Description

Technical Field

[0001] This utility model relates to the field of parts processing fixtures, and in particular to a rotary clamping fixture for parts processing. Background Technology

[0002] In the machinery manufacturing industry, the precision machining of parts of various shapes and sizes is a common requirement. In order to ensure the stability of parts during machining, clamping fixtures are usually used to hold the parts, which makes it easier to fix the parts during machining and to adjust the angle and position, thereby improving the quality and flexibility of parts machining.

[0003] However, traditional clamping fixtures are usually simple in structure and are mostly fixed clamps that can only clamp parts from one direction. They cannot meet the processing needs of complex-shaped parts at different angles and can only clamp parts at a single height, making it difficult to guarantee different clamping requirements. When clamping parts with more complex shapes, the fixed-angle clamping structure is difficult to fit completely against the surface of the part, which can easily lead to insecure clamping or ineffective clamping.

[0004] Therefore, we provide a rotary clamping fixture for parts processing to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a rotary clamping fixture for parts processing, which aims to solve the aforementioned problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: it includes a support base, a rotating shaft seat is installed at the top of the support base, a clamping plate is installed at the top of the rotating shaft seat, a clamping assembly is provided on the upper side of the rotating shaft seat, the clamping assembly includes an installation groove formed on the surface of the clamping plate, a fixing plate is installed inside the installation groove, a connecting block is welded to the top of the fixing plate, a hydraulic clamping cylinder is installed at the top of the connecting block, and a clamping top plate is installed at the end of the hydraulic clamping cylinder.

[0007] Preferably, the clamping disc and the rotating shaft are welded together, the rotating shaft is driven by a motor inside the support base, and the clamping disc and the support base form a rotating structure through the rotating shaft.

[0008] Preferably, the mounting slots are provided in twelve sets, the fixing clamps are connected to the mounting slots by a slot connection, the mounting slots are provided with threaded grooves inside, and a locking bolt is installed on the top right side of the fixing clamps, the locking bolt passing through the fixing clamps and connecting to the clamping plate.

[0009] Preferably, the hydraulic clamping cylinder base is provided in three sets, which are evenly distributed at 120°. The clamping top plate forms a telescopic structure through the hydraulic clamping cylinder. An auxiliary support rod is welded to the bottom end of the clamping top plate, and the auxiliary support rod is slidably connected to the connecting block.

[0010] Preferably, a connecting slide is installed at the right end of the clamping top plate, a clamping plate is welded to the right end of the connecting slide, and pressure sensors are installed at the upper and lower ends of the connecting slide. The pressure sensors are electrically connected to the hydraulic clamping cylinder.

[0011] Preferably, the right end of the clamping top plate is connected to an adjusting top plate by a pin, and two sets of adjusting top plates are provided, with a protective pad adhered to the surface of the adjusting top plate.

[0012] Preferably, the clamping disc has an inner mounting groove at its center, a hydraulic adjusting column is installed inside the inner mounting groove, and a supporting top plate is welded to the top of the hydraulic adjusting column.

[0013] This utility model provides a rotary clamping fixture for machining parts. Compared with the prior art, it has the following advantages:

[0014] 1. This rotary clamping fixture for machining parts uses a motor to drive a rotating shaft seat, allowing the clamping plate to rotate flexibly. This facilitates machining operations on parts clamped on the clamping plate at different angles. When clamping parts, different numbers and positions of mounting slots can be flexibly selected according to the size and shape of the parts to install and fix the clamping plates. The fixing plates are then securely fixed to the clamping plate with locking bolts, making it easy to clamp parts from different angles. This improves the convenience and firmness of clamping irregular parts. At the same time, the height of the support top plate can be adjusted by a hydraulic adjusting column, which, together with the clamping top plate, facilitates clamping parts at different positions, increasing the flexibility of adjusting the clamping position and improving the firmness of the clamping.

[0015] 2. This rotary clamping fixture for machining parts uses a pressure sensor to detect the clamping force in real time during the clamping process and transmits the detected pressure data to the control system of the hydraulic clamping cylinder. When the clamping force reaches a preset value, the control system automatically stops the further movement of the hydraulic clamping cylinder to prevent damage to the parts due to excessive clamping force. This effectively ensures the integrity and quality of the parts during the machining process. During clamping, two sets of rotatable and adjustable top plates can better conform to the surface shape of the parts. Especially for some parts with irregular surfaces, the rotatable and adjustable feature allows the adjusting top plates to make closer contact with the parts, improving the stability of clamping. The protective pads can play a buffering and protective role, preventing the adjusting top plates from directly contacting the parts and preventing scratches on the surface of the parts.

[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 1-4 This utility model provides a technical solution: a rotary clamping fixture for parts processing, including a support base 1, a rotary bearing 2 installed at the top of the support base 1, a clamping plate 3 installed at the top of the rotary bearing 2, a clamping assembly 4 provided on the upper side of the rotary bearing 2, the clamping assembly 4 including an installation groove 401 formed on the surface of the clamping plate 3, a fixing plate 402 installed on the inner side of the installation groove 401, a connecting block 404 welded to the top of the fixing plate 402, a hydraulic clamping cylinder 405 installed at the top of the connecting block 404, and a clamping top plate 406 installed at the end of the hydraulic clamping cylinder 405.

[0023] The clamping disc 3 and the rotating shaft seat 2 are welded together. The rotating shaft seat 2 is driven by a motor inside the support base 1. The clamping disc 3 and the support base 1 form a rotating structure through the rotating shaft seat 2.

[0024] During use, the parts to be processed are placed on the clamping plate 3, and then the rotating shaft seat 2 is driven by the motor to rotate, so that the clamping plate 3 can rotate flexibly, which facilitates the processing of the parts clamped on the clamping plate 3 at different angles, greatly improving the processing flexibility and efficiency.

[0025] The hydraulic clamping cylinders 405 are basically set in three sets and are evenly distributed at 120°. The clamping top plate 406 forms a telescopic structure through the hydraulic clamping cylinders 405. An auxiliary support rod 412 is welded to the bottom end of the clamping top plate 406. The auxiliary support rod 412 and the connecting block 404 are slidably connected.

[0026] When clamping the parts, the hydraulic clamping cylinder 405 drives the three sets of clamping top plates 406 to retract inward, thereby clamping the parts. The auxiliary support rod 412 slides in the connecting block 404 to ensure the stability of the clamping top plate 406 during movement, avoids deviation or shaking, and ensures the accuracy of clamping.

[0027] The mounting slot 401 is provided with twelve sets. The fixing clamp 402 and the mounting slot 401 are connected by a slot. The mounting slot 401 has a threaded groove inside. A locking bolt 403 is installed on the top right side of the fixing clamp 402. The locking bolt 403 passes through the fixing clamp 402 and is connected to the clamping plate 3.

[0028] When clamping parts, different numbers and positions of mounting slots 401 can be flexibly selected according to the size and shape of the parts to install and fix the clamping plates 402. The clamping plates 402 are then firmly fixed to the clamping plate 3 by locking bolts 403, which facilitates clamping the parts from different angles and improves the convenience and firmness of clamping irregular parts.

[0029] A connecting slide 407 is installed on the right end of the clamping top plate 406. A clamping plate 408 is welded to the right end of the connecting slide 407. Pressure sensors 409 are installed at the upper and lower ends of the connecting slide 407. The pressure sensors 409 are connected to the hydraulic clamping cylinder 405.

[0030] During the clamping process, the pressure sensor 409 detects the clamping force in real time and transmits the detected pressure data to the control system of the hydraulic clamping cylinder 405. When the clamping force reaches the preset value, the control system will automatically stop the hydraulic clamping cylinder 405 from further action, preventing damage to the parts due to excessive clamping force, and effectively ensuring the integrity and quality of the parts during the processing.

[0031] The right end of the clamping top plate 406 is connected to an adjusting top plate 410 by a pin. There are two sets of adjusting top plates 410, and a protective pad 411 is adhered to the surface of the adjusting top plate 410.

[0032] During clamping, the two sets of rotatable and adjustable top plates 410 can better fit the surface shape of the parts. Especially for some parts with irregular surfaces, the rotatable and adjustable feature allows the top plates 410 to make closer contact with the parts, improving the stability of clamping. The protective pad 411 can play a buffering and protective role, preventing the top plates 410 from making direct hard contact with the parts and preventing scratches on the surface of the parts.

[0033] The clamping plate 3 has an inner mounting groove 413 in the center, and a hydraulic adjusting column 414 is installed inside the inner mounting groove 413. A supporting top plate 415 is welded to the top of the hydraulic adjusting column 414.

[0034] After placing the parts to be processed on the clamping plate 3, the height of the supporting top plate 415 is adjusted by the hydraulic adjusting column 414, so as to cooperate with the clamping top plate 406 to facilitate clamping the parts at different positions, increase the flexibility of adjusting the clamping position of the parts, and improve the clamping firmness.

[0035] Working principle: During use, the parts to be processed are placed on the clamping plate 3. Then, the height of the support plate 415 is adjusted by the hydraulic adjustment column 414 to change the height of the parts. Then, according to the size and shape of the parts, different numbers and positions of the mounting slots 401 are selected to install the fixing plates 402. The fixing plates 402 are then firmly fixed on the clamping plate 3 by the locking bolts 403.

[0036] Next, the hydraulic clamping cylinder 405 drives the clamping top plate 406 to retract inward, thereby clamping the parts. The auxiliary support rod 412 slides within the connecting block 404 to ensure the stability of the clamping top plate 406 during movement, preventing deviation or shaking. During the clamping process, the pressure sensor 409 detects the clamping force in real time and transmits the detected pressure data to the control system of the hydraulic clamping cylinder 405. When the clamping force reaches the preset value, the control system automatically stops the further movement of the hydraulic clamping cylinder 405.

[0037] Meanwhile, for some irregularly shaped parts, the rotatable adjustment feature allows the adjusting top plate 410 to make closer contact with the parts, improving clamping stability. The protective pad 411 acts as a buffer and protector, preventing the adjusting top plate 410 from directly contacting the parts and scratching their surfaces. Finally, during the part processing, the motor drives the rotating shaft seat 2 to rotate, thereby causing the clamping disc 3 to rotate the parts, allowing for processing operations at different angles.

[0038] 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.
