Description

TECHNICAL FIELD

[0001] The utility model relates to sawtooth processing technical field especially relates to a sawtooth rake angle processing equipment. BACKGROUND

[0002] As an important cutting tool, the machining precision of the rake angle of the saw blade directly affects the cutting performance and service life. In the saw blade manufacturing process, the cutting head is usually driven to move along a specific trajectory by a cutting driving unit to achieve high-precision machining of the rake angle of the saw blade base. In the prior art, the cutting driving unit usually adopts an electric driving structure to control the movement position and angle parameter of the cutting head through a servo motor or a stepper motor. Under normal working conditions, the self-locking torque of the motor can maintain the position stability of the cutting head, thereby ensuring the consistency of the rake angle machining.

[0003] However, in actual production process, the equipment may be abnormally powered off due to power grid fluctuation, line fault and other reasons. At this time, the power supply of the electric driving system is interrupted, and the motor loses the supporting effect on the cutting head. Since the cutting head itself has a certain weight, and is usually in a cantilever state during machining, it is prone to fall or deviate under the action of gravity. This phenomenon can cause unexpected contact between the cutting head and the saw blade sawtooth, which may cause damage to the sawtooth edge, or even mechanical collision between the cutting head and the saw blade structure, resulting in sawtooth breakage or even equipment component damage. Such problems not only affect the machining quality, but also increase the downtime maintenance time and production cost.

[0004] Therefore, there is an urgent need for a solution that can quickly and reliably lock the position of the cutting head in the event of abnormal power failure, in order to improve the safety and stability of the saw blade rake angle machining equipment.

[0005] The above information disclosed in this background section is only included to enhance the understanding of the background of the present disclosure, and therefore can contain information that is not prior art known to those of ordinary skill in the art at the present time.

[0058] Referring to Figures 1-3 The present application provides a saw tooth rake angle processing equipment, comprising:

[0059] A fixed mounting plate 101 is provided.

[0060] A sliding mounting plate 102 is provided, which is connected to the fixed mounting plate 101 in an up-down sliding manner.

[0061] A saw blade fixing module 2 is provided, which comprises a saw blade fixing shaft 201 mounted on the fixed mounting plate 101 and used for inserting into a saw blade hole of a saw blade to be processed, and a saw blade clamping assembly 202 mounted on the fixed mounting plate 101 and used for clamping the saw blade to be processed.

[0062] A cutting module 3 is provided, which is mounted on the fixed mounting plate 101 and comprises a cutting head 301 used for cutting the rake angle of the saw blade to be processed, a horizontal direct drive mechanism 302 mounted on the sliding mounting plate 102, and a vertical direct drive mechanism 303 mounted on the fixed mounting plate 101. The driving end of the horizontal direct drive mechanism 302 is connected to the cutting head 301 to drive the cutting head 301 to move closer to or away from the saw blade to be processed in a horizontal direction. The driving end of the vertical direct drive mechanism 303 is connected to the sliding mounting plate 102 to drive the cutting head 301 to move closer to or away from the saw blade to be processed in a vertical direction.

[0063] A fall-preventing tension spring 103 is provided, which connects the fixed mounting plate 101 and the sliding mounting plate 102, and is used for limiting the sliding mounting plate 102 from sliding downward relative to the fixed mounting plate 101.

[0064] The saw tooth rake angle processing equipment provided in the embodiment has the following working process:

[0065] S10: Saw blade installation:

[0066] The center hole of the saw blade to be processed is sleeved on the saw blade fixing shaft 201, and the saw blade clamping assembly 202 is started to clamp the saw blade.

[0067] S20: rake angle cutting processing

[0068] The cutting head 301 rotates, and the horizontal direct drive mechanism 302 and the vertical direct drive mechanism 303 drive the cutting head 301 to cut into the saw tooth at a specific rake angle according to the programmed trajectory, and continuously feed to obtain the required rake angle.

[0069] In the above process:

[0070] When the power is cut off due to a fault anomaly, the vertical direct drive mechanism 303 loses the self-locking torque instantaneously, and the sliding mounting plate 102 and the cutting head 301 have a downward falling trend due to gravity;

[0071] At this time, the pre-designed anti-falling tension spring 103 immediately generates a reverse pulling force to offset the gravity torque, so that the sliding mounting plate 102 stops at the power-off instant position, and the cutting head 301 is prevented from falling downward and impacting the saw blade.

[0072] Therefore, the saw tooth rake angle processing equipment can effectively solve the problem that the cutting head 301 is easily damaged by falling in the existing processing equipment when the power is cut off abnormally.

[0073] In the embodiment, the saw tooth rake angle processing equipment further comprises a device cover 8. Figure 4 The device cover 8 is internally provided with a containing cavity, and the fixed mounting plate 101, the sliding mounting plate 102, the saw blade fixing module 2, the cutting module 3 and the anti-falling tension spring 103 are all located in the containing cavity.

[0074] Optionally, the bottom of the containing cavity is provided with a downward recessed drainage groove 801, the groove bottom of the drainage groove 801 is inclined downward from one end to the other end, and the lower end is provided with a drainage hole 802.

[0075] Further, the device cover 8 is provided with a trolley avoiding space 803 corresponding to the position of the drainage hole 802 for the storage trolley to enter and exit.

[0076] Optionally, the upper portion of the user storage trolley is further provided with a circulating pump 9 for pumping liquid from the storage trolley.

[0077] Generally, cutting processing needs to be continuously poured with cooling liquid. The downward recessed drainage groove 801 can recycle the cooling liquid and discharge it to the storage trolley through the drainage hole 802. After the storage trolley is full, the storage trolley can be pulled out, or the circulating pump 9 can be directly used to pump the cooling liquid in the storage trolley to the filtering device, and after filtering, the cooling liquid is poured onto the saw tooth again.

[0078] Optionally, the end face of the saw blade fixing shaft 201 is in a cylindrical structure or a sector structure.

[0079] In this embodiment, the saw blade fixing shaft 201 is installed on the hand screw rod distance adjusting assembly 203; the hand screw rod distance adjusting assembly 203 is used to adjust the initial horizontal distance size of the saw blade fixing shaft 201 to the cutting die set 3.

[0080] By manually fine-tuning the horizontal distance of the saw blade fixing shaft 201 and the cutting die set 3, the problem of high cost and complex maintenance of the traditional electronic distance adjusting system is solved. The operator does not need to rely on complex equipment to quickly adapt to saw blades of different diameters, especially suitable for small and medium-sized machining workshops or scenes where saw blade specifications are frequently changed.

[0081] In this embodiment, the saw blade clamping assembly 202 includes two clamping pads 2021 arranged on both sides of the saw blade to be machined, and a clamping direct drive mechanism 2022 connected to one of the clamping pads 2021 (the other clamping pad 2021 is fixedly arranged). When the clamping direct drive mechanism 2022 is extended, it can drive the two clamping pads 2021 to clamp the saw blade to be machined.

[0082] Further, by adjusting the extension stroke of the clamping direct drive mechanism 2022, the clamping force can be adjusted. Optionally, the clamping linear drive mechanism (such as a servo cylinder) supports 0.1mm level stroke control, which can adjust the clamping force in real time during the machining process, and meets the requirements of anti-looseness and anti-overpressure.

[0083] In this embodiment, the saw tooth rake angle machining device further comprises a tooth changing and pushing mechanism 4.

[0084] The tooth changing and pushing mechanism 4 is installed on the fixed mounting plate 101 and is used to push each saw tooth to realize the rotation and displacement of each saw tooth around the saw blade fixing shaft 201.

[0085] Specifically, the tooth changing and pushing mechanism 4 includes a transverse pushing needle 401 and a pushing needle XYZ three-direction direct drive module 402 for driving the transverse pushing needle 401 to perform translational motion.

[0086] The XYZ three-axis direct drive module drives the transverse pushing needle 401 to push the root of the saw tooth, so that the saw blade rotates around the saw blade fixing shaft 201, thereby realizing the displacement of the saw tooth, so as to machine the next saw tooth. It should be noted that when the saw tooth is displaced, the saw blade clamping assembly 202 needs to slightly loosen the saw blade to reduce the rotational resistance of the saw blade to be machined. However, it should not be completely loosened to avoid excessive rotation angle due to inertia when the saw tooth is pushed to change position.

[0087] Optionally, the saw tooth rake processing equipment further comprises a feeding rotary shaft 5 for storing unprocessed saw blades, a discharging rotary shaft 6 for storing processed saw blades, and a transfer manipulator 7 for transferring the saw blades. The feeding and discharging of the saw blades by the manipulator can improve the automation degree and further improve the production efficiency.

[0088] It should be noted that the direct drive mechanism mentioned in the present application can be a pneumatic cylinder, a hydraulic cylinder, an electric cylinder or a motor screw linear module, and the rotary drive mechanism mentioned can be a brush motor, a brushless motor or a rotary cylinder. The specific structure of the direct drive mechanism and the rotary drive mechanism is not limited.

[0089] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of the present application, it does not limit the patent protection scope of the present application. Any equivalent structure or equivalent process substitution or modification based on the essential concept of the present application, the content described in the specification and drawings, and the direct or indirect implementation of the technical solutions of the above embodiments in other related technical fields, are all included in the patent protection scope of the present application.
