Description

Technical Field

[0001] The utility model relates to the field of parts processing equipment, in particular to a tool holder for machining end face deep grooves on a vertical lathe. Background Art

[0002] Turning tools are tools for turning, and are mainly used to turn parts on lathes. Turning tools are widely used in machinery manufacturing, aerospace, automobile manufacturing, mold processing and other fields.

[0003] With the development of industry, industrial equipment parts tend to be larger. At present, a certain type of ring forging needs to be machined with a very deep end face groove on its end face, with a depth of 400-500mm and a groove width of only 120mm. At present, the tool length limit is basically 350mm. If the tool length is increased on this basis, the bending moment generated by turning is large, and the tool bar of the overly long tool has insufficient rigidity. The bending moment is easy to exceed the force limit of the tool, which will cause the tool to vibrate or even break.

[0004] In addition, the iron chips generated by turning will accumulate in the end face groove, which is prone to tool vibration during the processing. In severe cases, it may even cause the tool to break. As a result, the current turning tools are not capable of processing grooves with a depth reaching a certain limit.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0006] Aiming at the deficiencies of the prior art, the utility model discloses a tool holder for machining end face deep grooves on a vertical lathe.

[0007] The technical solution adopted by the utility model is as follows:

[0008] A tool holder for machining end face deep grooves on a vertical lathe comprises a tool holder body, a turning tool and a chip guide mechanism, wherein the turning tool is adjustably mounted at the bottom of the tool holder body, the chip guide mechanism is mounted on the front side of the tool holder body, the chip guide mechanism comprises a bracket and a chip guide plate, the bracket is detachably connected to the tool holder body, and the chip guide plate is obliquely arranged on the bracket.

[0009] Furthermore, a fixing groove arranged along the height direction is opened at the bottom of the tool holder body, and the turning tool is fixed in the fixing groove.

[0010] Furthermore, a row of positioning holes is opened on one side of the tool holder body along the height direction, and the positioning holes are connected to the fixing grooves. Bolts are inserted into the positioning holes to fix the turning tool.

[0011] Furthermore, the chip guide plate is configured to be arc-shaped, and the arc of the chip guide plate gradually increases from bottom to top.

[0012] Furthermore, wing plates are evenly arranged on the top and bottom of the bracket.

[0013] Furthermore, the wing plate is provided with a slot arranged along its length direction, and the tool holder body is provided with a limit screw, and the limit screw penetrates into the slot.

[0014] Furthermore, the card slot is configured as a waist-shaped slot.

[0015] Furthermore, the number of the positioning holes is at least two.

[0016] The beneficial effects of the utility model are as follows:

[0017] 1. The turning tool can change the length of the tool holder body extending out from the bottom, so that the turning tool can reach a deeper turning position. When the end face groove is processed to a deep depth, the iron chips generated will fall into the end face groove. The chip guide plate shovels the iron chips out of the end face groove as the turning tool moves. While the turning work is in progress, the iron chips are effectively cleaned out to ensure the smooth progress of the turning work. There is no need to stop the machine to clean the iron chips, which is conducive to more convenient processing of the end face groove. The chip guide plate removes the iron chips and also reduces the contact between the iron chips and the turning tool, avoiding overheating and tool vibration caused by the friction between the turning tool and the iron chips, and improving the quality and qualified rate of the turned products.

[0018] 2. When the turning tool is turning, the fixed groove can block the turning tool and limit the vibration of the turning tool.

[0019] 3. Fix the turning tool by inserting bolts into the positioning holes. Positioning holes of different heights correspond to different turning tool installation heights, so as to increase the effective use depth of the turning tool when the turning tool length is fixed.

[0020] 4. The chip guide plate is spiral from bottom to top, using the centrifugal force generated when the ring rotates to guide the iron chips upward and outward, quickly discharging the iron chips to avoid excessive accumulation of iron chips in the groove.

[0021] 5. During the processing, the tool holder body moves downward and left and right, and the slot, i.e., the waist-shaped slot, is used to limit the range of movement of the tool holder body. When it moves to the extreme position, the limit screw abuts against the end of the slot to prevent the tool holder body from exceeding the set range of movement. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Example:

[0029] A tool holder for machining deep grooves on a vertical lathe, such as Figure 1 As shown, it includes a tool holder body 1, a turning tool 2 and a chip guide mechanism 3, wherein the turning tool 2 is adjustably mounted at the bottom of the tool holder body 1, and the chip guide mechanism 3 is mounted on the front side of the tool holder body 1. When in use, the tool holder body 1 is mounted on a machine tool, and the turning tool 2 turns iron chips on the end face of the part, which are cleaned out from the end face groove by the chip guide mechanism 3.

[0030] like Figure 1 As shown, a protrusion 11 is provided on the top of the tool holder body 1. The protrusion 11 and the tool holder body 1 are formed in one piece. The protrusion 11 can be inserted into the tool holder of the machine tool to achieve a quick connection between the two.

[0031] like Figure 1As shown, a fixing groove 12 arranged along the height direction is opened at the bottom of the tool holder body 1, and a turning tool 2 can be adjustably installed in the fixing groove 12, and the length of the turning tool 2 extending out of the fixing groove 12 can be changed according to the groove depth required for processing. During processing, the tool holder body 1 can penetrate into the deep groove with the turning tool 2, which in disguised form extends the length of the turning tool 2 so that it can exceed the deep groove of the length of the turning tool 2.

[0032] like Figure 1 As shown, a row of positioning holes 13 are opened along the height direction on one side of the tool holder body 1, and the positioning holes 13 are connected to the fixing groove 12. In this embodiment, three positioning holes 13 are provided, and the positioning holes 13 are selected as countersunk holes. When fixing the turning tool 2, bolts are inserted into the positioning holes 13 of the corresponding height, and the bolts fix the turning tool 2. When the turning tool 2 is fixed and the extension length of the turning tool 2 needs to be adjusted, the contact locking is first performed, and then the operator retracts the turning tool 2 to a suitable height, and finally the bolts are screwed into the positioning holes 13 of the corresponding height to fix it.

[0033] like Figure 2 As shown, the chip guide mechanism 3 includes a bracket 31 and a chip guide plate 33. The bracket 31 is detachably connected to one side of the tool holder body 1, and the chip guide plate 33 is tiltedly arranged on the bracket 31. During processing, the iron chips generated by the turning tool 2 will remain in the deep groove. The iron chips are guided upward and outward through the chip guide plate 33 by the centrifugal force generated when the ring rotates, and the iron chips move along the upper surface of the chip guide plate 33, so that the iron chips in the deep groove are quickly discharged.

[0034] like Figure 2 As shown, the chip guide plate 33 is provided with an arc shape, and the chip guide plate 33 is turned outward. During the turning process, the machined ring rotates together with the lathe chuck. During the relative movement between the machined part and the chip guide mechanism, the iron chips are accumulated in front of the chip guide mechanism. The iron chips continue to move upward along the surface of the chip guide plate 33, and then slide outward along the turned-out surface to prevent the iron chips from falling into the groove again. The width of the chip guide plate 33 is 3 to 8 mm smaller than the single side of the turned groove. This distance can prevent the iron chips from being missed, and can also prevent the chip guide plate 33 from contacting the workpiece body to produce scratches or abnormal noises.

[0035] like Figure 2 As shown, the top and bottom of the bracket 31 are evenly provided with wing plates 32. The wing plates 32 are provided with slots 321 arranged along the length direction thereof. The slots 321 are waist-shaped slots. The chip guide mechanism can move freely within the waist-shaped hole range relative to the tool holder to adapt to the arc-shaped deep groove on the end face of the workpiece. The tool holder body 1 is provided with a limit screw 322, which penetrates into the slot 321. The limit screw 322 plays a role of limiting. When the tool holder body 1 moves to the limit position, the limit screw 322 abuts against the end of the slot 321 to avoid exceeding the set range of movement.

[0036] Specific working process:

[0037] like Figure 2 and Figure 3 As shown, first, the tool holder body 1 is fixed to the tool holder of the vertical lathe by bolts, and the tool holder can move up and down in the vertical direction and move left and right in the horizontal direction. The chip guide mechanism 3 is also installed on the tool holder body 1, and the bracket 31 is fixed to the tool holder body 1 by the limit screw 322. The turning tool 2 is fixed in the fixing groove 12, and the chip guide plate 33 is located on one side of the turning tool 2. Then the workpiece is fixed to the machine chuck using the claws.

[0038] After the workpiece and the turning tool 2 are fixed, the machine tool is started, the workpiece rotates counterclockwise, and the deep groove turning of the end face of the workpiece is performed according to the program. During operation, the turning tool 2 and the chip guide plate 33 are both located in the deep groove of the end face of the workpiece. The turning tool 2 contacts the bottom of the deep groove of the end face of the workpiece to complete the turning. The iron chips generated by the turning will accumulate on the back of the tool holder, and the iron chips will be discharged from the deep groove along the arc-shaped chip guide plate 33 to avoid overheating and tool jamming caused by excessive contact between the iron chips and the turning tool 2. The tool holder can be used to work on the original equipment without the need for additional modification or additional steps to clear the iron chips, while improving processing efficiency and achieving the goal of reducing costs and increasing efficiency for the enterprise.

[0039] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
