Description

Technical Field

[0001] This utility model relates to the field of broaching machine technology, and in particular to a broaching tool support platform for a broaching machine. Background Technology

[0002] A broaching machine is a machine tool that uses a broach as a cutting tool to machine through holes, planes, and shaped surfaces. Broaching can achieve high dimensional accuracy and low surface roughness, has high productivity, and is suitable for mass production. Most broaching machines only have the broach performing the main linear broaching motion, without a feed motion.

[0003] A horizontal broaching machine is a type of broaching machine used to machine holes or keyways. During machining, the workpiece generally remains stationary, while the broach performs linear cutting motion.

[0004] Broaching is a relatively precise method of hole machining. During machining, a large amount of metal slag remains on the broach and falls onto its platform. This necessitates cleaning the broach before each use. If slag remains, it can cause errors in machining the next workpiece, or even render the workpiece unusable. Therefore, the broach needs to be cleaned after each machining operation. Currently, this is done manually using an air gun to blow away the slag. This method is relatively simple, but broaches are long, reaching about 1.8 meters. When blowing air manually, a large amount of metal slag on the broach will fly everywhere, and there is a possibility that the flying slag will fall back onto the broach. This all requires manual cleaning. Moreover, when using a high-pressure air gun to blow away metal slag, it flies too high and is prone to bouncing, making it difficult to determine the landing point of the metal slag. As a result, it is necessary to repeatedly check whether there is any metal slag residue on the broach surface after each operation.

[0005] Based on this, the present invention designs a broach support platform for a broaching machine to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a broach support platform for a broaching machine. By adjusting the lifting rod, the height of the support can be adjusted, and the height of both ends of the support can be adjusted separately to adjust the lifting angle, thus stably mounting the broach on the base. The broach can also be adjusted to the same horizontal position as the workpiece on the broaching machine for easy cutting operations. A screen and a baffle plate are added, along with nozzles, to spray coolant onto the broach, effectively removing metal debris from its surface and reducing the likelihood of debris residue. This facilitates cleaning of the broach after each machining operation. A cooling pool and a mesh frame supply coolant to the nozzles, enabling the entire device to achieve coolant recycling. Furthermore, the cut metal debris can be collected centrally through the mesh frame for easy operation and convenient use.

[0018] The bottom of the cooling pool is also connected to a drain pipe, and each of the nozzles is connected to the drain pipe via a water pump.

[0019] Furthermore, a limiting rod is provided on both the front and rear sides of the left end edge of the base;

[0020] The limiting rod is vertically fixed to the top of the base;

[0021] An anti-detachment rod is also provided on the front and rear sides of the left end of the bracket. The anti-detachment rod extends horizontally on the front and rear sides of the bracket, and the two anti-detachment rods abut against the right ends of the limiting rod.

[0022] The left end of the bracket extends s into the cooling pool by a length s of 15cm;

[0028] Furthermore, the height of the baffle plate on the back of the base is between 70-90cm, and the height of the barrier net is 30cm;

[0029] The baffle plate is a closed stainless steel plate.

[0030] The barrier net is erected vertically above two anti-detachment poles on the left and right. There is a gap between the bottom of the barrier net and the bracket, with a gap interval of 10cm.

[0031] Furthermore, a filter screen is installed in the water inlet of the drain pipe;

[0032] A baffle plate is also provided on one side of the front of the base, and the height of the baffle plate on the front of the base does not exceed 20cm. All the nozzles are installed on the baffle plate on the front of the base.

[0033] The nozzle is located above the bracket, and the nozzle is a high-pressure nozzle. The nozzle sprays liquid in the direction directly towards the top of the bracket.

[0051] Please see Figures 1 to 6 As shown, this utility model provides a broach support platform for a broaching machine. To better understand the above technical solution, the following will describe the above technical solution in detail with reference to the accompanying drawings and specific embodiments.

[0052] In a specific embodiment of the technical solution of this utility model:

[0053] Includes base 1, bracket 2, cooling pool 3 and broaching bed 4;

[0054] The broaching machine 4 is set horizontally and is a horizontal broaching machine. A broach 41 is horizontally installed at the right end of the broaching machine 4.

[0055] The base 1, cooling pool 3 and broaching machine 4 are arranged from right to left. The joint between the base 1, cooling pool 3 and broaching machine 4 is sealed and connected as an integral structure, which can be fixed by welding.

[0056] Base 1 is a stable worktable with a lower left side and a higher right side.

[0057] Multiple nozzles 12 are also provided on the side of the base 1, and the water outlet of each nozzle 12 is directly facing the center of the base 1.

[0058] The side of the base 1 facing the cooling pool 3 is lower, facilitating the flow of coolant sprayed through the nozzle 12 into the cooling pool 3. A baffle 11 is vertically installed on the back of the base 1, completely covering the cooling pool 3 and the back of the base 1. The back is the side not operated by personnel, while the front is the side operated by personnel. Figure 1 The lower middle section is the front side, and the upper section is the back of the device.

[0059] The bracket 2 is a long strip support plate. Multiple lifting rods 22 are evenly installed on the front and rear sides of the bracket 2. The bracket 2 is placed on the base 1 by the multiple lifting rods 22. The support height of the bracket 2 on the base 1 is adjusted by the lifting rods 22. The left end of the bracket 2 extends directly above the cooling pool 3. The left end of the bracket 2 extends into the cooling pool 3 by a length s of 15cm.

[0060] The bottom of the lifting rod 22 is also provided with anti-slip texture, and the lifting rod 22 is a screw rod;

[0061] Multiple nuts are welded to the front and rear sides of the bracket 2, and the lifting rod 22 is vertically locked to the nuts of the bracket 2 by means of threads that can be raised and lowered.

[0062] The bracket 2 is erected above the base 1 without contact;

[0063] The bracket 2 is also equipped with a bubble level, which can be fixedly installed on the front side of the bracket 2 to make it easy for operators to check the level status of the bracket 2.

[0064] The bracket 2 is also equipped with multiple rollers 21. Each roller 21 is set parallel to each other at the same height. The rotation direction of each roller 21 is along the left and right direction. That is, the rotation direction of the roller 21 is the same as the travel direction of the cutter 41. The top arc surface of each roller 21 protrudes above the top surface of the bracket 2, and the protrusion height does not exceed 1cm.

[0065] A mesh 23 is also installed on the back of the bracket 2. The mesh 23 is a flat mesh plate.

[0066] The height of the liquid baffle 11 on the back of the base 1 is between 70-90cm, and the height of the net 23 is 30cm.

[0067] The liquid baffle 11 is a closed stainless steel plate;

[0068] The netting 23 is welded and fixed to the top of the back of the bracket 2, and the liquid baffle 11 is welded and fixed to the top of the back of the base.

[0069] The barrier net 23 is vertically erected above the two anti-detachment rods 24 on the left and right. There is a gap between the bottom of the barrier net 23 and the bracket 2, with a gap interval of 10cm. The function of this gap is to allow debris and coolant to flow onto the base 1, preventing metal debris from getting stuck on the bracket 2.

[0070] The broach 41 is mounted on top of the bracket 2 by multiple rollers 21 that roll in the left-right direction;

[0071] A limiting rod 13 is also provided on both the front and rear sides of the left edge of the base 1;

[0072] Limiting rod 13 is vertically fixed to the top of base 1;

[0073] An anti-slip bar 24 is also installed on the front and rear sides of the left end of the bracket 2. The anti-slip bar 24 extends horizontally on the front and rear sides of the bracket 2.

[0074] The two anti-detachment rods 24 abut against the right end of the limiting rod 13; two anti-detachment rods 24 are also set on the front and rear sides of the right end of the bracket 2. The four anti-detachment rods 24 and the bracket 2 form an H-shaped frame structure. The two anti-detachment rods 24 on the right end are only used as counterweights to ensure that the left and right ends of the bracket 2 are balanced and to prevent the right end of the bracket 2 from tilting up due to the left being heavier than the right.

[0075] The cooling pool 3 is a water tank with an opening at the top. A mesh frame 31 can be detachably installed at the opening at the top of the cooling pool 3. The mesh frame 31 covers the opening at the top of the cooling pool 3, and the top of the mesh frame 31 is lower than the height of the platform 1.

[0076] The bottom of the cooling pool 3 is also connected to a drain pipe 35, and each nozzle 12 is connected to the drain pipe 35 via a water pump. The inlet of the drain pipe 35 is equipped with a filter screen, which can be a fine high-density mesh to ensure that cutting debris cannot enter the water pump.

[0077] The frame 31 is a square frame with wire mesh panels on both the side walls and the bottom.

[0078] At least two annular handles 32 are provided on the bottom of the wire mesh frame 31 to facilitate personnel to lift the wire mesh frame 31 for dumping iron slag.

[0079] The inner sidewall of the cooling pool 3 has horizontally protruding baffle blocks 34 on both the left and right sides. The baffle blocks 34 are horizontally arranged flat plates.

[0080] Limiting blocks 33 are provided on the outer walls of both the left and right sides of the wire frame 31. The limiting blocks 33 are square blocks that extend outward.

[0081] The limiting frame 33 is stably mounted on the top of the support block 34, and the mesh frame 31 is placed in the inner cavity of the cooling pool 3 through the limiting frame 33 and the support block 34. The top of the mesh frame 31 is flush with the top of the cooling pool 3.

[0082] A baffle plate 11 is also provided on one side of the front of the base 1, and the height of the baffle plate 11 on the front of the base 1 does not exceed 20cm. The nozzles 12 are all installed on the baffle plate 11 on the front of the base 1. That is, the baffle plate 11 on the front of the base 1 is short, and the baffle plate 11 on the back is high, which makes it easier for the nozzles 12 to rinse the pull knife 41 and also prevents the debris from being sprayed out of the base 1 by the rinsing liquid.

[0083] The nozzle 12 is positioned above the bracket 2 to ensure that it can rinse the top of the cutter 41. The nozzle 12 is a high-pressure nozzle, and the spray direction of the nozzle 12 is directly facing the top of the bracket 2.

[0084] It should be noted that:

[0085] 1. The device is applicable to the horizontal broaching machine 4. The long rod on the left is a hydraulic tie rod, and the large square block in the middle is the fixture for fixing the workpiece. This fixture is also the existing structure of the broaching machine 4. The broach 41 is a long strip-shaped cutting tool. The broach 41 is dragged by the broaching machine 4 to pass through the workpiece and cut the workpiece into the set pattern.

[0086] 2. When the broach 41 processes the workpiece, the resulting metal slag is curved metal wire. Depending on the size of the workpiece, the length of the metal slag is generally less than 3cm and the diameter is small. The broach 41 will cut the workpiece into a lot of metal slag with different sized cutting edges. These metal slag are light in weight and are easily blown away by the air gun. They are not only scattered and difficult to collect, but will also fall on the surface of the broach 41 and affect the accuracy of the next processing.

[0087] After being washed and adhered to by the coolant, the metal fragments become heavier and fall off more easily. The fragments that fall to the top of the base 1 are no longer blown away by the large amount of coolant, but are instead washed into the mesh frame 31 by the water flow. The mesh 23 of this device can intercept the metal fragments and is mesh-like, allowing the coolant to pass through and carry more energy. The lighter metal fragments are cushioned by the mesh 23 after impact, making them less likely to splash. The heavier coolant, which carries more kinetic energy, is blocked by the baffle plate 11, so even if it splashes, it remains on the top of the base 1. The intercepted metal fragments and coolant will eventually fall onto the base 1, which is tilted towards the cooling pool 3. The coolant will push the lighter metal fragments into the mesh frame 31 for easy collection and processing.

[0088] 3. The lifting rod 22 of this device can be adjusted in height. Any lifting rod 22 can be adjusted individually to guide the tilt of the base 1 without affecting the level of the bracket 2. This makes the bracket 2 more level and supports the broach 41, making the broach 41 more smoothly pulled by the broaching machine 4.

[0089] When using this utility model, the workpiece is placed on the mounting frame at the far right end of the broaching machine 4, and then the broach 41 is pulled. After processing is completed, the broach 41 is pushed to the right again to disengage from the cutting position of the broaching machine 4.

[0090] At this time, a lot of debris is attached to the surface of the cutter 41. Personnel use an air gun to blow away the metal debris. At the same time, the nozzle 12 washes the cutter 41 on the top of the bracket 2. The metal debris is washed away from the cutter 41 by a large amount of coolant. Because the liquid washing not only has an impact force that can carry away the metal debris, but the coolant itself also has adhesive properties, which can carry the metal debris and achieve the purpose of collecting the metal debris.

[0091] Metal fragments are intercepted by the net 23 and fall onto the top of the base 1, while the coolant is intercepted by the net 23 and the baffle plate 11 and remains on the base 1. The net 23 can also buffer the impact force of the sprayed coolant. The coolant can carry the impact force through the net 23, while the metal fragments remain on the net 23. The metal fragments are light and have a small impact force, so the metal fragments can be effectively intercepted and fall onto the base 1. This device can be controlled by a PLC controller. As long as the pull knife 41 is pushed to the right, the nozzle 12 will be controlled to spray water, making the operation simpler and effectively reducing the chance of metal fragments splashing.
