Description

Technical Field

[0001] This utility model relates to the field of auxiliary support technology, specifically to a compact, long-stroke auxiliary support mechanism. Background Technology

[0002] In machining, sometimes the workpiece's structure limits the machining area, causing it to be in a cantilevered state; or, to facilitate workpiece clamping, the machine tool fixture may not have enough fixed supports to ensure the workpiece's correct position, often leading to machining difficulties. To maintain workpiece stability and enhance rigidity during positioning, auxiliary supports are often used. These auxiliary supports should possess sufficient rigidity, helping the main supports withstand cutting forces without causing the workpiece to move away from the locating surface.

[0003] Currently, most auxiliary supports on the market are standard parts with fixed strokes, which sometimes fail to meet on-site requirements. Therefore, we propose a compact, long-stroke auxiliary support mechanism. Utility Model Content

[0004] The purpose of this invention is to overcome the aforementioned problems in the prior art and provide a compact, large-stroke auxiliary support mechanism that ensures sufficient stroke during use and allows for locking of any stroke, thereby effectively meeting on-site requirements.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0006] A compact, long-stroke auxiliary support mechanism includes an auxiliary support base. A pneumatic support rod is movably mounted on one end of the auxiliary support base via a mounting seat. A support head is connected to one end of the pneumatic support rod. A stroke locking mechanism that cooperates with the pneumatic support rod is installed on the end of the auxiliary support base close to the support head. A pneumatic seat is installed on the other end of the auxiliary support base, and the pneumatic seat is movably inserted into the other end of the pneumatic support rod.

[0007] The pneumatic base has a first stroke air passage, which is connected to the other end of the pneumatic support rod. The auxiliary support base has a second air passage. The rear side wall of the auxiliary support base has an air passage interface one and an air passage interface two. One end of the second air passage is connected to the first air passage, and the other end is connected to the third port of the first air passage. The second air passage is connected to the inner cavity of the auxiliary support base.

[0008] Preferably, the number of stroke locking mechanisms is two sets, one set is installed on the top of the auxiliary support, and the other set is installed on one side of the auxiliary support.

[0009] Based on the above technical features, two sets of stroke locking mechanisms are used to lock the pneumatic support rod after it has moved, preventing it from retracting and greatly improving the stability of the pneumatic support rod and support head during use.

[0010] Preferably, the stroke locking mechanism includes a locking cylinder, which is fixedly mounted on the auxiliary support base by screws. The power extension end of the locking cylinder is equipped with a locking head that mates with the outer surface of the pneumatic support rod. The cylindrical end of the mounting base has a displacement through hole two that mates with the locking head.

[0011] Based on the above technical features, it is convenient to provide power to drive the locking head to move closer to or away from the outer surface of the pneumatic support rod when the locking cylinder is working.

[0012] Preferably, the top and one side of the auxiliary support base are provided with displacement through holes that cooperate with the locking head; the top and one side of the auxiliary support base are provided with grooves that correspond to and communicate with the displacement through holes; a guide block is installed at the bottom of the groove; and a guide groove that cooperates with the guide block is provided on the outer surface of the locking head.

[0013] Based on the above technical features, when the locking head is driven by the locking cylinder to move closer to or away from the outer surface of the pneumatic support rod, the locking head is guided by the guide block to prevent it from rotating, so that the locking head can fit tightly against the outer surface of the pneumatic support rod when locking and limiting the pneumatic support rod.

[0014] Preferably, the auxiliary support base is provided with side blocks on both the front and rear sides, and the top extension direction of the side blocks is provided with a plurality of fixing and mounting holes.

[0015] Based on the above technical features, it is convenient to install and fix the auxiliary support on the tooling.

[0016] Preferably, a sealing groove is provided at the center of one side wall of the mounting base close to the support head, and a dustproof sealing ring is installed in the sealing groove; a second sealing ring is installed on both the outer and inner surfaces of the cylindrical end of the mounting base away from the sealing groove.

[0017] Based on the above technical features, the sealing performance between the mounting base and the auxiliary support base, as well as between the mounting base and the pneumatic support rod, is improved.

[0018] Preferably, the other end of the pneumatic support rod is a cavity structure, and a first sealing ring is installed on both the outside of the other end of the pneumatic support rod and the inside of the cavity.

[0019] Based on the above technical features, the sealing performance between the pneumatic support rod and the auxiliary support seat, as well as between the pneumatic support rod and the pneumatic seat, is improved.

[0020] Preferably, the pneumatic base is composed of two parts: a venting cylinder and a sealing positioning block. The first port of the first air passage is connected to the left side wall of the venting cylinder, the second port of the first air passage is connected to the right side wall of the sealing positioning block, and the fourth port of the first air passage is connected to the outer circumferential wall of the sealing positioning block.

[0021] The auxiliary support base has an air passage three at the bottom right side and an air interface three at the bottom. One end of the air passage three is connected to the air interface three. The air interface one, air interface two, and air interface three are respectively connected to an external air pipe. A pressure switch is installed on the air pipe connected to the air interface three.

[0022] Based on the above technical features, the combination of the air passage three and the pressure switch in the ventilated state facilitates the detection of whether the pneumatic support rod has finally reached its final position after retraction.

[0023] Preferably, the sealing positioning block has an air passage four, with one opening of the air passage four connected to the outer circumferential wall of the sealing positioning block, the other opening of the air passage four connected to the other end of the air passage three, the other opening of the air passage four connected to the left side wall of the sealing positioning block, and the other opening of the air passage four connected to the right side wall of the sealing positioning block; the second opening, the fourth opening, the first opening, and the fourth opening are used for sealing during operation.

[0024] Based on the above technical features, after the air passages 2 and 1 are ventilated, the gas can be delivered to the end cavity of the pneumatic support rod, thereby enabling the pneumatic support rod to be extended by air propulsion.

[0025] In summary, this utility model has at least one of the following beneficial effects:

[0026] This invention allows air to flow through air in port one and be cut off through air in port two. Air is then delivered to the pneumatic support rod via air channels one and two, causing it to extend and move the support head. Ultimately, the support head contacts and presses against the workpiece, completing a compact, large-stroke auxiliary support function. A stroke locking mechanism locks the extension of the pneumatic support rod after any movement. Cutting off air in air in port one and opening air in port two causes the pneumatic support rod to retract and reset, ensuring sufficient stroke for the auxiliary support mechanism to meet on-site requirements.

Detailed Implementation

[0040] The following is in conjunction with the appendix Figure 1-11 The present invention will be described in further detail below.

[0041] One embodiment of this utility model is shown below: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 10 A compact, long-stroke auxiliary support mechanism includes an auxiliary support base 1, one end of which is movably mounted with a pneumatic support rod 2 via a mounting base 4, and one end of the pneumatic support rod 2 is connected to a support head 3.

[0042] Mounting base 4 is fixed to auxiliary support base 1 with screws. A sealing groove is provided at the center of one side wall of mounting base 4 close to support head 3. A dustproof sealing ring 6 is installed in the sealing groove to seal and prevent dust, so that the pneumatic support rod 2 can move flexibly. A second sealing ring is installed on the outer and inner surfaces of the cylindrical end of mounting base 4 away from the sealing groove to improve the sealing between mounting base 4 and auxiliary support base 1 and between mounting base 4 and pneumatic support rod 2.

[0043] The auxiliary support base 1 is equipped with a stroke locking mechanism 9 that cooperates with the pneumatic support rod 2 at one end close to the support head 3. There are two sets of stroke locking mechanisms 9, one set is installed on the top of the auxiliary support base 1 and the other set is installed on one side of the auxiliary support base 1. The two sets of stroke locking mechanisms 9 are used to lock the pneumatic support rod 2 after it has moved, preventing it from retracting and greatly improving the stability of the pneumatic support rod 2 and the support head 3 during use.

[0044] A pneumatic seat 5 is installed at the other end of the auxiliary support seat 1. The pneumatic seat 5 is movably inserted into the other end of the pneumatic support rod 2. The other end of the pneumatic support rod 2 is a cavity structure. A first sealing ring is installed on the outside of the other end of the pneumatic support rod 2 and inside the cavity to improve the sealing between the pneumatic support rod 2 and the auxiliary support seat 1, as well as between the pneumatic support rod 2 and the pneumatic seat 5.

[0045] The pneumatic base 5 has a first stroke air passage 7, which is connected to the other end of the pneumatic support rod 2. The auxiliary support base 1 has a second air passage 8. The rear side wall of the auxiliary support base 1 has an air passage interface 101 and an air passage interface 102. One end of the second air passage 8 is connected to the first air passage interface 101, and the other end is connected to the third port 703 of the first air passage 7. The second air passage interface 102 is connected to the inner cavity of the auxiliary support base 1.

[0046] See Figure 3 The stroke locking mechanism 9 includes a locking cylinder 901, which is fixedly mounted on the auxiliary support base 1 by screws. The power extension end of the locking cylinder 901 is equipped with a locking head 902 that mates with the outer surface of the pneumatic support rod 2.

[0047] See Figure 6 , Figure 7The top and one side of the auxiliary support base 1 are provided with displacement through holes 104 that cooperate with the locking head 902. The outer surface of the cylindrical end of the mounting base 4 is provided with displacement through holes 401 that cooperate with the locking head 902. The displacement through holes 401 and 104 correspond to each other, so that the locking cylinder 901 can provide power to drive the locking head 902 to move closer to or away from the outer surface of the pneumatic support rod 2 when the locking cylinder 901 is working.

[0048] See Figure 6 The top and one side of the auxiliary support base 1 are provided with grooves 105, which are connected to the displacement through hole 104. A guide block 10 is installed at the bottom of the groove 105. The outer surface of the locking head 902 is provided with a guide groove 9021 that cooperates with the guide block 10. When the locking head 902 is driven by the locking cylinder 901 to move closer to or away from the outer surface of the pneumatic support rod 2, the guide block 10 guides the locking head 902 to prevent it from rotating, so that the locking head 902 can fit tightly with the outer surface of the pneumatic support rod 2 when locking and limiting the pneumatic support rod 2.

[0049] See Figure 8 The auxiliary support base 1 is provided with side blocks 103 on both the front and rear sides. Several fixing holes are opened in the top extension direction of the side blocks 103 to facilitate the installation and fixing of the auxiliary support base 1 on the tooling.

[0050] See Figure 3 , Figure 5 The pneumatic base 5 consists of two parts: a venting cylinder 501 and a sealing positioning block 502. The tail end of the auxiliary support base 1 has a fitting groove that mates with the sealing positioning block 502. The sealing positioning block 502 is fixedly installed in the fitting groove with screws, further facilitating the fixed installation of the pneumatic base 5 and the auxiliary support base 1. After fixed installation, it ensures that the first air passage 7 is connected to the second air passage 8 via the third port 703; the first port 701 of the first air passage 7 connects to the left side wall of the venting cylinder 501, allowing the pneumatic base 5 to be fixedly installed at the tail end of the auxiliary support base 1. Then, the air passage 7 is connected to the cavity structure at the other end of the pneumatic support rod 2; the second port 702 of the air passage 7 is connected to the right side wall of the sealing positioning block 502, and the fourth port 704 of the air passage 7 is connected to the outer circumferential wall of the sealing positioning block 502; the second port 702 and the fourth port 704 are sealed during operation, so that after air is introduced from the air passage interface 101, the gas is transported through the air passage 8 and the air passage 7, and finally the gas is transported to the tail cavity of the pneumatic support rod 2, so as to realize the pneumatic push of the pneumatic support rod 2 to make it extend;

[0051] See Figure 3 , Figure 5 , Figure 11An air passage 3 15 is provided at the bottom right side of the auxiliary support base 1, and an air interface 3 106 is provided at the bottom of the auxiliary support base 1. One end of the air passage 3 15 is connected to the air interface 3 106. Air interface 1 101, air interface 2 102, and air interface 3 106 are respectively connected to an external air pipe. A pressure switch is installed on the air pipe connected to the air interface 3 106.

[0052] The sealing positioning block 502 has an air passage 4 503. The first opening 11 of the air passage 4 503 connects to the outer circumferential wall of the sealing positioning block 502. The second opening 12 of the air passage 4 503 connects to the other end of the third opening 15. The third opening 13 of the air passage 4 503 connects to the left side wall of the sealing positioning block 502, and the fourth opening 14 of the air passage 4 503 connects to the right side wall of the sealing positioning block 502. The first opening 11 and the fourth opening 14 are connected during operation. The air passage pipe connected to the air passage interface 3 106 delivers gas from the air passage interface 3 106 to the air passage 3 15, and then delivers gas from the air passage 4 503 to the port 3 13. With the cooperation of the pressure switch, it is convenient to detect whether the pneumatic support rod 2 is finally in place after retraction (the side wall of the pneumatic support rod 2 away from the support head 3 is in contact with the left side wall of the sealing positioning block 502, which blocks the port 3 13 of the air passage 4 503, indicating that the pneumatic support rod 2 is in the retracted state).

[0053] Working principle:

[0054] Air is supplied to airway 101 through the airway 101-connected airway, while the airway 102-connected airway is shut off. Gas is then delivered to the pneumatic support rod 2 via airway 2-8 and airway 1-7, causing it to extend and move the support head 3. The locking cylinder 901 then moves the locking head 902 close to the outer surface of the pneumatic support rod 2. Finally, the locking head 902 presses and limits the outer surface of the pneumatic support rod 2, locking the extended pneumatic support rod 2 after any movement. This allows the support head 3 to contact and press against the workpiece, completing the compact, large-stroke auxiliary support operation. By shutting off air supply to airway 101 and opening air supply to airway 102, the pneumatic support rod 2 retracts and resets, ensuring sufficient stroke for the auxiliary support mechanism during use and effectively meeting on-site requirements.

[0055] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
