Replacing the positioning block 5 increases the processing cost, while the positioning sleeve 8 is easy to disassemble and replace by passing through the vent hole 12 with an auxiliary pin, and the processing cost is low. Replacing the positioning sleeve 8 reduces the cost compared to replacing the positioning block 5.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
